US semiconductor index rebounds 1.2% to near 9,377, reversing early drop below 9,039

The significance here is less the 1.2% gain than the intraday shape: a session that opened below 9,039 and closed near its high suggests buyers stepped in aggressively rather than the move being a drift higher. For a sector as rate- and cycle-sensitive as semis, that kind of reversal often reflects positioning unwinds more than fresh conviction. Whether the index holds above the prior opening level in coming sessions is the open question; a quick retest of the early low would undercut the turnaround narrative.
