Jim Cramer Says It's Not Too Late to Buy Data Center Winners

CNBC columnist Jim Cramer told Investing Club subscribers that "it's not too late" to buy stocks tied to AI infrastructure and data centers, framing the group as a continuing opportunity. CNBC reports the Roundhill Memory ETF (symbol DRAM) recorded inflows of more than $5 billion over a month and $1.1 billion on one Thursday, which Cramer cited as evidence of investor demand. The CNBC coverage lists the ETF's core holdings as SK Hynix, Micron, Samsung, Sandisk, Seagate, Kioxia, and Western Digital. In the same coverage Cramer calls Modine Manufacturing "a buy" and compares it favorably to data center suppliers like Vertiv and Eaton, while noting it looks better than Carrier because of Carrier's residential exposure. A related CNBC segment on May 8 noted technology led the S&P 500 for the week, with the sector up 7% and the overall index up 2.3%.

Investor attention focused on memory and data center suppliers often reflects expectations of elevated demand for DRAM and NAND from hyperscalers and AI workloads. Rapid ETF inflows into memory-focused funds are an observable market signal; industry reporting connects those flows to a so-called memory supercycle. Companies that supply servers, power, cooling, and storage can experience correlated sentiment-driven price moves when capital rotates into infrastructure themes.

Industry observers note that large, concentrated inflows can amplify short-term price action for suppliers and related component makers. For practitioners, that pattern typically translates into tighter supplier allocation, longer lead times for system components, and windfall revenue quarters for cycle beneficiaries. Coverage that highlights smaller, less-covered suppliers, as Cramer did with Modine, often reflects investors hunting for leveraged exposure beyond the largest OEMs and chipmakers.
