On September 28, Lam Research declined 3.14% overnight, trading at 305.64 USD/share, with turnover of $4.41 million.

The drop coincided with broad-based weakness across the semiconductor equipment sector, triggered by the Federal Reserve's unanimous 25-basis-point rate hike to 3.75%–4.00% — the first increase in three years — which pushed the 10-year Treasury yield above 5%, intensifying selling pressure on high-valuation technology stocks. Pre-holiday risk-off sentiment further weighed on the sector, as market participants moved to lock in gains accumulated during the first half, when some semiconductor names had more than doubled.

Within the Semiconductor Equipment sector, AXT Inc fell 4.35%, Teradyne dropped 3.09%, Applied Materials declined 2.88%, KLA Corporation lost 2.72%, and ASML slid 1.87%. Analysts noted that while short-term sentiment remains subdued, global semiconductor equipment spending continues to expand, with second-quarter shipments rising 23% year-over-year to $40.53 billion, and the post-holiday recovery probability historically remains elevated.
