US stocks open mixed as Dow drops 0.57%

The divergence between the Dow's decline and the Nasdaq's slight gain points to a market split, likely driven by sector rotation rather than a broad risk-off move. This matters for traders tracking index-level signals, as it suggests capital is favoring tech over industrials or other Dow-heavy sectors. The open question is whether this gap widens into a sustained trend or narrows as the session progresses, which would clarify whether the move reflects earnings-driven repositioning or broader macro caution.
