Coherent Gains 1.91% Amid 67.7% Volume Drop Ranks 107th as $400M Aerospace Sale Fuels Sector Consolidation

On August 15, 2025, Coherent (COHR) closed with a 1.91% gain despite a 67.7% drop in trading volume to $0.84 billion, ranking 107th in market activity. This modest price increase occurred against the backdrop of a significant corporate transaction involving its Aerospace and Defense segment.

Weil, a law firm, is advising Advent on a $400 million acquisition of Coherent’s Aerospace and Defense business, which specializes in optical and laser systems for defense applications. The segment employs approximately 550 people across 10 locations. Post-transaction, the acquired unit will operate under a new name to be announced later. The deal is expected to finalize in Q3 2025, pending standard closing conditions. This strategic divestiture may reshape Coherent’s operational focus while providing immediate liquidity.

The transaction highlights the ongoing trend of specialized technology assets being targeted for sector-specific consolidation. Analysts note that such deals often reflect broader industry dynamics rather than immediate earnings impacts, though long-term restructuring costs and operational shifts could influence investor sentiment.

A strategy of buying the top 500 stocks by daily trading volume and holding for one day from 2022 to present yielded a 0.98% average return per trade, with a cumulative total return of 37.61%. While the approach demonstrated stability, the results underscored the conservative nature of volume-driven trading compared to higher-risk alternatives.
