Facebook CEO Mark Zuckerberg.
Facebook's stock came very close to hitting its original $38 IPO price today, closing at $37.62.
Facebook's stock hasn't closed above $38 since its first day of trading last year. But in the last week, its stock has been on a tear. Today, the stock got as high as at least $37.95.
Part of Facebook's recent stock jump is due to its better-than-expected earnings report last week.
The numbers in its mobile business were especially good. Facebook said 41% of its ad revenues came from mobile, a huge jump.
