Correct, that’s typical circumstances for them. Those will only benefit when there are sharp sell-offs in the market. Other than that, they bleed/leak value until the next major sell-off.
When the next massive sell-off happens, they’ll come to life. But until then, they likely won’t.
I like UVXY better than the ones you mentioned. It doesn’t bleed quite as bad in the bad times for it (when markets are up, sideways or mildly down) but responds great in good times for it (when sell-offs are quick/large and volatility is higher).
