Roku (ROKU) shares surged 21% Thursday following upbeat financial results for its second quarter, which included the addition of 22 million new accounts. 

Revenue grew 45% year-over-year, which is in line with some of the pricier technology stocks, such as Facebook (FB) . Roku stock trades at $57.32 a share.

Real Money contributor Stephen Guilfoyle, likes the name and tried to buy the stock before Thursday's earnings release. "I missed it," he said. 

With Facebook, Guilfoyle said he wouldn't buy the stock at its current level of roughly $185 a share.
