High-frequency trading firm Virtu Financial is taking steps to file a revised initial public offering prospectus after delaying a debut last year, Dow Jones reported, citing people familiar with the matter.
The firm will file revised paperwork with the U.S. Securities and Exchange Commission in "the coming days," Dow Jones reported. It indefinitely delayed its IPO last spring amid scrutiny of the high-speed trading process after the book "Flash Boys" was published, the report said.
