Venture Global also made headlines, with its shares climbing over 7% following a strong first-quarter earnings performance. In addition, Aramark experienced a 2% uptick after surpassing second-quarter estimates, driven by a notable 15% revenue increase.

Vestis also made gains, rising on a raised outlook despite a less-than-stellar second-quarter earnings report. Investors responded positively to strong bookings at Vishay Precision Group, which saw a stock rise of more than 25%. However, not all small-cap companies fared well; ZoomInfo tumbled 27% due to a miss on revenue guidance, contributing to a general trend of declines for several small-cap stocks.
