科创板今日正式开市 - 2019年07月22日

The 25 new shares on the STAR Market surged during the morning session on Monday, showing investors' high expectations of China’s new Nasdaq-listed board.
By 11am, the 25 shares jumped 140 percent to 450 percent compared with initial public offering prices. Some shares have been temporally halted for trading for 10 minutes to “cool down” after surging 30 percent.
That was in contrast to the mainstream Shanghai trading board, where price gains are capped at 44 percent on debut days and trading swings are limited to 10 percent a day for the duration of trading.
