Our take

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

Inverse
Warning

You can be right and still lose

This fund returns the opposite of its benchmark's daily move, then resets. Hold it longer and the daily compounding takes over: the market can move your way over a week and you still finish down. It works as a one-day hedge and nothing beyond that.
