People always ask why I run $SPX over $SPY — here's the breakdown:

• Tax edge: 60/40 long-term treatment even on day trades. Real money saved if you're active.

• Overnight access: Trade after hours when news drops and cash is closed. That flexibility matters.

• Cash-settled: No assignment risk, no share delivery. Clean entries, clean exits.

Same underlying, tighter structure. If you're sizing up or trading frequently, $SPX is the move.

What's your setup — $SPX or $SPY?
