Hong Kong (CNN Business)The Chinese government is trying to dampen demand for local tech stocks after President Xi Jinping personally endorsed blockchain technology, sending their value soaring.
Stocks of almost 200 companies that invest in blockchain technology jumped around 8% on Monday, according to an index compiled by East Money Information, with some very quickly hitting their daily limit of a 10% increase. The spike came three days after Xi called for faster development of the blockchain sector, according to Chinese state-run news agency Xinhua.”(Xi) stressed the importance of stepping up research on the standardization of blockchain to increase China’s influence and rule-making power in the global arena,” Xinhua said.According to two inquiries sent by the Shanghai Stock Exchange and seen by CNN Business, companies involved in blockchain services were asked to better explain their businesses and keep their official statements factual and simple to avoid hype.Read MoreThe Chinese government is also trying to manage investor enthusiasm.A commentary published by the Communist Party’s official mouthpiece, the People’s Daily, called for Chinese market traders to restrain themselves.”Of course the future of blockchain is here but we must stay rational,” the commentary published Monday said. “Blockchain innovation does not mean speculating virtual currencies … We must also see that the blockchain is still in the early stages of development.”The stocks in East Money Information’s blockchain index have been paring back their gains since Monday.
