| 释义 |
In finance, an exotic option is an option which has features making it more complex than commonly traded vanilla options. Like the more general exotic derivatives they may have several triggers relating to determination of payoff. An exotic option may also include non-standard underlying instrument, developed for a particular client or for a particular market. Exotic options are more complex than options that trade on an exchange, and are generally traded over the counter (OTC). EtymologyThe term "exotic option" was popularized by Mark Rubinstein's 1990 working paper (published 1992, with Eric Reiner) "Exotic Options", with the term based either on exotic wagers in horse racing, or due to the use of international terms such as "Asian option", suggesting the "exotic Orient".[1][1] Journalist Brian Palmer used the "successful $1 bet on the superfecta" in the 2010 Kentucky Derby that "paid a whopping $101,284.60" as an example of the controversial high-risk, high-payout exotic bets that were observed by track-watchers since the 1970s in his article about why we use the term exotic for certain types of financial instrument. Palmer compared these horse racing bets to the controversial emerging exotic financial instruments that concerned then-chairman of the Federal Reserve Paul Volcker in 1980. He argued that just as the exotic wagers survived the media controversy so will the exotic options.[2] In 1987, Bankers Trust Mark Standish and David Spaughton, were in Tokyo on business when "they developed the first commercially used pricing formula for options linked to the average price of crude oil." They called this exotic option, the Asian option, because they were in Asia.[3] DevelopmentExotic options are often created by financial engineers and rely on complex models to price them. FeaturesA straight call or put option, either American or European, would be considered non-exotic or vanilla option. An exotic option could have one or more of the following features:
Even products traded actively in the market can have the characteristics of exotic options, such as convertible bonds, whose valuation can depend on the price and volatility of the underlying equity, the credit rating, the level and volatility of interest rates, and the correlations between these factors. BarriersBarriers in exotic option are determined by the underlying price and ability of the stock to be active or inactive during the trade period, for instance up-and –out option has a high chance of being inactive should the underlying price go beyond the marked barrier. Down-and-in-option is very likely to be active should the underlying prices of the stock go below the marked barrier. Up-and-in option is very likely to be active should the underlying price go beyond the marked barrier.[4]One-touch double barrier binary options are path-dependent options in which the existence and payment of the options depend on the movement of the underlying price through their option life.
