CSC Financial Co. said Tuesday that its first-half net profit nearly doubled from a year earlier on strong growth of its major financial businesses.

Net profit rose 97% to 4.58 billion yuan ($661.8 million), as operating income jumped 68% to CNY9.9 billion, the Chinese broker and investment bank said.

Operating income from its trading business recorded the fastest growth, more than tripling, while revenue from its investment banking and wealth management businesses grew around 20%, CSC Financial said.
