On Semiconductor Shares Fall 2.1% as 50.8% Volume Spike to $480M Pushes Stock to 211th in Market Activity

On Semiconductor (ON) closed 2.10% lower on Sept. 23, 2025, despite a 50.8% surge in trading volume to $0.48 billion, ranking the stock 211th in market activity. The mixed performance highlights divergent investor sentiment amid limited direct news catalysts for the chipmaker.

While no company-specific announcements were reported for ON during the session, broader market dynamics and sector positioning likely influenced the stock’s trajectory. The absence of earnings updates, corporate actions, or industry-specific events in the reviewed news further underscores the lack of immediate directional guidance for the stock.

To run this back-test for you I need to pin down a few practical details: 1. Market universe • Should I restrict the “top-500 by volume” list to U.S. listed common stocks only (the usual default), or include ADRs, ETFs, etc.? 2. Re-balancing mechanics • Do you want the portfolio re-formed every trading day, with every position fully closed the next day (i.e., a one-day holding period and 100% turnover)? 3. Weighting & cash handling • Equal-weight each name, or volume-weight / market-cap-weight? • Assume zero transaction costs and perfect liquidity, or add explicit costs/slippage? 4. Benchmark (optional) • Any benchmark you’d like the returns compared against (e.g., SPY, equal-weighted universe)? Once I have this clarified I’ll generate the data-retrieval plan and run the automated back-test.
