Chinese stock exchanges have introduced daily restrictions on net share sales by hedge funds and large retail investors, four sources with knowledge told Reuters on Friday. Beijing ramps up efforts to stabilise its markets amid an escalating trade war with the United States. The sources revealed that a soft cap on daily net sales had been imposed, with brokerages issuing verbal warnings to investors exceeding the limit. The threshold for individual hedge funds and major retail investors was set at 50 million yuan ($6.83 million), according to two investor sources. The move reflects growing concerns in Beijing over market volatility as tensions with the US continue to mount. Attribution: Amwal Al Ghad English
