HONG KONG, July 27 (Reuters) - Asia’s stocks fell to fresh seven-month troughs on Tuesday, led by a third straight session of heavy selling of Chinese internet giants, while bond and currency markets clung to tight ranges ahead of the Federal Reserve policy meeting. MSCI’s broadest index of Asia-Pacific shares outside Japan fell 0.97% to its lowest level since December, having slid 2.45% the previous day. The Hong Kong benchmark fell 2.84% on Tuesday, its third day of declines, with the Hang Seng Tech index down 6.46% to its lowest since its inception in July 2020. It has fallen around 14% in three days and has lost 41% from a February peak. Big decliners included Meituan and Alibaba , whose shares fell 12.7% and 5.5% respectively. Both were down for the third successive day with investors expecting the companies’ food delivery arms to be affected by new regulations guaranteeing workers above minimum pay. In onshore markets, Chinese bluechips dropped sharply in afternoon trading, falling 2.93% after closing at their lowest since December on Monday thanks to regulatory crackdowns in the education and property sectors. “The market seems to be uncertain whether there will be more policy changes for fintech, social media platforms, delivery platforms and ride hailing platforms,” said Iris Pang, chief economist for Greater China at ING. “Each has their own issue and faces different regulatory actions, so the market is looking for ‘which technology subsector will be next?’” Elsewhere in Asia, investors were more optimistic, with Japan’s Nikkei rising 0.49%, and Australian shares closing up 0.46%.

The next couple of days are going to be monumental as everyone tries to figure out how strong corporate fundamentals are at the moment and in what context that is happening in terms of the economic outlook and policy settings,” said Kyle Rodda, market analyst at IG Markets.
