Shares of CITIC Securities, one of China's leading brokerage firms, soared 6.47% on Monday, riding a wave of optimism surrounding the country's economic revival. The stock rallied to close at HK$18.76, outpacing gains in the broader market.

The surge was largely fueled by encouraging data that showed China's services sector expanded at a faster pace in October. The Caixin services purchasing managers' index (PMI) rose to 52.0 last month, up from 50.3 in September, marking the biggest increase in nearly two years and signaling a recovery in domestic demand.

The upbeat PMI reading, coupled with signs of stabilization in the property market, bolstered investor confidence in China's economic prospects. "The improving economic data points to a sustainable recovery in China, which bodes well for the financial sector," said Olivia Chen, an analyst at Guotai Junan Securities.

As a leading brokerage firm, CITIC Securities is well-positioned to benefit from the economic revival, which is expected to drive increased trading activity and capital market transactions. The company's strong market position and diversified business model make it an attractive play on China's economic resurgence.
