SPY options on Reddit: what to know before you trade them

SPY options are the most traded options in the US, with expiries every weekday and tight spreads near the money. They settle in shares and can be assigned early, unlike SPX. Before a trade, check the implied move for your expiry and where the large gamma strikes sit, since they shape how SPY moves intraday.

SPY vs SPX

SPY is the ETF: options are American style, settle in shares, and can be assigned before expiry. SPX is the index: options are European style, settle in cash, and are ten times larger. SPX may also get different tax treatment in the US, so ask a tax professional.

Framing a trade

The implied move tells you what the market expects by expiry. A trade that needs more than that needs a reason. Gamma exposure shows where dealer hedging may slow or speed a move. Volume and open interest by strike show where the crowd is positioned.
