On July 8, Lam Research fell 3.2% in pre-market trading, trading at $315.99/share, with turnover of $6.74 million.

On the news front, President and CEO Timothy Archer exercised options and sold 30,000 shares at $390.01 per share on July 2, totaling approximately $11.7 million. The executive's large-scale disposal at elevated price levels continues to weigh on market sentiment.

Meanwhile, Samsung Electronics' quarterly results update raised doubts over the sustainability of the AI chip sales boom, triggering a global selloff across chip stocks. The semiconductor equipment sector remains broadly under pressure, with the Philadelphia Semiconductor Index having plunged 11% over two consecutive sessions in the prior week, and Lam Research accumulating over 15% in losses during that period. A brief technical rebound failed to sustain momentum.

Within the Semiconductor Equipment sector, Applied Materials fell 2.87%, KLA-Tencor fell 2.65%, Teradyne fell 3.13%, ASML fell 1.05%, and MKS Instruments fell 1.73%, reflecting continued sector-wide weakness.
