The rise of off-exchange trading in the U.S. stock market continues unabated even as regulators question the wisdom of allowing the shift to continue.
Shares changing hands in private venues such as dark pools accounted for 40.4 percent of total share volume on June 10, according to data compiled by Bloomberg. That’s the most since 41.7 percent took place off-exchange on June 22, 2012. The three biggest exchange companies each matched about 20 percent of trading on June 10.
