Hong Kong stocks fell for the third straight session on Monday, as the market's strong months-long rally showed signs of fatigue. Sentiment was also hurt by bearishness in mainland China markets, where blue chips had their worst day in two months amid worries about tighter regulation. The Hang Seng index dropped 0.2 percent to 23,919.46 points, while the Hong Kong China Enterprises Index lost 0.8 percent, to 10,338.12.
The Hang Seng is under increasing pressure from profit-taking, having climbed over 8 percent so far this year on the back of Wall Street bullishness and share purchases by mainland investors, including insurers. The gains had pushed it well into technically overbought territory, leaving it vulnerable to a pullback. Gao Ting, head of China strategy at UBS Securities, said regulators have set risk prevention as their main emphasis, reducing the chance of aggressive buying by insurers on the secondary market.
Still, "we expect insurers to be the main contributor of southbound trading this year," he said. Most sectors fell on Monday, with energy shares among the worst performers. Hong Kong Exchanges and Clearing Ltd (HKEX) fell 1.3 percent, after the city's stock exchange operator said its 2016 net profit fell 27 percent due to a decline in trading fees.
