Renaissance Large Cap Growth Strategy stated the following regarding Lam Research Corporation (NASDAQ:LRCX) in its Q3 2026 investor letter

"Other large detractors in the third quarter were Applied Materials (AMAT) and Lam Research Corporation (NASDAQ:LRCX). Like KLA, both stocks were negatively impacted from the rotation out of AI-related stocks as investors tried to ascertain the potential fallout from the aftermath of the Situational Awareness hedge fund implosion at the end of July. Somewhat predictably, the best performing stocks in the first half of 2026 experienced some of the worst performances in the third quarter, as investors refocused on the economics and return potential from the incredibly high levels of AI capex investments thus far."
