Amphenol Shares Climb 1.69% on 110th-Ranked $0.75B Volume Amid $1B Trexon Acquisition to Expand Defense Segment

On August 18, 2025, Amphenol (APH) rose 1.69% with a trading volume of $0.75 billion, ranking 110th in market activity. Institutional investors, including Vanguard Group and Bank of America, significantly increased holdings in the company during recent quarters, reflecting confidence in its growth trajectory. Horizon Investments, however, reduced its stake by 8% in Q1, now holding 51,605 shares valued at $3.4 million.

The company announced a $1 billion cash acquisition of Trexon, a defense-focused interconnect solutions provider, to bolster its Harsh Environment Solutions segment. The deal, expected to close in Q4 2025, is projected to enhance earnings per share in the first year post-merger. Management highlighted Trexon’s high-reliability cable assemblies as a strategic complement to Amphenol’s existing defense offerings.

Amphenol’s Q1 earnings report underscored robust performance, with $0.81 per share (beating estimates by $0.15) and revenue surging 56.5% year-over-year to $5.65 billion. The firm also declared a quarterly dividend of $0.165 per share, maintaining a payout ratio of 26.29%. Analysts adjusted price targets, with Bank of America raising its estimate to $120 and UBS Group affirming a “buy” rating. However, insider sales, including 286,000 shares by Luc Walter and 40,000 by VP Michael Ivas, signaled caution among executives.

A backtest of a strategy purchasing top 500 volume stocks and holding for one day from 2022 to 2025 showed a 0.98% average daily return, with a cumulative 31.52% gain over 365 days. This highlights the potential for short-term momentum capture but underscores risks tied to market volatility and timing.
