Leverage decay is real and it's brutal.

$CRWD up 13% over 5 days. You'd expect $CRWL (2x levered) to be up 26%. It's only up 22%. That's 4 points of slippage.

Flip side: $MRVL down 8.6%. $MVLL (2x levered) down 18.4%. That's actually tracking closer to 2x.

Why? Daily rebalancing + volatility drag. Levered ETFs reset exposure every day. If the underlying chops around, you bleed performance even if the net move looks clean. The path matters more than the destination.

Shorting levered ETFs exploits this structural decay. You're not just betting against the underlying—you're betting against the product itself. Over multi-day moves, especially volatile ones, the math works in your favor.

This is a trade, not a thesis. It's about execution and understanding the mechanics. If you're playing levered products long, you need to be right fast. If you're shorting them, time and volatility are on your side.
