S&P 500 INDEX OPTIONS SETTLEMENT Are Standard & Poor’s 500 ($SPX) options settled American-style or European- style? Can they be assigned or exercised before expiration? S&P 500 options settle Europeanstyle, which means that they can only be exercised at expiration. In fact, most index options settle European-style. There are a few exceptions, however. For example, options on the S&P 100 ($OEX) settle American-style, and exercise or assignment can take place at any time prior to expiration. Exchange-traded funds (ETFs) also settle American-style, as do stock options, which can be exercised at any time before expiration. So traders who want to trade the S&P 500, but with options with American-style settlement, will trade options on the S&P 500 SPDRS (SPY) or “spiders,” because the SPY is an exchange-traded fund. However, to avoid the risk of early assignment with strategies like credit spreads, it’s sometimes better to use an index that settles European-style.
