SPDR S&P 500 ETF
Selling a cash-secured put on SPDR S&P 500 ETF (SPY) means getting paid premium to set the price you'd buy the stock — while you wait. Set aside the strike × 100 per contract as collateral, and if SPY stays above your strike the put expires worthless and you keep the premium.
Implied volatility typically runs in the 12–22% range, so premiums are thinner than single names — but the liquidity and zero single-stock risk make it the default index-level covered call.
