The ProShares Short S&P 500 (SH) is an inverse exchange-traded fund designed to provide the opposite (-1x) of the daily performance of the S&P 500 Index. Launched in 2006, SH offers a straightforward way to hedge against market declines or express bearish views without short selling. Unlike leveraged inverse ETFs, SH aims for -100% daily return of the index, making it relatively less complex. However, due to daily rebalancing, long-term returns can still deviate from the exact inverse of the index. The fund is primarily used for short-term hedging and tactical trading strategies, though its single inverse exposure makes it more suitable for longer holding periods than leveraged products.
