What Is SDOW? ProShares UltraPro Short Dow30
Short answer
SDOW is ProShares' -3x inverse leveraged ETF on the Dow Jones Industrial Average, designed to deliver three times the opposite of the Dow's daily return so it gains when the Dow drops. It is built only for single-day exposure: a daily reset and compounding cause returns over longer periods to diverge from -3x the index, and because U.S. markets tend to rise over time, holding SDOW for more than a few days typically bleeds value, often toward zero. It is a short-term trading and hedging instrument, not a long-term investment.
SDOW is issued by ProShares and tracks -3x daily Dow Jones Industrial Average. It charges a 0.95% expense ratio, holds approximately approximately $199 million in assets under management, yields about variable, recently around 5% (from interest on cash collateral, not a stable payout), and launched in February 9, 2010.

SDOW is issued by ProShares and tracks -3x daily Dow Jones Industrial Average, so a single ticker gives you the whole basket of underlying holdings weighted by the index's methodology rather than by any active stock-picking.
SDOW holdings: what's actually inside
SDOW does not hold a basket of individual stocks. It gets its exposure synthetically, through derivatives such as swaps and futures rather than by owning the underlying shares, so there is no conventional top-10 equity holdings list. See the description above for what SDOW actually tracks and how that exposure is built.
The bottom line on SDOW
SDOW is a specialized -3x inverse tool for traders who want to profit from or hedge against a short-term Dow decline. Its 0.95% expense ratio is high, and far more importantly, its daily reset, compounding, and volatility decay make it unsuitable for holding longer than a few days. Over weeks, months, or years it tends to erode toward zero because the stock market generally trends upward. Only experienced investors who actively monitor positions and fully understand inverse leveraged products should consider it, and even then only for short-term tactical use.

FAQ
What is SDOW?
+
SDOW is the ProShares UltraPro Short Dow30, a -3x inverse leveraged exchange-traded fund. It seeks daily results equal to three times the inverse of the Dow Jones Industrial Average's daily performance, meaning it is designed to rise about 3% when the Dow falls 1% on a given day and fall about 3% when the Dow rises 1%. It uses derivatives such as swaps and futures to achieve this and is intended for short-term trading, not long-term holding.
What is SDOW's expense ratio?
+
SDOW has an expense ratio of 0.95%, or about $9.50 per year on a $1,000 investment. That is high compared with plain index ETFs and reflects the cost of running a daily-reset, derivatives-based inverse leveraged strategy. ProShares has agreed to waive certain expenses to keep the ratio at this level through September 30, 2026.
What does SDOW track?
+
SDOW tracks the Dow Jones Industrial Average, a price-weighted index of 30 large U.S. companies, but on an inverse and leveraged basis. Its objective is -3x the index's daily return, so it is built to move in the opposite direction of the Dow and by roughly three times the magnitude on any single trading day. It does not hold the 30 Dow stocks; it uses derivatives to obtain the inverse exposure.
Should I hold SDOW long term?
+
No. SDOW is explicitly designed for single-day exposure and is not meant to be held long term. Its daily reset means returns compound day to day, so over weeks or months its performance can diverge sharply from -3x the Dow's cumulative move. Volatility decay erodes value in choppy markets even when the index ends flat, and because U.S. stocks tend to rise over time, a long-term SDOW position usually bleeds value and can drift toward zero. Treat it strictly as a short-term trade or hedge that you monitor actively.
How does a -3x inverse ETF work?
+
A -3x inverse ETF like SDOW uses derivatives such as index swaps and futures to deliver three times the opposite of its benchmark's daily return. If the Dow falls 1% in a day, SDOW aims to gain about 3%; if the Dow rises 1%, SDOW aims to lose about 3%. Crucially, the fund rebalances every day to reset that -3x exposure, so its returns compound over multiple days. This daily reset is why holding periods longer than one day produce results that differ, often substantially, from -3x the index's longer-term performance.
Is SDOW a good investment?
+
Walnut is informational, not investment advice. SDOW is not a traditional buy-and-hold investment; it is a tactical trading tool. It can be useful for experienced traders making a short-term bet that the Dow will fall or briefly hedging a portfolio, but its 0.95% expense ratio, daily reset, compounding effects, and volatility decay make it inappropriate for most investors and dangerous to hold over long periods, where it tends to lose value steadily. Anyone considering it should fully understand inverse leveraged products and monitor the position closely.
What is the difference between SDOW and UDOW?
+
SDOW and UDOW are sibling ProShares funds on the same index but in opposite directions. SDOW is the -3x inverse fund that aims to profit when the Dow falls, while UDOW (ProShares UltraPro Dow30) is the +3x bull fund that aims to profit when the Dow rises. Both reset daily and carry the same long-term holding risks from compounding and volatility decay, so each is intended for short-term trading rather than buy-and-hold investing.
Why does SDOW lose value when the Dow is flat over time?
+
Because SDOW resets its -3x exposure every day, its longer-term return depends on the path the Dow takes, not just the start and end levels. In a market that swings up and down but ends roughly flat, the daily compounding of leveraged inverse returns produces a net loss, a phenomenon called volatility decay. This is an inherent feature of daily-reset leveraged and inverse ETFs and is a key reason SDOW is meant for very short holding periods rather than extended ownership.
How do I compare SDOW to similar ETFs?
+
Put a few fields side by side: the expense ratio (fees compound over decades), the index or strategy it tracks, the top holdings and how much they overlap with what you already own, the dividend yield, and the AUM, liquidity, and bid-ask spread that affect trading costs. For index funds, tracking error (how closely it follows its index) and tax efficiency matter too. SDOW's figures are above; the full method is in Walnut's guide on how to compare ETFs.
