Virtu soars nearly 20% on IPO

Virtu: Market efficiency never been more profound

On a day that had already seen two companies skyrocket on their respective IPOs, Virtu Financial was no different.

The high-frequency trading firm saw its shares soar nearly 20 percent Thursday after the IPO to more than $22 a share. Virtu had priced its IPO at $19 a share. Click here to see where the stock is trading now.

Executive Chairman Vincent Viola said his New York-based company owes much of its success to making the right decisions at the right time.

"It comes down to the law of large numbers. If you do anything and you win more than you lose … you're going to be profitable. We trade over 500 million times a day and we win more than we lose," Viola said in an interview on CNBC's "Squawk on the Street."

The IPO came after Party City and Etsy also opened for trading. Party City's stock surged more than 20 percent after pricing its shares at $17 a share. Nevertheless, both Virtu's and Party City's IPOs pale in comparison to Etsy's.
