How are exotic options classified and what makes them different from vanilla options?

Question

AcadiFi · Accepted Answer

Exotic options differ from vanilla European or American options because their payoff depends on more than just the terminal spot price. A useful classification groups them into four families: path-dependent options (Asian, lookback, barrier), correlation-based options (basket, rainbow, spread), time-dependent options (forward-start, cliquet, chooser), and payoff-modified options (binary, power, shout).

At Sequoia Derivatives Partners, analyst Priya Mahadevan teaches new associates to first ask: does the payoff care about the path of the underlying, or only its ending value? If only the ending value matters but the payoff function is unusual (digital, power), it is payoff-modified. If the path matters, it is path-dependent. If multiple assets are involved, it is correlation-based. If the strike or structure resets over time, it is time-dependent.

For the CFA, remember that exotics are typically priced using Monte Carlo simulation or trees rather than closed-form Black-Scholes, because path-dependence breaks the log-normal terminal distribution assumption.
