US PRE-MARKET MOVERS: MU, NIO, FRVO, MDT, NVS, HOOD

Here the items split cleanly along those lines. MU's strike threat over a bonus dispute is a labour headline, and past disputes of this kind at single facilities or subsidiaries have tended to be negotiating theatre that resolves without lasting supply impact, though memory-chip names trade with enough leverage to supply headlines that the tell is whether the dispute escalates past rhetoric into actual work stoppage. NIO's shallower loss with a revenue miss follows the established pattern for the China EV complex, where the market has historically rewarded margin discipline over top-line growth only when it persists across quarters. FRVO's power agreement with a hyperscaler extends a familiar theme in which utilities and power producers with contracted data-centre load have re-rated on each incremental deal, with the sustainability question being contract tenor and pricing rather than headline capacity. MDT's beat-and-raise and NVS's positive MS trial read are standard single-name catalysts, the former trading on guidance credibility, the latter on whether the comparative efficacy claim holds up against the existing standard of care. HOOD's upgrade is the least informative category, as single-firm rating changes without an estimate revision attached have tended to fade by the cash open.
