Facebook stock sank today in the first day of trading without the full support of the company's underwriters, leaving some investors down nearly 25% from where they were on Friday afternoon.

Shares fell $4.64 to $33.67 in the first minutes of trading. That represented a decline of more than 12% from Friday's close and about 24.4% from the intra-day high of $45 a share.
