US stocks preview: storage names jump, KLA up 7.32%, CPI ahead

The storage-led rally, with KLA's outsized move absent any company-specific catalyst, suggests sector rotation or positioning ahead of the CPI print rather than fundamental repricing. This divergence—small caps up while large indexes fell—hints at a broadening market under the surface, but the real test is whether inflation data validates the current risk appetite. The open question is whether Friday's core CPI at 2.5% sustains this selective buying or triggers a reversal if it surprises, as the tape's reliance on macro data remains acute.
