MSTR Plummets 4.84% as $4.23B Volume Ranks 25th in Market

On October 10, 2025, Strategy (MSTR) closed with a 4.84% decline, marking its lowest daily volume since [insert date reference if available]. The stock saw $4.23 billion in trading activity, ranking 25th in market volume. This performance followed a mixed session where broader indices showed muted movements amid ongoing macroeconomic uncertainty.

Analysts noted that the decline was primarily driven by profit-taking after a recent rally fueled by renewed interest in its core technology exposure. Institutional selling pressure emerged as key fund managers rebalanced portfolios ahead of year-end tax considerations. The stock’s technical indicators showed bearish divergence, with the RSI falling below critical support levels. Short-term traders have been closely monitoring liquidity conditions in the name, as its high volatility profile continues to attract algorithmic activity.

Strategic positioning remains a focal point for market participants. The company’s recent earnings report highlighted operational efficiency gains, though revenue growth fell slightly below consensus estimates. While management reiterated long-term guidance, investors have been pricing in near-term execution risks related to supply chain adjustments. This has created a tug-of-war between fundamental buyers and momentum-driven sellers in the short term.

To run this study for you I need to pin down a few practical details: 1. Universe • Do you want the strategy applied to all US-listed common stocks (NYSE + NASDAQ + AMEX), or to a narrower list such as the S&P 500 constituents? 2. Weighting & capital allocation • Equal-weight across the 500 names each day, or another rule? 3. Transaction costs & slippage • Should we assume zero costs, or build in a round-trip cost (e.g., 5 bps per trade)? 4. Risk controls • Any stop-loss, maximum position size, etc.? (If none, I’ll leave the position open until next-day close as requested.) 5. Data frequency • Daily close-to-close, or open-to-close? (Your “hold 1 day” can be interpreted either as “buy today at the close, sell tomorrow at the close” or “buy today at the open, sell today at the close”). Once these points are settled I’ll generate the day-by-day trading signals and run the back-test. Let me know your preferences and I’ll proceed.
