Chinese mainland investors’ fund flows into Hong Kong stocks have swung sharply, with HK$27.4 billion ($3.5 billion) sold on Tuesday after HK$29.7 billion bought the day before. The rapid in-and-out trades, mostly via large ETFs like the Tracker Fund of Hong Kong, suggest short-term trading rather than long-term positions, as investors seek hedging, liquidity, or bottom-fishing in sectors like tech and healthcare. The Hang Seng Index has fallen about 10% since January, prompting cautious and opportunistic ETF activity.(金十数据)
