Virtu Said to Delay IPO Amid Furor Spurred by Michael Lewis Book

Virtu Financial Inc., the high-frequency trader that announced plans last month to sell shares, will start marketing the offering weeks later than bankers anticipated, two people with knowledge of the matter said.

Virtu won’t start marketing the initial public offering until after April 20, a process its bankers had expected to begin this week, according to the people, who asked not to be named because the decision is private.
