Stock Plunges to 108th in Daily Trading Activity Amid 30.38% Volume Drop

On September 18, 2025, , , . This marked a significant drop in liquidity compared to recent sessions, raising questions about short-term investor positioning.

Analysts noted that the reduced volume could reflect a temporary consolidation phase rather than a structural shift. With limited catalysts in the near term, the stock’s performance appears to hinge on broader market sentiment and sector-specific dynamics. The absence of material news in the immediate term suggests the decline may be attributed to profit-taking or rebalancing by institutional investors.

To run this back-test robustly, I need to confirm a few practical details. First, the universe must define the scope of daily screening—whether it includes all and NASDAQ-listed stocks or narrows to a specific index like the S&P 1500. Second, weighting methodology and execution timing require clarity: should the 500 names be equally weighted daily, and will trades occur open-to-close or open-to-open? Additionally, assumptions about slippage and commission costs must be established. Finally, a benchmark such as SPY could provide context for evaluating the strategy’s risk-return profile. Once these parameters are confirmed, the back-test can proceed with historical data from January 1, 2022, to the present.
