US markets opened mixed today with broad weakness across major indices.

$SPX down 0.22% to 7,801.77
$DJI off 0.66% to 51,179.87
$COMP slipped 0.22% to 27,538.69
$RUT hit hardest, down 1.31% to 2,793.20

VIX ticked up 3.25% to 15.57 — still subdued but showing modest caution.

Sector rotation clear: Healthcare leading at +0.80% while Industrials lagging badly at -2.31%. Small caps underperforming large caps suggests risk-off positioning.

Nothing dramatic yet, but the Russell weakness and Industrial selloff hint at concerns around economic momentum or rate expectations. Watch if this broadens or fades by close.
