The benchmark snapped a six-session winning streak as gains tied to Beijing's latest market-opening steps faded and investors turned cautious ahead of China's trade data.
Hong Kong stocks weakened on Tuesday, with the Hang Seng Index falling 0.5%, or 123 points, to 25,885 and ending a six-session run of gains. Early optimism over Beijing's latest measures to strengthen Hong Kong's role as an international financial hub faded as selling emerged in heavyweight technology and financial stocks. Investors also locked in profits amid lingering caution over China's economic outlook, corporate earnings and trade figures due later this week.
