At a glance: stocks gapping down premarket

S&P 500 futures were trading lower ahead of the U.S. open as investors reacted to growing fears the U.S.-Iran ceasefire could collapse, pushing markets into a risk‑off tone. The premarket saw a string of stocks gapping down, with several small‑caps plunging double digits (Microvast -37.1%, ZoomInfo -34.1%, Power Solutions -31.5%) and broader weakness reflected in S&P futures (~7,381.53, -0.42%). The moves highlight heightened volatility and narrow market leadership, with premarket losers concentrated in select names and the index sliding modestly on geopolitical concerns.
