The Securities and Exchange Commission dealt a fresh blow to stock exchanges’ lucrative business of selling data and high-speed connections, the Wall Street Journal reported. New guidelines from the regulator, released yesterday, will make it tougher for exchanges to boost fees for such services by requiring them to include detailed disclosures each time they seek to adjust a fee. The SEC last year rejected two data-fee increases imposed by the New York Stock Exchange and Nasdaq Inc., prompting them to challenge the regulator’s decision in a federal appeals court.
