Coherent's 9.19% Plunge on $430M Volume Propels It to 293rd in Daily Trading Activity Amid Strategic Shifts and Sector Headwinds

Coherent (COHR) closed at a 9.19% decline on October 10, 2025, with a trading volume of $430 million, ranking it 293rd in market activity for the day. The stock's performance was influenced by strategic shifts in its semiconductor laser division and evolving demand dynamics in industrial applications.

Recent operational adjustments, including the consolidation of manufacturing facilities in Europe, have raised investor concerns about short-term cost pressures. Analysts noted that the company's pivot toward higher-margin photonics solutions for medical devices has created uncertainty among traditional industrial clients, contributing to the sell-off.

Market participants also highlighted broader sector trends, with reduced capital expenditures in semiconductor fabrication equipment affecting downstream demand for Coherent's precision measurement tools. While the company reaffirmed its long-term growth strategy during a recent earnings call, near-term revenue visibility remains constrained by macroeconomic headwinds.

To set up an objective, reproducible back-test, I need to pin down a few practical details: 1. Market universe—Do you want to scan the entire U.S. listed equity universe (NYSE + NASDAQ + AMEX) every day, or would a well-defined subset (e.g., today’s S&P 500 constituents) be acceptable? 2. “Top 500 by daily trading volume”—Rank using the previous day’s total share volume, correct? 3. Trade price & holding rules—Entry at today’s close, exit at tomorrow’s close (1-day holding period)? 4. Back-test window—Start: 2022-01-03, End: 2025-10-10. Once these points are confirmed, I can proceed with data collection and execution.
