Hong Kong stocks powered ahead again on Thursday, extending the previous day's surge by ending up 3.67 percent, or 962.37 points to 27199.23 points midday.
At one point in the morning session, the Hang Seng Index advanced 6.4 percent, almost reaching 28,000 points.
Analysts said the momentum was fueled by hopes of fresh money inflows from the Chinese mainland investors seeking arbitrage opportunities.
Shares in Hong Kong soared 3.80 percent on Wednesday as mainland investors capitalized on the Shanghai-Hong Kong Stock Connect program for the first time, while the turnover also hit a record high of 250.03 billion HK dollars (about 32.14 billion U.S. dollars).
