U.S. Memory Stocks, ETFs Jump on July 21

AI Market Summary
U.S. memory and storage-linked equities rallied sharply on July 21, with broad gains across Micron, Western Digital, Seagate, and the Roundhill Memory ETF, alongside strength in SK Hynix's ADR. The synchronized move suggests a sector-wide repricing, likely reflecting improved expectations for memory demand and pricing power. Near-term, this can lift semiconductor risk appetite and increase volatility in memory-exposed names and related ETFs.
