The Hang Seng Index rose 0.4%, or 107 points, to 25,152 on Tuesday, extending its winning streak to three sessions. Renewed strength in artificial-intelligence and semiconductor stocks, combined with lower oil prices, improved risk appetite. Hong Kong technology shares followed a positive lead from Wall Street as investors monitored developments before the expected meeting between US President Donald Trump and Chinese President Xi Jinping later this week. The city’s IPO market also remained active: Ligent Technologies was scheduled to begin trading Tuesday at an IPO price of up to HK$32.96 per share, while RoboTechnik, Kinwong Electronic, Red Avenue New Materials and Direct Drive Tech were seeking to raise up to US$1.83 billion combined.
