US stocks open mixed as memory chip shares slide; Starbucks gains, Chipotle drops

The memory-chip slide looks like a targeted move rather than broad tech weakness, since the Dow and S&P still edged higher while the Nasdaq held roughly flat. That divergence matters because memory names are tied to the AI and data-center buildout, so their underperformance can signal shifting expectations for that demand even when headline indices look calm. The Starbucks-Chipotle pair is a reminder that single-stock moves can rest on unconfirmed deal chatter rather than fundamentals. Whether the memory weakness persists or broadens beyond that group is the open question.
