HONG KONG — Hong Kong’s stock market carried the torch of China’s rally on Wednesday, marking the biggest single-day jump since March 2022 while mainland exchanges were closed for an extended holiday.

The Hang Seng Index gained more than 7% from the previous trading day in the afternoon, before closing up 6.2% at 22,443.73. The benchmark index was propelled by companies that are expected to benefit from Chinese authorities’ recent blast of economic stimulus, aimed at overcoming the effects of a relentless property crisis.
