On September 10, Lam Research fell 3.01% in pre-market trading, trading at $306.32/share, with turnover of $4.4932 million, extending a 1.43% decline in the prior regular session.

On the news front, company director Bethany Mayer filed a Form 144 restricted stock sale statement, disclosing plans to sell 9,557 shares of Class A common stock valued at approximately $3.008 million. The shares originated from multiple vesting tranches of restricted stock units. Insider selling disclosures often weigh on near-term sentiment, particularly amid a fragile market backdrop.

Meanwhile, the semiconductor equipment sector saw broad-based selling pressure. Applied Materials fell 2.46%, ASML declined 1.78%, KLA Corporation dropped 2.80%, Teradyne slid 2.79%, and AXT fell 3.47%. The sector downturn was driven by a confluence of macro headwinds, including rising U.S. Treasury yields fueled by hawkish Federal Reserve rhetoric, renewed Middle East geopolitical tensions pushing oil prices higher, and a broader rotation out of high-valuation growth names into defensive sectors. These forces amplified individual stock declines across the equipment space.
