The Menlo Park, Calif.-based firm made an eagerly anticipated and eventful public debut on Friday in the biggest-ever tech IPO. After pricing its offering at $38 a share, Facebook opened at $42.05 and briefly jumped to a high of $45 before closing at $38.23.
Even though the widely anticipated first-day pop failed to materialize, Facebook's IPO still saw the Nasdaq Exchange struggle with unusually heavy volume. The exchange resorted to manually delivering executions to brokerage houses.
On Sunday, Robert Greifeld, the CEO of Nasdaq OMX Group Inc. (NDAQ - Get Report), acknowledged technology problems related to Facebook's listing, according to a published media report, saying the exchange was "humbly embarrassed" by Friday's events.Shares of Facebook dipped 3.3% to $36.96 in pre-market trading today.
