US Stock Futures Close Higher; Nasdaq 100 Futures Jump 2.82%

The gap between Nasdaq 100 futures and the Dow captures how narrowly this rally is built: gains are concentrated in the growth-heavy end of the index while small caps barely moved, which points to a handful of large technology names doing the heavy lifting rather than broad-based risk appetite. The timing is also notable, with the move arriving in the final hours of the session rather than building through the day. Whether that late-session strength carries into the next open, or fades as quickly as it appeared, is the open question.
