US Stocks Close Mixed; SanDisk Falls 5.98%, Micron Drops 3.65%

The split between a firmer Dow and a weaker Nasdaq, alongside sharp declines in memory-linked names like SanDisk and Micron, points to pressure concentrated in semiconductors rather than broad risk-off selling. That distinction matters because it suggests stock-specific or sector-specific drivers are at work, not a market-wide move. Meta's gain while chip names fell reinforces that dispersion. Whether the weakness in memory and chip stocks continues to diverge from the broader index is the open question.
