Kweichow Moutai Co investors are selling their shares at the fastest pace in more than two years, a warning for a market that owes much of its rally to a handful of large caps. The biggest stock listed in mainland China has lost US$78billion since onshore markets reopened after the Lunar New Year holiday. Wednesday’s 4.6% drop takes the five-day decline to 15%, the biggest for such a period since October 2018. Moutai had rallied 30% this year through its Feb 10 record close.
