Aug 3 (Reuters) - TMX Group Ltd X.TO , Canada's biggest stock exchange operator, reported on Wednesday that its second-quarter profit more than doubled, helped by lower operating expenses and higher revenue.
The Toronto-based company said net profit attributable to shareholders rose to C$58.3 million, or C$1.07 a share, from C$27.6 million, or 51 Canadian cents a share, a year earlier.
Revenue rose about 9 percent to C$194.6 million, the company reported late on Wednesday.
