On August 6, Lam Research fell 3.79% in regular trading, trading at $304.31/share, with turnover of $2.5 billion.

The semiconductor equipment sector showed internal divergence, with Applied Materials down 1.47%, MKS Instruments down 4.31%, and KLA Corporation down 0.66%, while ASML Holding rose 1.93%. The broader weakness among peers added further downside pressure on the stock.

Lam Research had previously surged over 23% in a single session after reporting fiscal Q4 results that comprehensively beat expectations — adjusted EPS of $1.82 exceeded the consensus estimate of $1.68 by 8.33%, revenue of $6.72 billion set a record high, and Q1 guidance of $7.70 billion to $8.50 billion in revenue with non-GAAP EPS of $2.00 to $2.30 far surpassed analyst expectations of $7.11 billion and $1.84, respectively. Following that sharp rally, the stock has been oscillating between profit-taking and technical recovery, with today's sector weakness extending the pullback.
