Event-driven small/mid-caps dominated early gainers; dilution and guidance cuts pressured losers.
A cluster of small- and mid-caps led pre-market gainers on deal headlines and upbeat updates, while several prior high-beta winners slid after guidance tweaks and secondary sales. Traders scanned top-volume lists for repeatable catalysts and liquidity. The bias favored event-driven names with news that can survive the first pullback to VWAP. On the downside, capital-raise dilution and margin commentary weighed. With indices hovering near records, relative-strength persistence and opening-range breaks are emphasized. ETF flows and index-arb programs may amplify the first-hour moves across themes.
