SRTY is issued by ProShares and tracks -3x daily Russell 2000, 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.
SRTY holdings: what's actually inside
SRTY 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 SRTY actually tracks and how that exposure is built.
The bottom line on SRTY
SRTY is a specialized, high-risk -3x inverse tool for traders who want to profit from or hedge against short-term declines in U.S. small-cap stocks. The daily reset and -3x leverage create real compounding decay, and holding it for weeks or months can lose money even if the Russell 2000 falls, because the path of returns matters more than the destination. Combined with a high 0.95% expense ratio, it is built for short holding periods with active monitoring, not for long-term investing. Walnut is informational, not investment advice.

FAQ
What is SRTY?
+
SRTY is the ProShares UltraPro Short Russell2000, a -3x inverse leveraged exchange-traded fund. It seeks to deliver three times the opposite of the daily return of the Russell 2000 small-cap index, so it is designed to rise when small-cap stocks fall on a given day. It is a short-term trading and hedging tool, not a long-term holding.
What is SRTY's expense ratio?
+
SRTY has an expense ratio of about 0.95% per year. That is high compared with plain index ETFs and reflects the cost of running a leveraged, derivatives-based strategy. This ongoing fee adds to the decay you face from daily resetting, which is one reason SRTY is intended for short holding periods rather than long-term ownership.
What does SRTY track?
+
SRTY tracks negative three times the daily performance of the Russell 2000 Index, a benchmark of roughly 2,000 U.S. small-cap companies. It does not hold those stocks directly; instead it uses swaps and other derivatives to create -3x inverse exposure. The -3x objective applies to a single trading day, and longer-term results can differ substantially from -3x the index move.
Should I hold SRTY long term?
+
No. SRTY is built for short-term trading, not long-term holding. Because it resets its -3x target every day, returns compound over time in a path-dependent way, and in volatile or sideways markets this typically causes meaningful decay. You can lose money even if the Russell 2000 falls over the period you hold it. Combined with the roughly 0.95% expense ratio, the value tends to bleed lower the longer you hold, which is why these funds are meant for days, not months or years.
How does a -3x inverse ETF work?
+
A -3x inverse ETF aims to deliver three times the opposite of its index's return for one trading day. If the Russell 2000 falls 1% in a day, SRTY targets roughly a 3% gain that day, before fees; if the index rises 1%, SRTY targets about a 3% loss. Each day it resets to that -3x goal, so over multiple days returns compound off a new base. This daily reset means longer-term results depend on the path the index takes, and volatility can produce decay that drags the fund below a simple -3x of the index's overall move.
Is SRTY a good investment?
+
SRTY is not a traditional investment; it is a tactical trading instrument for sophisticated, active traders who want short-term downside exposure to small caps or a brief hedge. Its -3x leverage, daily reset decay, and roughly 0.95% expense ratio make it high risk and generally unsuitable for buy-and-hold investors. Whether it fits any strategy depends on your goals, risk tolerance, and ability to monitor positions closely. Walnut is informational, not investment advice.
What is the difference between SRTY and TZA?
+
SRTY (ProShares UltraPro Short Russell2000) and TZA (Direxion Daily Small Cap Bear 3X) are near-identical competitors: both are -3x inverse ETFs targeting three times the opposite of the daily Russell 2000 return. They differ mainly in issuer (ProShares versus Direxion), fund size and liquidity, and small fee differences. TZA is often the larger and more heavily traded of the two. Both share the same daily-reset decay risk and are intended only for short-term use.
Who might use SRTY and how?
+
SRTY is typically used by active traders who expect U.S. small-cap stocks to fall in the near term, or by investors wanting a brief hedge against small-cap exposure during a market selloff. Because of the -3x leverage and daily reset, it is generally held for hours to a few days and monitored closely, with a clear exit plan. Holding it passively exposes you to compounding decay and the high expense ratio. Walnut is informational, not investment advice.
How do I compare SRTY 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. SRTY's figures are above; the full method is in Walnut's guide on how to compare ETFs.
