UPDATE 1-China's CITIC Securities reports 37% rise in first-half profit

(Adds detail, context)

SHANGHAI/BEIJING, Aug 19 (Reuters) - CITIC Securities Co posted a 36.7% jump in first-half profit buoyed by busier domestic capital markets, China’s largest brokerage reported on Thursday.

Net profit rose to 12.2 billion yuan ($79.24 billion) for the six months to June 30, it said in a stock exchange filing, largely in line with preliminary results released in July.

Chinese brokerages are benefiting from higher volumes in the stock markets, with a total of 8.1 trillion shares being traded in the Shanghai and Shenzhen exchanges in the first half, according to the bourses, up 4% from a year earlier.

The sector, which has over 130 players, earned 90.3 billion yuan in net profit in the first half, up 8.6% from a year earlier, while revenue rose by 8.9%, Reuters calculations based on data from the Securities Association of China showed.

CITIC’s revenue from stock investments increased 9.5% to 9.8 billion yuan while its brokerage business saw revenue jump 40.7% to 9.2 billion yuan. Revenue from securities underwriting rose 23%, it said.

The company said it would enhance its underwriting business by closely following policies in domestic stock markets such as a further promotion of registration-based initial public offering schemes and homecomings of overseas-listed companies.
