Key Takeaways
The ProShares Ultra Bitcoin ETF (NYSEARCA:BITU), a fund designed to deliver twice the daily return of Bitcoin, has declined 31% year-to-date, a stark contrast to the underlying asset's 10% drop in the same period. The significant underperformance highlights the inherent risks of volatility decay in daily leveraged financial products.
The fund’s structure, which resets its 2x leverage target daily, is the primary driver of this divergence. "Compounded across many days, results diverge from a static 2x of Bitcoin’s cumulative move, and the divergence almost always works against the holder when the path is choppy," the fund's prospectus outlines. This means that while BITU aims to double Bitcoin's performance on a given day, its long-term returns can and do decouple dramatically.
The numbers illustrate the powerful effect of this decay. While Bitcoin is down 10% year-to-date, a simple 2x leverage would imply a 20% loss for BITU; the actual loss is 31%. Over the past year, Bitcoin has fallen 17%, but BITU has plunged 53%. The mechanism is simple arithmetic: if Bitcoin falls 10% and then rises 10%, it is down 1% overall. A 2x fund like BITU would fall 20% and then rise 20%, leaving it with a larger 4% loss. However, in a steadily trending market, the fund can deliver its promised amplification. Bitcoin’s 16% gain in the past month resulted in a 30% return for BITU, close to a true 2x performance.
The risk for investors is treating a short-term trading instrument as a long-term investment. The fund's design means a sustained drawdown in the underlying asset is amplified; a 50% decline in Bitcoin could result in a near-total loss for BITU holders. The product is a wager that Bitcoin will trend strongly in one direction without the significant daily reversals that characterize its trading history. For anyone holding longer than a single session, the cost of the fund's structure is paid daily through the compounding effect of volatility.
