Inverse ETFs: How They Work and Key Risks
Inverse ETFs go up when stocks go down. Sounds useful — but the math makes them a guaranteed losing bet over time.
Don't have time? Here's what you need to know:
- 1Inverse ETFs lose money long-term because the stock market trends upward over time
- 2SQQQ has lost 95%+ over any 5-year period — a reliable wealth destroyer
- 3Even during crashes, inverse ETFs require perfect timing to produce positive returns
- 4Better alternatives: bonds (BND), cash reserves, patience, and continuing to invest through downturns
Inverse ETFs: Betting Against the Market
An inverse ETF delivers the opposite of its index's daily return. SH (ProShares Short S&P 500) aims to return -1x the S&P 500 daily. If the S&P rises 1%, SH falls 1%. If the S&P falls 1%, SH rises 1%. The idea is portfolio protection during downturns — profit when stocks crash. The reality: since stocks go up about 7 out of every 10 years, inverse ETFs lose money the vast majority of the time.
Leveraged inverse ETFs (SQQQ, SPXU) deliver -2x or -3x the daily return. They suffer from both the upward drift of markets AND volatility decay. SQQQ has lost 95%+ of its value over any 5-year period. These are the most reliably money-losing investments available.
Why Inverse ETFs Are Guaranteed Long-Term Losers
The stock market has returned roughly 10% per year for a century. An inverse ETF loses roughly 10% per year from that upward drift alone — before volatility decay and fees. Adding 0.90% in annual expenses makes it worse. The daily reset adds more drag.
Even during a crash, inverse ETFs may not save you. The 2020 crash lasted 33 days. If you bought SH at the start and held for 2 months, you would have earned about 20% — only to lose it all within weeks as the market recovered 50%+ by summer. Timing the entry and exit perfectly is nearly impossible.
Better Ways to Protect Your Portfolio
Instead of inverse ETFs: (1) Hold bonds (BND, BSV) — they often rise when stocks fall and do not decay over time. (2) Keep cash reserves for buying opportunities during crashes. (3) Use options (put contracts) if you need specific downside protection — they have defined costs and expirations. (4) Simply accept that market drops happen and keep investing through them.
The cheapest downside protection is patience. Every stock market decline has been followed by a recovery. The investors who buy more during crashes do far better than those who try to profit from the crash itself.
Important: Holding an inverse ETF for any period longer than one day is almost certainly losing you money. SQQQ has lost 99%+ from its initial value. These products exist for professional day traders, not for portfolio protection.

Frequently Asked Questions
Can inverse ETFs protect my portfolio during a crash?
In theory, yes — for exactly one day at a time. In practice, crashes are impossible to time. If you buy SH and the market rises for 3 weeks before crashing, you lose money on SH during those 3 weeks. The protection only works if you time both the entry and exit perfectly.
Why do inverse ETFs exist if they always lose money?
Day traders use them for single-day bets against the market. Market makers use them for hedging. Some institutional strategies require short exposure for a few hours. The intended holding period is one trading session — not days, weeks, or months.
Is there any safe way to bet against the market?
Not cheaply or simply. Put options provide defined-cost protection with an expiration date. But they are complex instruments that most beginners should avoid. For most investors, the best 'protection' is a well-diversified portfolio with bonds and cash for rebalancing.
