Mainland investors continued to buy up Shenzhen B shares, pushing the index to its highest point in 18 months.
It surged 10.6 points to 92.06 as turnover hit $191.7 million - the strongest since the 1992 bull run.
Great Wall Securities (Bin He) general manager Yu Jun said: 'Gains were across the broad as investors snapped up any shares available without considering fundamentals.' Traders said the buying spree was sparked by expected measures to revive B shares, similar to the market-boosting reforms introduced by Shenzhen authorities to A shares in past months.
The Shenzhen A-share index is up 70 per cent since the start of the year. With surging A share prices, domestic investors are more willing to put their money on cheaper, foreign-accessible B shares.
At Thursday's close, they were trading at a 50 per cent discount to their A share counterparts.
While Chinese investors have been scrambling to be part of the market, foreign funds have taken advantage of the rally to sell.
