Meta shares rise for a second straight day as new AI model family impresses

Stocks were lower across Wall Street Tuesday afternoon as memory and parts of the AI buildout trade struggled, extending a drawdown in semiconductors. The iShares Semiconductor ETF and VanEck Semiconductor ETF were on pace for a sixth straight losing day, their longest streak since May 2025. Micron, SK Hynix and other memory names fell sharply after Chinese rival CXMT said it made progress on a more efficient way to produce memory chips. Not all tech lagged: Meta Platforms rose nearly 3% for a second straight day, supported by enthusiasm for its new AI model family, Muse Wonder, with a more advanced Muse Wonder Full. Wells Fargo also reported Meta reached the “AI frontier” with the Full version.
