While artificial intelligence and semiconductor stocks have dominated market headlines this year, two of the best-performing U.S.-listed ETFs over the past month made their gains by betting against one of Wall Street’s biggest momentum names: Strategy Inc. (NASDAQ:MSTR).
• T-Rex 2X Inverse MSTR Daily Target ETF shares are consolidating. What should traders watch with MSTZ?
The T-Rex 2X Inverse MSTR Daily Target ETF (BATS:MSTZ) and the Defiance Daily Target 2X Short MSTR ETF (NASDAQ:SMST) surged around 200% over the past month, making them the top-performing ETFs during the period. The outsized gains came as Strategy shares pulled back sharply after an extended rally, giving a boost to leveraged inverse products designed to profit from declines in the Bitcoin (BTC) proxy.
Why Short Strategy ETFs Soared
Strategy has become one of the market’s most closely watched stocks because of its aggressive Bitcoin accumulation strategy. The company holds hundreds of thousands of bitcoins on its balance sheet, making its shares highly sensitive to moves in the cryptocurrency.
After months of strong gains fueled by Bitcoin’s rally and continued institutional interest in digital assets, Strategy stock reversed course in June, triggering an outsized move in inverse leveraged ETFs.
MSTZ and SMST each seek to deliver 200% of the inverse (-2x) of Strategy’s daily share price performance. Because they reset daily, the funds are primarily designed for short-term tactical trading rather than long-term investing.
June’s Biggest ETF Winners
The two funds significantly outpaced ETFs focused on AI, semiconductors and technology, such as Global X Artificial Intelligence & Technology ETF (NASDAQ:AIQ), Global X Robotics and Artificial Intelligence ETF (NASDAQ:BOTZ), VanEck Semiconductor ETF (NASDAQ:SMH), and iShares Semiconductor ETF (NASDAQ:SOXX) segments that have otherwise dominated ETF inflows and performance rankings throughout 2026.
Their gains underscore how quickly sentiment can shift in single-stock leveraged ETFs, where daily compounding can amplify returns during sustained directional moves.
A Growing Corner of the ETF Market
The strong performance also highlights the rapid expansion of the single-stock ETF market. Asset managers have rolled out leveraged and inverse ETFs tied to high-profile companies such as Nvidia Corp (NASDAQ:NVDA), Tesla Inc (NASDAQ:TSLA), Palantir Technologies Inc (NASDAQ:PLTR), Oracle Corp (NASDAQ:ORCL) and Strategy, allowing traders to express bullish or bearish views without using margin or options.
Unlike diversified index ETFs, these products are intended for active traders seeking to capitalize on short-term price swings. Their daily reset mechanism means returns over periods longer than one day can differ significantly from simply doubling the inverse of the stock’s cumulative performance, particularly in volatile markets.
June’s leaderboard illustrates that even in a year defined by AI enthusiasm, the market’s biggest ETF winners can emerge from entirely different themes. Rather than riding the semiconductor boom or mega-cap technology rally, investors who correctly anticipated a reversal in Strategy shares captured some of the strongest gains available in the ETF market.
