Our take

Structural notes on how this fund behaves. Read our guide on the 6 warning signs.

Inverse
Warning

Inverse ETF — daily tool only

Delivers the inverse of the benchmark's daily return. The compounding path makes multi-day holding unpredictable even when the benchmark's total move goes your way. Legitimate as a one-day hedge; dangerous as a view.
