Hong Kong stocks crammed on more than 2.5% to lead the region's gain in morning trade, and the Hang Seng index broke through the analysts' technical resistance level of 10,200, with a gain of 275.64 points to 10,236.99. Much of the strength came from a 2% gain to HK$89.50 in the shares of HSBC Holdings, which recently produced half-year earnings above forecasts.
