[day one action]
[underwriters protect the break-even level of 38 on the day one, but second day, a monday, saw stock plummet 10%. Nasdaq, the exchange on which FB got listed, had its own problem with starting the IPO on the scheduled time of start. Underwriters soon put the blame on Nasdaq for their ipo disaster.]
[ps: mark zuckerberg married his GF in the weekend after day one, a friday. ]
