Howmet Shares Fall 0.51% Amid Executive Sell-Off, 330th in Daily Trading Volume

On September 2nd, 2025, Howmet Aerospace (HWM) closed with a 0.51% decline, trading at $174 per share. The stock accounted for $0.34 billion in volume, ranking 330th among active equities on the day.

Insider selling activity has drawn attention as key executives liquidated significant stakes. Over the past year, Executive Chairman John Plant sold $126 million in shares at $157 apiece, while Executive VP Lola Lin offloaded $2.4 million in the last three months. Notably, no insider purchases were recorded in the past 12 months, raising questions about management’s confidence in the stock’s valuation. Despite these sales, insiders still hold $642 million in shares, representing 0.9% of the company.

While insider transactions are not definitive indicators of long-term performance, the absence of buying activity contrasts with the company’s reported profit growth. Analysts caution that prolonged selling—especially below current prices—may signal undervaluation concerns. However, the relatively small scale of individual sales (e.g., Plant’s $126 million sale accounted for just 22% of his holdings) suggests a measured approach rather than panic divestment.

Backtesting results from Simply Wall St indicate mixed signals for HWM. The firm highlights two warning signs for investors, though it notes Howmet’s strong profitability and insider ownership as positives. The analysis excludes recent price-sensitive disclosures and derivative transactions, emphasizing the need for further due diligence.
