Coherent’s 0.39% Rise on $290M Volume Propels It to 370th Market Activity Rank

Coherent (COHR) rose 0.39% on Sept. 26, with a trading volume of $290 million, ranking 370th in market activity. The stock’s performance appears tied to selective technical adjustments in its sector, though broader market dynamics showed limited directional bias. Analysts noted muted volatility amid mixed sector rotation patterns.

To execute a precise back-test for Coherent’s strategy, several parameters require clarification: the stock universe defaults to NYSE and NASDAQ-listed common shares (excluding OTC and foreign ADRs). Daily trading volume rankings will reference the prior day’s data. For intraday holds, entry is set at market open using yesterday’s rankings, with exits at day’s close. Overnight holds involve buying at close and selling the following day. Position weighting defaults to equal allocation across 500 stocks, rebalanced daily. Transaction costs and slippage are excluded unless specified.

Requests for adjustments to these parameters should be submitted promptly to initiate data collection and back-testing. The methodology emphasizes consistency in execution timing and weighting to isolate the impact of volume-based ranking signals on short-term performance.
