What's new

Everything within reach, from any page

• ImprovedThe header now sits in two rows: the tools you use most on top, and every destination below — all six atlases, Common Threads, the Quiet Room, the Big Data journey and Work with Phil. The lower row slides sideways instead of wrapping, so nothing gets squeezed on a laptop or a phone.
• AddedThe Quiet Room and the Big Data Decision Journey now appear on the home page alongside the atlases, and the Big Data journey has its own page at /bigdata explaining what it is before you start.
• ImprovedContact links across the site now use Dr Nguyen’s Western Sydney University address.

The angler, painted in ink

• ImprovedThe Angler scene is now an ink-wash painting: a rice-paper ground, a distant mountain wash, a lone boat and fisher in a few brush strokes, and a small red seal in the corner.

A faint word on the water

• AddedA single faint calligraphy word rests low on the still-water scenes — a quiet flourish, never in the way of the reading. And even more reflections now cycle through.

A patient angler, and more to read

• AddedA new Angler scene: a lone figure at a still golden-hour lake, rod out and float resting — the kind of quiet that asks you to sit and wait.
• ImprovedMany more reflections now cycle through, so the room stays fresh on repeat visits instead of showing the same few lines.

The Quiet Room, easier to read into

• AddedA new Meadow scene: a calm green field of gently swaying grass, for when you would rather rest your eyes on green than on water.
• ImprovedThe reflection now sits in a soft wash of light instead of a boxy panel, a short line under the title says what the room is for, the water invites a tap, and the scene drifts just enough to feel alive. The scene chips are clearer (Local time, Meadow, and the rest).

The Quiet Room grows a few gentle controls

• AddedThe Quiet Room now has things to do: choose the scene (dawn, day, dusk, night, or rain), turn on soft ambient sound (rain, a stream, waves, or a warm pad — all opt-in, with a volume you control), follow an optional breathing pacer, and stir the water with a tap. Everything still respects reduced-motion and stays silent until you press play.
• AddedA "Still water" state, for when even the controls feel like too much: they step back, the surface settles to a mirror, and you stay until you choose to leave — nothing counted, nothing to finish. The reflections now carry a few quieter, Daoist-tinged lines about water and enough, with the occasional empty turn.

The Quiet Room

• AddedA new page for a pause between study rounds: a quiet sky-and-water scene that follows your local time of day, one gentle line at a time, and an optional one-minute pause. Nothing here is marked, scored, or saved. Find it in the footer, or after you finish a Revise session.
• FixedRestored the site’s serif typography (Fraunces headings, Source Serif body) on recent Chrome versions, which had silently fallen back to a plain sans-serif.

The full teaching platform, on one profile

• AddedThe academic profile now lists all six interactive teaching atlases (derivatives, money and banking, financial modelling, investment management, security analysis and valuation, and financial risk management) alongside the new Decision Journey practice pilot.
• ImprovedThe downloadable CV (PDF and DOCX) now covers the Decision Journey practice platform.

Big Data Decision Journey — a practice pilot

• AddedThe homepage now links to the Big Data Decision Journey: a seven-mission game to practise evidence-led decisions for a Big Data in Finance course (125.788). It is an ungraded formative pilot, your progress is saved privately in your own browser, and it opens in a new tab.

New lesson: pricing an option with a binomial tree

• AddedA new 6-minute video lesson prices a call option by hand with one-step and two-step binomial trees, from the risk-neutral probability through to backward induction. It plays on the one-step and two-step binomial tree concept pages and in the Lessons library.

Back up and restore your study progress

Your study progress lives on your device — now you can export it to a file and restore it later, so clearing your browser or switching computers no longer loses your streak and reviews.

• AddedRevise now has "Export backup" and "Import" controls: save your reviews, streak, and progress to a small file, and restore them any time or on another device. No account needed.

Study-streak accuracy fix

• FixedThe study streak now handles a missed day correctly: one skipped day is forgiven, but it no longer lets an every-other-day pattern hold a streak indefinitely. The review-interval hints under each rating are also always in order now.

A study streak you can see, with a calendar

Revise now opens with a bold streak counter and a month calendar that marks the days you studied and circles today.

• AddedRevise now shows a prominent study-streak counter with a flame, plus a month calendar that fills in each day you review and highlights today — so you can see your rhythm at a glance.

Search-bar fix and smarter review order

• FixedOn the atlas pages, the search box no longer gets squeezed on mid-width laptop screens.
• ImprovedStudy mode now orders cards sensibly — the most overdue first, then new concepts from foundational to advanced, rather than in a fixed list order.

Spaced repetition comes to Revise

Revise now schedules concepts for you: review what is due, rate how well you recalled it, and build a daily streak. Everything stays on your device, no account needed.

• AddedA new Study mode in Revise uses spaced repetition (the FSRS algorithm): it shows the concepts due today, you rate how well you recalled each one, and it schedules the next review for you automatically.
• AddedA daily study streak and a "cards due today" count give you a reason to come back. Progress is saved on your device — no sign-in.
• AddedFinish a review session and you can download a shareable progress card.

Assign to Google Classroom, and recall-before-you-read prompts

Sharing a concept or tool with a class is now one click, and every concept invites you to recall the key idea before reading the details.

• AddedA "Share to Classroom" button on every concept page and on the Tools directory posts the page straight to Google Classroom — handy for assigning a tool to your students.
• AddedEach concept now shows a quick "recall" prompt right after the intuition: try to answer before revealing it, which helps the idea stick.
• ImprovedEmbedded tools now always carry a clear link back to the full concept, so every embed credits the source.

Free interactive tools, now embeddable

Every interactive tool now has a home in one directory, and you can drop any of them into your own site, blog, or LMS with a single snippet.

• AddedA new Tools directory gathers all 61 interactive finance calculators and explorers in one place, grouped by course.
• AddedEvery tool has an "Embed this tool" button that copies a ready-made snippet, so you can place the live, interactive tool on your own website or learning platform. It resizes itself to fit.
• AddedA new "For instructors" page explains how to link, embed, cite, and reuse the atlas in your teaching (free, non-commercial, with attribution).

Every concept links to more of its neighbours

Concept pages now surface more of the surrounding topic map, so it is easier to keep exploring without going back to the atlas.

• ImprovedEach concept page now suggests more connected concepts: related links count both directions, and a new "More in this theme" row points to other concepts in the same cluster to explore next.

Put-Call Parity, now narrated

The Put-Call Parity lesson now plays a fuller, narrated walkthrough of the no-arbitrage link between every call and put.

• ImprovedThe Put-Call Parity lesson video is now a narrated walkthrough, on both the lesson page and the Atlas concept page.

Watch on YouTube and subscribe, right from each lesson

Every lesson video keeps playing seamlessly on the site, and now also offers a one-click way to open the full player on YouTube or subscribe to the channel. Both open in a new tab, so your place on the site is never lost.

• AddedEach lesson video now shows a "Watch on YouTube" and a "Subscribe" button, and the Lessons page has a Subscribe card at the end. All open in a new tab, so you can keep studying on the site while supporting the channel.

Tidier footer on phones

A small pass after walking the site: the footer navigation now wraps to fit phone screens instead of overflowing, and the concept total on the engagement page is computed from the live atlases so it stays accurate.

• FixedOn phones, the footer navigation links now wrap to fit the screen instead of running off the right edge.

The atlas filter button stays fully on screen

On the main atlas, the filter toggle in the top bar could be clipped at the right edge on some laptop widths. It now stays fully visible, and the course switcher quietly takes the squeeze instead.

• FixedThe filter toggle in the atlas top bar is no longer cut off at the right edge on laptop-width screens.

Cleaner spacing and a tidier header on laptops

Concept pages now use their full intended spacing between sections, headings, and cards, and the top navigation no longer crowds or clips on laptop-width screens.

• ImprovedConcept pages and panels now show their intended spacing between sections, headings, and cards, so they read more comfortably.
• FixedThe top navigation no longer overflows on laptop-width screens. The course switcher uses compact course names (hover for the full name) and stays tidy as the window narrows.

Concept pages now sit centred on wide screens

On large monitors the concept reading column was hugging the left edge with a lot of empty space on the right. It now sits centred, with comfortable padding on both sides.

• FixedConcept pages now centre on the screen instead of pinning to the left on wide monitors, so the notes, video, and quiz read more comfortably. Thank you again to the student who flagged it.

Open any concept full-screen from the atlas

Clicking a concept in the atlas opens a side panel with its notes, video, and quiz. You can now open that same concept as a full page in one click, from a new expand button at the top of the panel.

• ImprovedA new expand button sits at the top of the concept side panel (next to the close button). One click opens the full concept page, so you can read the notes, watch the video, and take the quiz with the whole screen. Suggested by a Western Sydney University student.

Common Threads, redrawn to read at a glance

The cross-course map is redrawn to read at a glance. The lines linking each shared concept to the courses that teach it are now visible at rest and coloured by course, a plain-language reading key sits above the map, and hovering any course shows exactly which concepts it shares.

• ImprovedThe Common Threads map now shows its connections at rest: the line from each shared concept to every course that teaches it is visible and coloured by that course, so you can read the whole structure without hovering.
• AddedHovering any course now shows a tooltip with its full name and the exact concepts it shares with the other courses. Hovering a concept still shows its rationale and a link into each course that teaches it.
• ImprovedA plain-language reading key now sits above the map, and each concept carries small course-coloured dots showing how many courses share it.

Four Money & Banking videos, plus an English-first homepage

Four animated lessons land on the Money & Banking atlas and play right on their concept pages: the efficient markets hypothesis, rational expectations, the three theories of the yield curve, and how prices reveal information. The site now opens in English by default, with a one-tap switch to Vietnamese, and the Money & Banking map sits centred in the view.

• AddedFour animated video lessons on the Money & Banking atlas, embedded on their concept pages and listed under Lessons: the efficient markets hypothesis, rational expectations, the three theories of the yield curve (expectations, segmented markets, and the liquidity premium), and how prices reveal information (with the line between research and insider trading). Each is worked from Mishkin.
• ImprovedThe site now opens in English by default, with a one-tap switch to Vietnamese that is remembered for your next visit.
• FixedThe Money & Banking concept map now sits centred in the view. It previously drifted toward the bottom of the screen.

Two new Money & Banking concepts: term-structure theories and price discovery

The Money & Banking atlas gains two concepts. "Theories of the Term Structure" walks through the expectations, segmented-markets, and liquidity-premium theories of the yield curve, with the worked indifference number. "How Prices Reveal Information" explains why a price reflects the best-informed trader rather than the average opinion, and where the line falls between an edge you earn and insider trading.

• AddedA new Money & Banking concept, "Theories of the Term Structure", sitting beside the yield-curve page: the expectations theory (long rate as the average of expected future short rates), segmented markets, and the liquidity-premium synthesis with its term premium, plus the worked example (6% + 8%) / 2 = 7%. Concept page has formulas, an example, misconceptions, a quiz, and a Mishkin citation.
• AddedA new Money & Banking concept, "How Prices Reveal Information": why a market price reflects the best-informed traders at the margin rather than an average of opinions, how informed trading impounds information into prices, and the line between an edge you earn from public research and illegal trading on material non-public information.

Three videos bring the Panel Data cluster to life

The new Panel Data cluster on the Economic & Financial Modelling atlas gets its videos. Animated lessons now play on three concept pages: getting your data ready before any regression runs, the structure of panel data, and fixed effects, each worked in Stata.

• AddedThree animated video lessons on the Economic & Financial Modelling atlas, embedded on the Panel Data concept pages: data handling (merging and reshaping into a panel), panel data structure (cross-section meets time series), and fixed effects (the within estimator), each worked in Stata and listed under Lessons.

A Panel Data cluster joins the Economic & Financial Modelling atlas

The Economic & Financial Modelling atlas gains a seventh theme, Panel Data, the workhorse of applied project econometrics. Six new concepts walk from preparing and reshaping data, through panel structure and the naive pooled regression, to fixed effects, random effects with the Hausman test, and clustered standard errors. All Wooldridge-based and worked in Stata.

• AddedA new "Panel Data" cluster on the Economic & Financial Modelling atlas with six concepts: data handling (merging and reshaping into a panel), panel data structure (within vs between variation), pooled OLS, fixed effects (the within estimator), random effects and the Hausman test, and clustered standard errors. Each has intuition, formulas, worked Stata examples, a quiz, and Wooldridge citations.
• ImprovedThe Economic & Financial Modelling atlas now spans OLS, cross-section, time series, and panel data.

Two new videos: option combinations and why we take logs

Two more animated lessons land. On the Derivatives atlas, a new "Option Combinations and Spreads" concept (with a video) explains why a straddle is not just any two options, and how legs stack into strangles and spreads. On the Economic & Financial Modelling atlas, a video on functional form shows why regressions take logs and how to read a coefficient as an elasticity.

• AddedA new Derivatives concept, "Option Combinations and Spreads", with an animated video: how a straddle (call plus put, same strike) differs from a strangle (different strikes) and from a spread (same option type), and why the payoff of any position is the sum of its legs. Concept page has formulas, worked examples, a quiz, and citations.
• AddedA new animated video on the Economic & Financial Modelling atlas, "Functional Form: why we take logs", embedded on the Logs and Elasticities concept page: log-log slopes as elasticities, log-level slopes as semi-elasticities, and why skewed positive variables fit better in logs.

A new video on straddles, long and short

A new animated lesson on the straddle joins the Derivatives atlas. In four minutes it builds the long straddle, a bet that the market makes a big move in either direction, then flips it across the axis into the short straddle, a bet that the market stays still. It plays on both the Long Straddle and Short Straddle concept pages.

• AddedA new animated video lesson, "Straddles, long and short", on the Derivatives atlas: the long straddle (buy a call and a put to profit from a big move either way) and the short straddle (sell both to collect the premium if the market stays still), with payoffs and break-evens. Embedded on both the Long Straddle and Short Straddle concept pages and listed under Lessons.

Editorial roles on the homepage

The homepage profile now shows the journals Dr. Nguyen helps edit, alongside the journals he publishes in: Academic Editor at PLOS ONE, a Q1 multidisciplinary journal, and Editorial Review Board at the International Journal of Educational Management (Emerald, ABDC B, Scimago Q1 in education). Each links to the journal.

• ImprovedAdded an "Editorial roles" line to the homepage profile: Academic Editor at PLOS ONE (a Q1 multidisciplinary journal) and Editorial Review Board at the International Journal of Educational Management (Emerald, ABDC B, Scimago Q1 in education), each linking to the journal.

A new video on the yield curve, in the Money & Banking atlas

A new animated lesson on the term structure of interest rates joins the Money & Banking atlas. In under four minutes it builds the yield curve, explains its usual upward slope with the expectations theory and the liquidity premium, and shows why an inverted curve has so often warned of a coming recession. It plays right on the Term Structure and the Yield Curve concept page.

• AddedA new animated video lesson, "The Term Structure of Interest Rates", on the Money & Banking atlas: the yield curve, the expectations theory and liquidity premium that shape it, and why an inverted curve signals expected rate cuts and a possible recession. Embedded on the Term Structure and the Yield Curve concept page and listed under Lessons.

Richer search-engine and AI-answer structured data

Behind the scenes, every concept page now carries cleaner structured data so search engines and AI answer engines understand it better: each page describes itself as a learning resource, lists its questions and answers, and links to the course it belongs to. The six atlases now also describe themselves as courses, and the homepage lists them as a course catalogue. Page descriptions are cleaner and, for the most-searched concepts, hand-written.

• ImprovedEvery concept page now publishes structured data describing it as a learning resource, with its quiz rendered as a question-and-answer block and a link to its parent course, so search engines and AI answer engines can read and cite it more reliably.
• ImprovedEach of the six atlases now describes itself as an online course, and the homepage lists all six as a course catalogue.
• ImprovedPage descriptions are cleaner (cut at whole words, never mid-word), and the most-searched concepts (CAPM, the efficient frontier, market efficiency, WACC, enterprise DCF, Value at Risk) now carry hand-written descriptions tuned to how students search for them.

The first Investment Management video: arbitrage and liquidity

The Investment Management atlas gets its first animated lesson. A five and a half minute video on arbitrage and liquidity walks through classic, triangular, and latency arbitrage, and shows why every one of these riskless trades lives or dies on speed and the liquidity that someone has to provide. It plays right on the Market Structure and Trading concept page, next to the intuition, examples, and a quiz.

• AddedA new animated video lesson, "Arbitrage and Liquidity", on the Investment Management atlas: classic, triangular, and latency arbitrage, and how each depends on speed and on the liquidity providers earn a maker rebate for supplying. Embedded on the Market Structure and Trading concept page and listed under Lessons.

A clearer way in, a faster site, and a way to work together

This release makes the site easier to arrive at and easier to continue through. The homepage now greets Vietnamese visitors in Vietnamese and points everyone to a clear starting place. Every concept page ends with a suggested next concept and one-click sharing. A new Work with Phil page describes training, advisory, and speaking engagements. Under the hood, the five newer atlases load noticeably less code.

• AddedA "Work with Phil" page at /services describing corporate training and executive workshops, advisory and consulting, and speaking and guest lectures, with direct contact links. Linked from the header, the footer, and the profile page.
• AddedEvery concept page now closes with a "Next concept" suggestion, share buttons (copy link, Facebook, LinkedIn), and a quick way to follow or get in touch.
• AddedEach atlas page now carries a "Browse all concepts" index beneath the network, listing every concept by theme as plain links, for quick navigation without the graph.
• ImprovedThe homepage opens in Vietnamese for first-time visitors whose browser prefers Vietnamese, adds a clear "Explore the atlases" button, and offers a one-tap language switch right in the hero.
• ImprovedThe five newer atlases no longer download the derivatives course data they never use, and pages without mathematics no longer load the math renderer styles. Both changes make first loads lighter.
• FixedSwitching between atlases with theme filters active no longer risks an empty network view.
• FixedThe feedback page now opens your email client directly instead of pointing to a survey that was never linked.

Four ASX case studies join the valuation atlas

The Applied Cases on the Security Analysis and Business Valuation atlas now pair the five Vietnamese companies with four Australian ones, each chosen to teach a method the others do not. Commonwealth Bank shows why a bank is valued on the equity side rather than with an enterprise cash-flow model, CSL shows the real options hidden in a research pipeline, Transurban shows a finite-life toll-road concession with no perpetuity, and the Newmont acquisition of Newcrest shows precedent transactions and the control premium.

• AddedFour ASX-listed case studies on the Security Analysis and Business Valuation atlas: Commonwealth Bank (valuing a bank on the equity side with a dividend-discount and residual-income model and a price-to-book against return-on-equity check), CSL (real options in a drug pipeline, the right to expand, abandon or delay), Transurban (a finite-life toll-road concession valued with no Gordon perpetuity), and the 2023 Newmont acquisition of Newcrest (precedent-transaction multiples and the control premium). Each anchors to a verified reported figure and keeps the rest of the worked numbers illustrative.
• ImprovedThe Applied Cases now span nine companies across two markets, the Ho Chi Minh exchange and the ASX, so students see the same valuation toolkit applied to a wider range of businesses.

Two more risk tools, and a clearer Common Threads map

The Financial Risk Management atlas gains two interactive tools — a CoVaR explorer that shows how one bank in distress moves the whole system, and a bank stress-test simulator that walks capital from a starting ratio down through a severe scenario to a pass-or-fail call. The Common Threads map also gets a tidy-up so every course label reads clearly.

• AddedA CoVaR and Delta-CoVaR explorer on the Financial Risk Management atlas: drag the linkage, the institution size, and the confidence level to see how one bank moving from its median state into distress shifts the value-at-risk of the whole financial system.
• AddedA bank stress-test simulator on the Financial Risk Management atlas: set a starting CET1 ratio and a severe macro scenario (an equity shock, a property-price fall, and a rise in unemployment) and watch capital deplete step by step to a post-stress ratio with a pass-or-fail verdict, in the spirit of the CCAR and EU-wide exercises.
• FixedTidied the Common Threads map so every course atlas label reads clearly, with no overlap between the shared-concept chips and the course discs.

Four animated lessons join the Economic & Financial Modelling atlas

The first video lessons land on the Economic & Financial Modelling atlas: a four-part animated mini-series on time series — the nature of time-series data, the six regression assumptions, autocorrelation in the errors, and stationarity and unit roots. Each plays right on its concept page, next to the intuition, formulas, a worked Stata example, and a quiz.

• AddedFour animated video lessons on the Economic & Financial Modelling atlas, a time-series mini-series: the nature of time-series data, the six time-series regression assumptions (TS.1 to TS.6), autocorrelation in the regression errors, and stationarity and unit roots. Each lesson is embedded on its concept page next to the intuition, formulas, a worked Stata example, and a quiz.

The Financial Risk Management atlas turns interactive

Six new interactive tools land on the Financial Risk Management atlas: a Value-at-Risk calculator (parametric, historical, and Monte-Carlo side by side), a VaR backtester with the Basel traffic light, a liquidity-measures calculator, a sovereign-risk gauge, a stock-return-volatility explorer, and a systemic-risk SRISK calculator. Each updates live as you drag the sliders.

• AddedSix interactive widgets on the Financial Risk Management atlas — a Value-at-Risk calculator (parametric vs historical vs Monte-Carlo on the return distribution), a VaR backtester (exceptions, the Kupiec test, and the Basel traffic light), a liquidity-measures calculator (spreads, turnover, Amihud), a sovereign-risk gauge (debt-to-GDP, fiscal and external balances), a stock-return-volatility explorer (volatility vs beta), and a systemic-risk SRISK calculator — each recomputing live as you drag the sliders.

A sixth atlas: Financial Risk Management

A new Financial Risk Management atlas joins the family — 76 connected concepts across Value at Risk, financial-report quality, liquidity and stock-return volatility, sovereign risk, and systemic risk. Built on Jorion, Roncalli, and the GARP curriculum, and woven with real cases from LTCM and the 2008 crisis to Wirecard, the 2022 Sri Lanka default, and the 2023 banking turmoil.

• AddedA Financial Risk Management atlas at /frm_atlas: 76 concepts in eight themes — Value at Risk (parametric, historical, and Monte Carlo, with backtesting and Expected Shortfall), financial-report quality and earnings manipulation, liquidity and stock-return volatility, sovereign risk, and systemic risk (CoVaR, SRISK, contagion) — each with intuition, formulas, worked examples, real-world cases, a quiz, and academic citations.
• ImprovedThe homepage now showcases all six course atlases, 423 connected concepts in total.

The econometrics atlas is now Economic & Financial Modelling

The applied-econometrics atlas has been renamed to Economic & Financial Modelling, to match the course it supports and to state its scope up front: cross-section and time series, Wooldridge-based and taught in Stata, rather than panel or causal-inference methods. Existing links keep working — the address is unchanged.

• ImprovedRenamed the Econometrics atlas to Economic & Financial Modelling across the site (page titles, social cards, the Common Threads map, and the homepage), with its scope stated up front: applied econometrics in cross-section and time series. The web address is unchanged, so existing links and bookmarks still work.

A readability and keyboard-access polish

A focused accessibility pass across the home, atlas, revision, and profile pages. Link, brand, and label colours now meet contrast standards, the active navigation tab and filter controls read more clearly, and the key-formula box on each revision card can be scrolled with the keyboard.

• ImprovedHigher colour contrast on links, the active navigation tab, section labels, and filter controls across the home, atlas, revision, and profile pages, so text is easier to read (WCAG AA).
• ImprovedThe key-formula box on each revision card is now reachable and scrollable with the keyboard.
• FixedThe atlas filter button now announces a clear name to screen readers.

A video lesson on option profit diagrams

The Common Payoff Shapes concept now opens with a short animated lesson on the profit-and-loss diagrams that options produce at expiry: long and short calls and puts, the kink at the strike, and the breakeven.

• AddedA short animated video lesson on option profit diagrams at expiry (calls, puts, and the breakeven) on the Common Payoff Shapes concept and the Lessons page.

A plain-language glossary and an accessibility pass

A new Glossary collects the jargon that runs through all five atlases into one place, with short plain-language definitions. Alongside it, an accessibility pass lifts the concept drawer and the interactive controls to clearer, higher-contrast colours, and pages now load their animation code on demand.

• AddedA Glossary at /glossary: plain-language definitions of 40+ finance and econometrics terms — moneyness, the Greeks, WACC, beta, heteroskedasticity, and more — grouped by subject, with each term linking straight to its concept in the atlas where it has one.
• ImprovedAccessibility: cluster-coloured text in the concept drawer now meets WCAG AA contrast, the interactive sliders use the cobalt accent, and the welcome dialog keeps keyboard focus inside it.
• ImprovedFaster first loads: animation code is now loaded on demand, trimming the initial download on the atlas and concept pages.

Sharper sharing, lessons everywhere, and an accessibility pass

Every concept on all five atlases now generates its own social preview card, so sharing a link shows the concept title and its theme colour instead of a generic image. The Lessons library is reachable from every atlas, not just Derivatives. And a site-wide accessibility pass raised text and control contrast to WCAG AA and added keyboard focus handling to the welcome dialog.

• AddedPer-concept social preview images across all five atlases, so sharing any concept link shows a card with its title and theme colour.
• ImprovedThe Lessons library is now reachable from the navigation on every atlas, not only Derivatives.
• ImprovedA site-wide accessibility pass: higher text and control contrast (WCAG AA), clearer lesson and difficulty labels, and keyboard focus handling in the welcome dialog.

Valuation tools, real-company cases, and a fifth thread

The Security Analysis & Business Valuation atlas gains seven interactive tools, an enterprise DCF, a WACC builder, beta unlevering, a sensitivity tornado, relative-valuation multiples, adjusted present value, and a value-driver model, plus five worked real-company cases drawn from listed Vietnamese firms. It also joins Common Threads as the fifth course, connected by a new cost-of-capital thread.

• AddedSeven interactive valuation tools on the Security Analysis & Business Valuation atlas: enterprise DCF, WACC builder, beta unlevering, sensitivity tornado, relative multiples, adjusted present value, and value drivers.
• AddedFive worked real-company valuation cases anchored to listed Vietnamese firms: Vinamilk, Hoa Phat, FPT, Masan, and Mobile World.
• AddedThe valuation atlas now appears on the Common Threads map as the fifth course, linked through a new cost-of-capital thread.

A video lesson on what an option is

The Options Basics concept in the Derivatives atlas now opens with a short animated video lesson on what an option is, covering calls, puts, the premium, and why the buyer loss is capped.

• AddedA short animated video lesson introducing options (calls, puts, and the premium) on the Derivatives Options Basics concept and the Lessons page.

A fifth atlas: Security Analysis & Business Valuation

A new interactive concept atlas joins the platform, covering security analysis and business valuation: forecasting and valuing cash flows, project risk, the cost of capital, required returns, financial-statement forecasting, value creation, relative valuation, enterprise DCF, private equity and real options. Seventy-six connected concepts across ten clusters, anchored on Titman and Martin, with worked examples, quizzes and citations on every concept.

• AddedA new Security Analysis & Business Valuation atlas: 76 concepts across 10 clusters, from discounted cash flow and the cost of capital to relative valuation, enterprise DCF, private equity and real options. Anchored on Titman and Martin.

A video lesson on deflation and Japan’s lost decades

The deflation concept in the Money and Banking atlas now opens with a short animated video lesson that walks through the deflationary spiral, debt-deflation, the zero-lower-bound trap, and Japan as the real-world case.

• AddedA short animated video lesson on deflation, embedded on the Money and Banking concept page and listed on the Lessons page.

A new concept on deflation and Japan’s lost decades

The Money and Banking atlas gains a concept on deflation and persistently low inflation, anchored to Japan’s experience since the late 1990s. It explains the deflationary spiral, Irving Fisher’s debt-deflation, and why a falling price level is so dangerous once interest rates are near zero, which is why central banks aim for a small positive inflation rate rather than zero.

• AddedA Money and Banking concept on deflation, debt-deflation, and the zero lower bound, with Japan’s lost decades as the real-world case.

Accessibility, mobile, and search polish

A polish pass across the four atlases. Labels that read gold on a white card now use a darker, easier-to-read gold that meets accessibility contrast. The concept map and the widgets sit better on phones and tablets, with larger tap targets and a graph that no longer hides under the mobile browser bar. Search now tells you when nothing matches, and all four course atlases are searchable, not just Derivatives.

• ImprovedGold labels on white now meet WCAG AA contrast, tap targets are larger, and the concept map and widgets fit phones and tablets better.
• ImprovedSearch shows a clear no-results message and is now available on all four course atlases, not only Derivatives.

A model-specification sandbox, swap comparative advantage, and three more real cases

Econometrics gains a specification sandbox that shows, on one scatter, how functional form (logs and elasticities), a squared term, and dummy variables each change what a coefficient means. Derivatives gains a comparative-advantage swap allocator that splits the quality-spread differential between two firms and a dealer. Money and Banking links its open-market-operations page to the reserves-market tool. Three more concepts are anchored to verified events: the Terra and Luna stablecoin collapse of 2022, the Asian financial crisis of 1997, and the GameStop short squeeze of 2021.

• AddedAn Econometrics specification sandbox (functional form, polynomials and interactions, dummy variables) and a Derivatives comparative-advantage swap allocator.
• AddedVerified real-world cases woven into Money and Banking: Terra and Luna 2022, the Asian financial crisis 1997, and the GameStop short squeeze 2021.
• ImprovedThe open-market-operations page now opens the interactive reserves-market tool.

Seven new interactive tools, and real cases, across all four courses

Every course gains hands-on widgets. Econometrics gets a Monte-Carlo sampling-distribution simulator and a t-test and confidence-interval explorer. Money and Banking gets a bank-run and deposit-insurance simulator. Derivatives gets counterparty exposure, futures-to-spot convergence, and a rate-futures profit-and-loss explorer. Investment Management gets a Sharpe, Treynor and Jensen performance dashboard. Several concepts are now anchored to verified real events: Silicon Valley Bank in 2023, the State Bank of Vietnam managed float, Lehman Brothers in 2008, the Volcker disinflation, and the Granger and Newbold spurious-regression study.

• AddedSeven new interactive widgets across Econometrics, Money and Banking, Derivatives, and Investment Management, from a sampling-distribution simulator to a bank-run model and a fund performance dashboard.
• AddedReal-world case studies woven into the concepts with verified figures: Silicon Valley Bank 2023, the State Bank of Vietnam central-rate regime, Lehman Brothers 2008, the Volcker disinflation, and Granger and Newbold (1974).
• ImprovedMore concepts across the four atlases now open an interactive tool.

New interactive tools and a smoother atlas

Three new interactive widgets join the Derivatives atlas: an American early-exercise tree that shows when exercising early beats holding, a daily mark-to-market ledger that fires margin calls along a price path, and a Greeks dashboard for all five sensitivities. The atlas itself is friendlier too — a first-visit guide, a visible "explored" progress counter, and a direct link from every video lesson into the matching concept.

• AddedThree new interactive Derivatives widgets: American early-exercise, a daily mark-to-market ledger with margin calls, and a Black-Scholes Greeks dashboard.
• AddedA first-visit guide to the concept map, a visible progress counter for concepts you have explored, and a link from each video lesson straight to its concept in the atlas.
• ImprovedThe atlas concept map is now fully keyboard-navigable and respects the system reduce-motion setting, and pages load lighter across the site.

Common Threads: how the courses connect

A new page draws the four course atlases as one picture and shows the concepts they share. Present value, bond pricing, duration, risk and return, market efficiency, stock valuation, behavioural finance, and regression all recur across courses, and Common Threads lets you hover any one to see where it appears and follow it into each atlas. It is the connective tissue between Derivatives, Money & Banking, Econometrics, and Investment Management.

• AddedA new "Common Threads" page that maps the four course atlases and the shared concepts that connect them, with a link from each concept into every course that teaches it.

More hands-on Money & Banking tools

Four more interactive tools join the Money & Banking atlas. You can run the quantity theory of money and watch inflation track money growth net of real output, work the Fisher equation to see how an inflation surprise erodes the real return on a nominal loan, explore the market for reserves to see how a central bank’s floor system pins the policy rate, and test purchasing power parity to read the exchange rate implied by two price levels and spot an over or under-valued currency.

• AddedFour interactive tools on the Money & Banking atlas: a quantity-theory-of-money explorer, a Fisher-equation tool separating expected from realized inflation, a market-for-reserves diagram showing how the policy rate is set, and a purchasing-power-parity exchange-rate tool.

The Investment Management Atlas becomes hands-on

Interactive tools now sit on the Investment Management atlas. You can drag the two-asset efficient frontier and watch a lower correlation bow it toward the axis, switch it to show the capital allocation line and the Sharpe-maximising tangency portfolio, slide a beta along the Security Market Line to read the CAPM-required return and spot under or over-valued stocks, value a share with the Gordon growth model and watch the price explode as growth approaches the required return, and model how a startup founder is diluted across funding rounds. The bond price-and-yield and duration-and-convexity tools carry over to the fixed-income concepts too.

• AddedInteractive tools on twelve Investment Management concepts: an efficient-frontier and capital-allocation-line explorer, a CAPM and Security Market Line tool, a Gordon-growth dividend-discount valuer, a startup pre-money, post-money and dilution model, and the bond price-yield and duration-convexity tools reused on the fixed-income concepts.

A fourth atlas: Investment Management

The site now hosts a fourth interactive atlas, for Investment Management, anchored on Brailsford, Heaney and Bilson. It opens with 57 concepts across eight themes: the investment environment, fixed income, market efficiency, fundamental analysis, technical and quantitative analysis, portfolio optimization and asset pricing, startup fundraising, and ethics. It follows the working analyst from sizing up a market and an asset class, through valuing a company and building an optimized portfolio, to raising capital for a venture and the ethics that bind the profession.

• AddedAn Investment Management Atlas of 57 connected concepts across eight themes, from the CAPM, the efficient frontier, and fundamental valuation to bond duration, behavioural finance, venture-capital fundraising, and the CFA Institute Standards, each with the intuition, key formulas, a worked example, common misconceptions, a quiz, and academic citations.
• AddedThe course switcher now spans four atlases, Derivatives, Money & Banking, Econometrics, and Investment Management, all featured on the home page.

The Econometrics Atlas becomes hands-on

Five interactive tools now sit on the Econometrics Atlas, one on each core idea. You can drag a regression line and watch the sum of squared residuals refuse to beat the least-squares fit, dial up omitted-variable bias and see the short regression drift away from the truth, compare classical and heteroskedasticity-robust standard errors on the same estimate, slide an AR(1) coefficient from mean reversion through a random walk to an explosive path, and turn up the correlation between two regressors to watch the variance inflation factor blow up. Each tool lives on its concept page and in the atlas detail panel.

• AddedInteractive tools on nine econometrics concepts: an OLS line-and-residuals explorer (with the R² decomposition), an omitted-variable-bias simulator, a classical-versus-robust standard-error comparison, a random-walk versus AR(1) unit-root explorer, and a multicollinearity and variance-inflation-factor tool.

A third atlas: Econometrics

The site now hosts a third interactive atlas, for Economic and Financial Modelling, anchored on Wooldridge. It opens with 49 concepts across six themes: foundations and data, simple regression, multiple regression and inference, specification and data problems, heteroskedasticity, and time series. Each concept carries the intuition, the key formulas, a worked example in Stata, the common misconceptions, a quick quiz, and academic citations, and the spine of the atlas follows the working econometrician from assumption to violation to test to remedy.

• AddedAn Econometrics Atlas of 49 connected concepts across six themes, from the Gauss-Markov assumptions and omitted-variable bias to heteroskedasticity-robust inference, unit roots, and cointegration, each with the intuition, key formulas, a worked Stata example, common misconceptions, a quiz, and academic citations.
• AddedThe course switcher now spans three atlases, Derivatives, Money & Banking, and Econometrics, all featured on the home page.
• ImprovedSharper, more legible colours for section headings, formula labels, and topic links on every concept page in light mode.

Real-world case studies

The Money & Banking atlas now carries eight integrative case studies that tie the concepts together around real events: the 2008 Global Financial Crisis, the Volcker disinflation, the Great Inflation of the 1970s, the 1997 Asian financial crisis, the GameStop short squeeze, the Terra-Luna stablecoin collapse, the March 2020 dash for cash, and how Vietnam navigates the exchange-rate trilemma. Each case links the concept nodes it draws on, so you can watch the theory play out in history.

• AddedEight case-study nodes in the Money & Banking atlas, each synthesising several concepts around one real event, from the 2008 crisis and the Volcker disinflation to the GameStop squeeze, the Terra-Luna collapse, and Vietnam and the trilemma.

A second atlas: Money & Banking

The site now hosts a second interactive atlas, for Money, Banking and Financial Markets, anchored on Mishkin. It opened with 31 concepts and has grown to 53 across six themes: interest rates and the term structure, central banking and monetary policy, the stock market and efficiency, money, crypto and CBDCs, banking and financial regulation, and international finance. Hands-on tools sit on the core concepts, and a switcher in the header moves between the two atlases.

• AddedA Money & Banking Atlas of 53 connected concepts across six themes, each with the intuition, key formulas, a worked example, common misconceptions, a quiz, and academic citations.
• AddedInteractive tools on its core concepts: the money multiplier, the Taylor rule, Gordon-growth stock valuation, the bond market, the exchange-rate trilemma, interest parity, bank capital and leverage, and a stablecoin run.
• AddedA course switcher in the header to move between the Derivatives and Money & Banking atlases, both featured on the home page.

The Atlas becomes hands-on

Interactive tools grew from a single calculator to tools on 65 derivatives concepts. You can shape an option’s Greeks, draw a payoff at expiry, price an option with Black-Scholes or a binomial tree, build the fair futures price from the cost of carry, size a hedge, value an interest-rate swap, read a forward rate off the yield curve, and watch a bond’s price move with its yield through duration and convexity. Each tool lives on its concept page and in the Atlas detail panel, and follows you onto related concepts.

• AddedInteractive tools on 65 concepts: margin calls, an option-strategy builder, a Black-Scholes pricer, a binomial tree, cost-of-carry futures, bond price-and-yield, option Greeks, payoff diagrams, hedge sizing, swap valuation, forward rates, and duration and convexity.
• AddedTwo new concepts, Duration and Convexity, each with its own bond-risk tool that shows the convexity correction to the straight-line duration estimate.
• ImprovedThe pricing tools follow you onto related concepts, so the right one tends to be waiting wherever you land.

The site goes bilingual

The home page and the full academic profile gained an English and Vietnamese toggle, remembered between visits. The Vietnamese version is a natural rewrite for Vietnamese students and visitors, not a machine translation, while course names, journals, and the atlases themselves stay in English. Vietnamese accents render as clean single glyphs everywhere, and every font now loads from the site itself for a faster first paint.

• AddedAn English and Vietnamese toggle on the home page and the academic profile, with the choice remembered on your next visit.
• ImprovedCrisp Vietnamese diacritics across the site, with the page fonts self-hosted for faster loading and no third-party request.

Animated video lessons

A new Lessons gallery brings hand-coded animated lectures, each drawn frame by frame in Python with no generative AI in the visuals. The first set covers the derivatives core, from put-call parity, the call option, and futures payoff to risk-neutral probability, interest-rate swaps, Black-Scholes-Merton, and how futures margin accounts and contracts work. Concepts that carry a video are marked on the Atlas, and each lesson embeds on its concept page.

• AddedA Lessons gallery of animated finance lectures grouped by topic, each hand-coded in Python, with its own page and an inline embed on the matching Atlas concept.
• AddedThe Atlas marks concepts that have a video with a gold ring and a play badge, with a video-only filter and a Watch-the-lesson link in each detail panel.

The personal-brand layer

The landing and profile grew into a proper academic home. A magazine-cover hero from Western Sydney University’s Meet Our Lecturers series, a downloadable CV, a Press and Media section with a featured video and Vietnamese press coverage, a What-I-offer services menu, live Google Scholar metrics, and faculty cards carrying school logos and ranking medals.

• AddedA downloadable academic CV (PDF and DOCX), a Press and Media section with Vietnamese press features and a featured video, and a What-I-offer services menu.
• AddedLive Google Scholar metrics on the profile, a Western Sydney University cover image, and faculty cards with school logos and verified ranking medals.

Editorial refresh and a more readable Atlas

A visual maturation of the whole site. The default theme moved to a soft blue-tinted editorial light mode with a two-colour system, gold for the brand and cobalt for interaction, with a warm-charcoal dark mode a click away. Atlas labels stay legible at every zoom, light mode gained real contrast, emoji gave way to clean line icons, search shows tappable results, and the graph reads well on phones.

• AddedA two-colour accent system, gold for the brand and cobalt for interaction, over a soft blue-tinted editorial light theme with a warm-charcoal dark mode.
• AddedTappable search results, a photo gallery, a live screenshot of the Atlas, and a richer landing with a stats bar and recent papers.
• ImprovedReadable Atlas labels at every zoom, real light-mode contrast, line icons in place of emoji, and a mobile-friendly graph with a collapsible legend.
