Lam Research (LRCX) climbed 8.2% on Friday, November 6, 2026, a day after the chip equipment maker’s board signed off on a $25 billion share repurchase authorization. The Lam Research buyback news followed a 16.4% plunge in the prior session and helped the stock close at $200.44, while the S&P 500 added just 0.3%.
Buyback Size Relative to Market Value
At the November 6 closing market value of $251 billion, the new authorization represents roughly 10% of the company. The board also declared a quarterly dividend of $0.33 per share.
The new program is sizable compared with recent spending. On the October 21 earnings call, management said Lam repurchased about $1 billion of its shares in the September quarter. At that time, $3 billion remained on the prior board-authorized program. Management also noted that a share repurchase arrangement started in the September quarter would carry into the December quarter.
Peer and Sector Performance
Lam’s advance stood out even as chip stocks broadly moved higher. All five companies on its peer list gained on November 6. Only MKS rose more, with an 8.7% increase. Applied Materials added 4.2%. The technology sector fund XLK gained 1.5%, and the Nasdaq Composite rose 1.1%.
A news report that day said the buyback sparked Lam’s rally after a sharp sell-off in chip stocks and that the company was leading an AI-related rebound.
Context: A Steep Monthly Decline
From October 8 to November 6, Lam shares fell 37.5%, while the S&P 500 declined 4.9%. An 8.2% single-day gain is not out of character for the stock: Lam had six sessions with moves of that size or larger over the prior 365 days. The most recent was the 16.4% drop on November 5, the session before the rebound.
The November 6 close of $200.44 is less than half the stock’s highest close over the past year, $433.33 on June 30, 2026. Its lowest close in that period was $139.59 on November 20, 2025. Over twelve months, Lam still returned 22.0%, compared with 9.8% for the S&P 500. The stock trades at 9.6 times trailing twelve-month sales, versus 3.1 times for the S&P 500.
What to Watch
Lam is scheduled to report its December-quarter results, fiscal Q2 2027, in January 2027. The amount the company spends on its own shares during that quarter is the figure to watch.
