As HK stocks closed on May 20, the broader market trended weaker amid soaring global long-term bond yields and developments among tech giants. The three major indices showed divergent performance, with the Hang Seng Tech Index bucking the trend to edge up 0.34%. On the trading floor, the semiconductor sector exploded collectively under multiple positive catalysts, with SMIC recording over HK$18.8 billion in turnover, while HUA HONG SEMI and GigaDevice both posted double-digit gains. Additionally, Alibaba's release of its self-developed AI chip spurred activity in computing power concepts, whereas gold resource stocks and certain tech majority stake stocks generally pulled back under pressure from the high-interest-rate environment
