SU Group’s Brutal Week Leaves $1 Line in Focus Before Monday Trade
SU Group Holdings Limited’s Nasdaq-listed Class A shares ended a holiday-shortened U.S. week under heavy pressure, closing at $1.02 on Friday, down 31.5% on the day, and then slipping to 98.02 cents after hours. The Hong Kong security-services company fell each trading day after the prior Friday close of $3.44, market data showed. That makes Monday the next test. Nasdaq trades regular hours from 9:30 a.m. to 4:00 p.m. ET on weekdays, and the exchange’s 2026 calendar shows May 25 was closed for Memorial Day and June 19 is the next scheduled U.S. holiday.
