US stocks open mixed: energy sector down 2.29%, tech down 1.29%, financials up 0.41%

The split at the open is the story: energy and tech selling off together while financials hold small gains points to sector rotation rather than a broad risk-off move. That divergence matters for anyone tracking where leadership sits in the session, especially since a modest financials gain against a steep energy drop suggests capital is repositioning rather than exiting. Whether financials can hold their advance as energy and tech extend losses is the open question worth watching.
