Trading on China’s new Nasdaq-style stock market began today, with 25 tech companies listed on the Science and Technology Innovation Board, operated by the Shanghai Stock Market. Called the STAR Market, the board is an initiative by the government to encourage more Chinese tech companies to list domestically by addressing concerns about governance.

Traders cautioned that initial trading may be volatile as investors buy and trade stocks, however, and that warning was borne out today with trading by several companies paused after a surge of buying triggered their circuit breakers, or measures put into place that temporarily halt buying and selling to prevent stock crashes.
