US Memory-Chip Stocks Fall Premarket; SK Hynix Down About 6%

The synchronized drop across memory names suggests a sector-wide repricing rather than a company-specific issue, with SK Hynix's steeper decline pointing to particular pressure on the Korean memory complex. TSMC's smaller move after reporting earnings implies the weakness is concentrated in memory rather than logic chips, a distinction worth watching as the session develops. Whether this reflects a durable shift in memory sentiment or a single-session reaction is the open question.
