On August 24, Hong Kong stocks came under heavy selling pressure as Alibaba's massive share placement rattled the market. All three major indices fell into the red. At the time of writing, the Hang Seng Index had dropped 511.11 points or 1.96% to 25,498.35; the Hang Seng Tech Index sank 175.04 points or 3.67% to 4,591.12; and the HSCEI slid 162.39 points or 1.88% to 8,471.95.

On the sector front, Alibaba's slump of over 9% dragged the entire tech complex lower, while semiconductor stocks also came under pressure. Bucking the downtrend, oil stocks advanced, gold miners rallied as bullion prices breached the US$4,600 mark, and select new-consumer names put in a standout performance.
