The asymmetry trap everyone falls into: high-beta names that rip 2x the index on the way up but crater 3x on the way down. It's the cost of volatility—conviction gets expensive when momentum flips. If you're holding growth or spec plays, you're basically long gamma in bull runs and short it in corrections. Either size accordingly or accept you're trading emotional whiplash for upside. Most retail holds through both moves and ends up flat with max pain.
