On August 14, Lam Research fell 3.03% in regular trading, trading at $327.04/share, with turnover of $1.448 billion. The decline came as the semiconductor equipment sector experienced broad-based selling pressure.

On the news front, the company announced plans to invest over $3 billion over the next five years to expand its global research and development lab network, with experiment capacity expected to increase by more than 50%, aimed at accelerating semiconductor manufacturing innovation in the AI era. However, the stock had accumulated gains exceeding 10% over the prior three trading sessions following a Bernstein price target upgrade to $385 from $360, and the positive long-term capital expenditure signal was insufficient to offset near-term profit-taking momentum amid sector-wide weakness.

Within the Semiconductor Equipment sector, Applied Materials fell 5.68%, KLA Corporation fell 3.94%, and ASML Holding fell 1.46%, while AXT Inc rose 2.26% and Aehr Test gained 6.67%. The broad sector pullback amplified selling pressure on Lam Research as investors locked in recent gains.
