Zuckerberg Disappointed by Facebook Stock Performance, "Doubling Down"

Facebook CEO Mark Zuckerberg hasn't enjoyed seeing his company's stock get pummeled on Wall Street this summer, but he is relishing the opportunity to prove his critics wrong.

"I would rather be in a cycle where people underestimate us because I'd rather be underestimated," Zuckerberg said Tuesday. "I think it gives us the latitude to go out and make some big bets."
