On July 28, Lam Research fell 5.23% in regular trading, trading at 273.25 USD/share, with turnover of $189 million. The decline came as a broad sell-off in memory stocks continued to transmit negative sentiment across the semiconductor equipment sector ahead of the company's quarterly earnings report.

On the news front, memory stocks suffered sharp losses, with Micron Technology down 5.82%, SK Hynix down 6.83%, and SanDisk plunging over 11%. The weakness cascaded into the equipment space, with ASML Holding down 4.59%, Applied Materials down 5.61%, KLA-Tencor down 5.17%, and Amkor Technology plummeting 20.29%. Lam Research is scheduled to report quarterly results on July 29 after market close, with consensus EPS estimates at $1.69, up meaningfully from $1.47 in the prior quarter. Pre-earnings capital repositioning is further amplifying short-term volatility.
