US stock futures close mixed: Nasdaq 100 down 2.52%, Russell 2000 up 0.97%

The split between Nasdaq 100 futures and Russell 2000 futures points to a rotation rather than a broad risk-off move, with large-cap growth absorbing the selling while smaller caps held up. That divergence matters for anyone tracking where equity risk appetite actually sits, since a tech-led drawdown that spares small caps tells a different story than a uniform decline. Whether this gap persists into the next session, or narrows as one side catches up, is the open question worth watching.
