Shares in small and micro-cap Chinese firms that are listed in the US soared on Friday, echoing rallies of last summer fuelled by individual traders. Online brokerage firm Top Financial Group saw an increase of 645% to $149 per share and Magic Empire Global jumped 328% to reach $3.97. Both are among the most closely watched stocks by retail investors on Stocktwits. Last October Nasdaq halted IPO preparations for four small Chinese firms while investigating other stock rallies.
