On July 28, Lam Research fell 3.13% overnight, trading at $282.49/share, with turnover of $2.7997 million.

The decline was driven by a broad selloff in memory stocks that transmitted negative sentiment to the semiconductor equipment sector. Micron Technology fell 5.82%, SK Hynix dropped 6.83%, and SanDisk declined 7.10%, triggering sector-wide weakness across equipment names. ASML fell 2.07%, Applied Materials dropped 2.49%, KLA-Tencor declined 2.83%, and Amkor Technology slid 8.75%.

The selling pressure comes ahead of Lam Research's quarterly earnings report scheduled for July 29 after market close. Consensus expects EPS of $1.69, a notable increase from $1.47 in the prior quarter. Pre-earnings positioning has intensified capital flows and amplified volatility. Despite multiple investment banks raising target prices in July — UBS to $435, Stifel to $425, Mizuho to $400, and Evercore ISI to $355 — the broader sector downdraft and earnings uncertainty have dominated near-term price action.
