Other big winners so far this week are some of the so-called semicap shares — makers of the ultraprecise machines that turn silicon into actual semiconductors — with Lam Research and KLA Corp both racking up gains of about 10% on the week. Applied Materials is up about 8% this week.
Thematically speaking, both memory stocks like Sandisk and Micron as well as semicap shares like KLA have been part of the “buy the bottleneck” trade, in which investors buy companies they believe sit at key pinch points in the AI supply chain and therefore have pretty tremendous pricing power. Through that lens, the stocks’ bounce might reflect some additional excitement about the durability of the data center boom after Oracle’s results, which included a larger-than-expected capex number as well as sales guidances that was higher than Wall Street was forecasting.
But the bounce also may be the less interesting market phenomenon of mean reversion rearing its head, as these stocks were also some of the most beaten down in the S&P 500 last week, when Sandisk lost 17% and Lam lost about 15%, for example. So, some snapback may merely be a market reflex.
