Peck's second pick was Facebook, which fell nearly 4 percent.
Peck, who has a "buy" rating and a $70 price target on the stock, said that Facebook is setting up to have a strong quarter.
"You're seeing growth north of 70 percent, incremental margins around 80 percent; the core continues to chug away," he said.
Lastly, Peck said that he'd be a buyer of Google, which sold off around 2 percent.
"I always look for franchises on pullbacks," he said, adding that Google remains "one of the best business models out there on the Internet."

Peck also addressed a report out Tuesday claiming that YouTube's revenues were far below analyst estimates.
"It came from a blog source … they don't break the information out, so we may never truly know," he said.
