InteractiveExplore How Prices Reveal Information in the Atlas

A 2 minute 51 second animated lesson on price discovery, how a market price comes to reflect what informed people know. Built for students of money, banking and financial markets, and for anyone curious how trading turns scattered information into a single price.

It opens with one stock and two investors who disagree, and asks whose valuation sets the price. The answer is neither the average. Whoever has done the work and is willing to trade keeps pushing the price until the easy profit is gone, so the price ends up reflecting the best informed view rather than the crowd. A stock at one hundred that informed analysts value at one hundred and ten gets bought up toward that value.

It closes on the line the law draws. Trading on your own analysis of public information is legal and is exactly how prices stay informative. Trading on material non public information obtained through a position of trust is insider trading, an edge stolen rather than earned.
