The S&P 500 rose 1.15% over the same period, so the stock lagged the benchmark by about 9.39 percentage points. The move was a fade from early strength: Monday opened at $346.875 and the week’s high was $351.365, but selling resumed from Tuesday and the stock slipped below $320 on Thursday, hitting a low of $316.01 on Friday before a small bounce into the close. Weekly amplitude was 10.19%, with trading volume slightly below the median. ## Key Events The week’s narrative centred on strong AI chip-equipment demand signals colliding with early-quarter profit-taking. BofA named Lam Research among five AI chip stocks to buy for Q4, while Morgan Stanley said it expects the company to guide above $9 billion for the December quarter. On Tuesday the shares dropped 3.87%, and pre-market quotes pointed to a decline of more than 3%, in line with weakness in ASML. Friday’s session ended lower but Lam Research still outperformed some peers. Jim Cramer flagged chipmakers as a key test in the coming earnings season. There was no company-specific earnings release or major regulatory news during the week. ## Analyst Ratings Across 35 institutions covering Lam Research, 25 rate it buy, 4 rate it overweight, 6 rate it hold, and none rate it underweight or sell. The consensus rating is strong buy, with a consensus target price of $375.65, implying about 17.82% upside from the current price. Target prices range from $290 to $500, a wide spread. Within the semiconductor materials and equipment industry of 32 companies, Lam Research ranks third by rating, near the top of the group. ## The Week Ahead Earnings season moves into a denser phase. US CPI and core CPI land on Wednesday, 14 October, and the data will shape expectations for the Fed’s rate path, which matters for valuation-sensitive semiconductor names. Lam Research’s own quarterly report is scheduled for after the close on Wednesday, 21 October, with consensus estimates at $2.1768 EPS and $8.134 billion in revenue for the first quarter of fiscal 2027. Whether Morgan Stanley’s above-$9 billion guidance expectation holds up will be the next key test. ## In Short Lam Research pulled back sharply this week despite a still-supportive AI demand backdrop, lagging the S&P 500 by nearly 9.4 percentage points. The sell-off sits alongside a strong-buy consensus and a target price roughly 18% above spot, while the latest session’s money flow showed large-lot money turning net seller. Valuation is not cheap at about 54.9x P/E and 32x P/B. The path forward depends on how the CPI print affects sector valuation and whether the 21 October earnings release can justify the relatively upbeat brokerage view. *This article is generated by LongbridgeAI from market data, for information only and not investment advice.* ### Related Stocks - [LRCX.US](https://longbridge.com/en/quote/LRCX.US.md) - [LRCU.US](https://longbridge.com/en/quote/LRCU.US.md) - [SOXL.US](https://longbridge.com/en/quote/SOXL.US.md) ## Related News & Research - [Anthropic IPO Hype Meets AI Spending Risks: 6 ETFs to Watch Beyond Semiconductors](https://longbridge.com/en/news/301430757.md) - [Jim Cramer Calls Kulicke & Soffa ‘Terrific,’ But Prefers These 2 Chip Equipment Stocks](https://longbridge.com/en/news/301405025.md) - [SOXL ETF Shares Rise 5% After Key Trading Signal](https://longbridge.com/en/news/301753497.md) - [Lam Research Corp.
