+ETF Options
+Exchange-traded funds are vehicles that represent ownership in a fund or
+investment trust. This fund is made up of a basket of an underlying index’s
+securities—usually equities. The contract specifications of ETF options are
+similar to those of equity options. Let’s look at an example.
+One actively traded optionable ETF is the Standard & Poor’s Depositary
+Receipts (SPDRs or Spiders). Spider shares and options trade under the
+symbol SPY. Exercising one SPY call gives the exerciser a long position of
+100 shares of Spiders at the strike price of the option. Expiration for ETF
+options typically falls on the same day as for equity options—the Saturday
+following the third Friday of the month. The last trading day is the Friday
+before. ETF options are American exercise. Traders of ETFs should be
+aware of the relationship between the price of the ETF shares and the value
+of the underlying index. For example, the stated value of the Spiders is
+about one tenth the stated value of the S&P 500. The PowerShares QQQ
+ETF, representing the Nasdaq 100, is about one fortieth the stated value of
+the Nasdaq 100.
