Call Options, the right to buy and how leverage cuts both ways

A call is the right, not the obligation, to buy at the strike. Payoff, profit, breakeven, and why leverage cuts both ways, with a worked CBA example.

InteractiveExplore Call Option in the Atlas

A 2 minute animated lesson on the call option, the right but not the obligation to buy a stock at a fixed strike price. Built for FIN301 students at Western Sydney University and anyone meeting options for the first time.

The video draws the payoff max(S_T - K, 0), shifts it down by the premium to get profit, and marks the breakeven at strike plus premium. A worked CBA example with a A$50 strike and a A$3 premium shows the two faces of leverage. At A$58 the trade returns about 167% on the premium. At A$48 the call lapses and the whole premium is lost.

The lesson closes on what students most often get wrong. A call is a right, not a duty, you exercise only when the stock is above the strike, and a profit needs the stock above strike plus premium, not just above the strike. Pair the video with the Atlas concept page for formulas, a quiz, and citations to Hull (2022) and Merton (1973).
