A batch of small-cap names saw outsized premarket moves Monday morning, though volume remained thin across the board. BIYA led the gainers, up 6.2% at 7:25 a.m. ET. GVH rose 4.8%, ADVB added 3.5%, and SDOT climbed 2.9%. No company-specific news had crossed the tape by the time of the moves, leaving the action in the hands of retail order flow and low-float mechanics. Traders said the moves were unlikely to hold through the open without a catalyst, given the lack of volume behind them. The broader market was flat. S&P 500 futures ticked up 0.1% ahead of a quiet calendar that includes no major economic data or Fed speakers before the afternoon.
