Investopedia Says: Spiders are listed on the American Stock Exchange under the ticker symbol SPY. By trading like stocks, spiders have continuous liquidity, can be short sold, bought on margin, provide regular dividend payments and incur regular brokerage commissions when traded.
Spiders are used by large institutions and traders as bets on the overall direction of the market. They are also used by individual investors who believe in passive management (index investing).
