How to profit from a stock decline?
Two of the most common ways to profit from a stock's decline without shorting are options and inverse ETFs.

Inverse ETFs contain swaps and contracts that effectively replicate a short position. For example, SQQQ is an inverse ETF that moves in the opposite direction of QQQ. If you believe the price of QQQ shares will go down, then shorting QQQ, buying a put option on QQQ, and buying shares in SQQQ will all allow you to profit from a move down.
