The Globe and Mail reports in its Tuesday edition that aspiring equity marketplace CIX Trading wants to bring extended stock trading hours to Canada, but the Toronto Stock Exchange says the upstart plan poses a potential threat to the stability and integrity of the country's capital markets. The Globe's Jameson Berkow writes that in a letter submitted to the Ontario Securities Commission last month, TMX Group, parent company of the TSX and TSX Venture Exchange, warned of "profoundly disruptive consequences" if CIX is cleared to start offering new features such as extended hours and fractional trading later this year. Permitting CIX to begin operating an alternative trading system (ATS), TMX said, would "allow a single market entrant to trigger de facto market structural changes across the entire ecosystem," the letter said. CIX, led by TMX veteran Jeff Foster, wants to execute trades of Canadian stocks from 7 a.m. ET through to 8 p.m. ET, instead of the current trading day that starts at 9:30 a.m. ET and ends at 4 p.m. ET. Mr. Foster said TMX was employing scare tactics in the hopes of buying itself more time to build out new features to compete with CIX. "It is delay, delay, delay and fearmongering," Mr. Foster said.
