The benchmark Hang Seng Index added 501.05 points to end at 22,013.57 on turnover of HK$65.98 billion ($8.51 billion).
World markets were hit on Monday when China released figures showing the economy grew 7.7 percent in the January-March quarter, slower than expected and weaker than the 7.9 percent in the previous three months.
The news raised questions about the strength of a recent pick-up in the economy, which is a key driver of growth for other nations.
On Thursday the Hong Kong rally was helped by a jump in Shanghai that came thanks to reports in state media that China could approve as early as this month new investment quotas for overseas financial institutions looking to enter the market.
Lenovo rebounded 9.5 percent to HK$7.06 on news it is in talks to buy part of IBM's server unit. The jump follows a recent slump fuelled by concerns about demand for PCs after data showed sales had tumbled.
