"Exotic" Options With Standard Exercise Styles
These options can be exercised either European style or American style; they differ from the plain vanilla option only in the calculation of their payoff value:
- A cross option (or composite option) is an option on some underlying asset in one currency with a strike denominated in another currency. For example a standard call option on IBM, which is denominated in dollars pays $MAX(S−K,0) (where S is the stock price at maturity and K is the strike). A composite stock option might pay JPYMAX(S/Q−K,0), where Q is the prevailing FX rate. The pricing of such options naturally needs to take into account FX volatility and the correlation between the exchange rate of the two currencies involved and the underlying stock price.
- A quanto option is a cross option in which the exchange rate is fixed at the outset of the trade, typically at 1. The payoff of an IBM quanto call option would then be JPYmax(S−K,0).
- An exchange option is the right to exchange one asset for another (such as a sugar future for a corporate bond).
- A basket option is an option on the weighted average of several underlyings
- A rainbow option is a basket option where the weightings depend on the final performances of the components. A common special case is an option on the worst-performing of several stocks.
- A Low Exercise Price Option (LEPO) is a European style call option with a low exercise price of $0.01.
- A Boston Option is an American option but with premium deferred until the option expiration date.

Famous quotes containing the words exotic, standard, exercise and/or styles:
“Anthropology has always struggled with an intense, fascinated repulsion towards its subject.... [The anthropologist] submits himself to the exotic to confirm his own inner alienation as an urban intellectual.”
—Susan Sontag (b. 1933)
“If the Revolution has the right to destroy bridges and art monuments whenever necessary, it will stop still less from laying its hand on any tendency in art which, no matter how great its achievement in form, threatens to disintegrate the revolutionary environment or to arouse the internal forces of the Revolution, that is, the proletariat, the peasantry and the intelligentsia, to a hostile opposition to one another. Our standard is, clearly, political, imperative and intolerant.”
—Leon Trotsky (1879–1940)
“I would not that death should take me asleep. I would not have him meerly seise me, and onely declare me to be dead, but win me, and overcome me. When I must shipwrack, I would do it in a sea, where mine impotencie might have some excuse; not in a sullen weedy lake, where I could not have so much as exercise for my swimming.”
—John Donne (c. 1572–1631)
“The gothic is singular in this; one seems easily at home in the renaissance; one is not too strange in the Byzantine; as for the Roman, it is ourselves; and we could walk blindfolded through every chink and cranny of the Greek mind; all these styles seem modern when we come close to them; but the gothic gets away.”
—Henry Brooks Adams (1838–1918)
