SPXU — ProShares UltraPro Short S&P 500 -3x Inverse ETF
SPXU seeks -3x the daily return of the S&P 500, rising when markets fall and falling when markets rise. Like SQQQ, it is designed exclusively for short-term bearish trading. WARNING: Due to daily rebalancing and volatility decay, SPXU is not suitable for holding longer than a few days and will lose substantial value in any sustained equity bull market. In the long-run bull market trend of US equities, SPXU is a reliably wealth-destroying instrument for long-term holders.

Frequently Asked Questions
What is the difference between SPXU and SQQQ?
SPXU is -3x the S&P 500 (broad market); SQQQ is -3x the NASDAQ-100 (tech-heavy). SPXU is less volatile as the S&P 500 is more diversified. Both are inverse leveraged ETFs designed for short-term tactical bearish trading only. This is educational content, not financial advice.
Can SPXU protect my portfolio in a crash?
SPXU can provide short-term crash protection as a hedge, but it must be purchased before the crash and sold quickly during or after. If you hold SPXU through a recovery, the subsequent bull market will destroy SPXU's value rapidly. This is educational content, not financial advice.
What is -3x leverage?
For every 1% the S&P 500 moves in a day, SPXU moves approximately -3% in the opposite direction. A 5% S&P 500 decline in a day would cause approximately +15% in SPXU. A 5% S&P 500 gain in a day would cause approximately -15% in SPXU. This is educational content, not financial advice.
How quickly does SPXU decay?
In a low-volatility bull market, SPXU loses roughly 10–30% per month due to the combination of market gains and volatility decay. In high-volatility sideways markets, decay can be severe even without a clear directional move. This is educational content, not financial advice.
Is SDS a better alternative than SPXU?
SDS provides -2x (not -3x) S&P 500 exposure. It has less volatility decay than SPXU but still carries all the same fundamental problems with daily rebalancing for multi-day holders. Less leverage means smaller losses but also smaller gains during market declines. This is educational content, not financial advice.
