The Direxion Daily S&P 500 Bear 3x Shares ETF (NYSEARCA:SPXS) is one of the most popular instruments to short the broad market for trading or hedging purposes. However, its daily -3X leverage factor is a source of drift. It must be closely monitored to detect changes in the drift regime. This article explains what "drift" means, quantifies it in more than 20 leveraged ETFs, shows historical data, and finally concludes about the current market conditions. The analysis is also valid for the ProShares UltraPro Short S&P 500 ETF (SPXU), which tracks the same index with the same factor and has an almost identical behavior.
Why do leveraged ETFs drift?
Leveraged ETFs often underperform their underlying index leveraged by the same factor. The decay has essentially four reasons: beta-slippage, roll yield, tracking errors, management costs. Beta-slippage is the main reason in equity leveraged ETFs. However, when an asset is in a steady trend, leveraged ETFs can bring an excess return instead of a decay.

Monthly and yearly drift watchlist
There is no standard or universal definition of leveraged ETF drift. Mine is simple and based on the difference between the leveraged ETF performance and Ñ times the performance of the underlying index on a given time interval, if Ñ is the leveraging factor. Most of the time, this factor defines a daily objective relative to an underlying index. However, some dividend-oriented leveraged products have been defined with a monthly objective (mostly defunct ETNs sponsored by Credit Suisse and UBS: CEFL, BDCL, SDYL, MLPQ, MORL…).
First, let’s start by defining “Return”: it is the return of a leveraged ETF in a given time interval, including dividends. “IndexReturn” is the return of a non-leveraged ETF on the same underlying asset in the same time interval, including dividends. “Abs” is the absolute value operator. My “Drift” is the drift of a leveraged ETF normalized to the underlying index exposure in a time interval. It is calculated as follows:
Drift = (Return - (IndexReturn x Ñ))/ Abs(Ñ)
“Decay” means negative drift. “Month” stands for 21 trading days, “year” for 252 trading days.

The best and worst drifts
- The inverse leveraged biotechnology ETF (LABD) has the largest monthly decay of this list with a drift of -2.96%.
- The same fund also has the worst 1-year decay: -20.53%. The only other product listed here with a 2-digit annual decay is the inverse leveraged silver ETF (ZSL) at -12.38%
- The inverse leveraged real estate ETF (DRV) has the highest, though moderate monthly positive drift (+0.60%).
- DRV also shows the largest annual positive drift (+20.47%), followed by the inverse leveraged semiconductors ETF (SOXS, +20.14%), both in large losses.
Positive drift follows a steady trend in the underlying asset, whatever the trend direction and the ETF direction. It means positive drift may come with a gain or a loss for the ETF. For example, you can see in the table above that all leveraged ETFs in large-cap US stock indexes and REITs have positive drifts on a trailing year (both long and inverse ones). Negative drift comes when daily returns skip between positive and negative values (“whipsaw”). You can also see that leveraged ETFs in gold, silver and biotechnology have negative drifts on the long and the short sides.
SPXS drift history
Since inception in November 2008, SPXS has lost 99.98% of its value, going through a number of reverse splits. However, hedging with SPXS has worked quite well in many cases in the last 12 years. For example, in the first week of the 2020 market meltdown (2/21 to 2/28/2020), it has gained about 40%, significantly more than SPY's return (-11%) multiplied by the leveraging ratio (-3). Then, I have issued a warning on 3/10/2020 against leveraged equity ETFs. A few weeks later, SPY had lost 17.5% and SPXS gained about 16% in the same time: less than shorting SPY without leverage. Then, the monthly drift has oscillated between positive and negative values, and the 12-month drift was negative until February 2021. It jumped back in positive territory and spiked in April. The next chart plots the 12-month drift since January 2000, using real prices from November 2008, and synthetic prices based on the underlying index before that. The historical average is negative: -3.03%.

SPXS is an efficient hedging instrument against sharp corrections in a bull market. Moreover, the cost of hedging is quite cheap compared with other derivatives. However, it suffers a large decay when the S&P 500 has alternatively positive and negative days. The VIX index (implied volatility) may be a warning, but it is not mathematically related to decay. On top of that, keep in mind that shorting an asset or buying an inverse ETF implies an additional decay due to inflation and magnified by the leveraging factor.
In conclusion, leveraged ETFs are only for seasoned traders with a good understanding of their behavior behind the advertised leveraging factor. For other investors, it is preferable to never touch them.
