Facebook picks "FB" symbol for a May stock market debut The countdown continues on the Facebook road to the public stock market. Word has come out that Facebook will be traded on Nasdaq under the ticker symbol "FB," according to The New York Times. So it looks like Nasdaq won a battle with the New York Stock Exchange for one of the highly largest tech IPOs ever -- Facebook. Nasdaq hosts Apple, Microsoft, Amazon and Google, while the NYSE have smaller public tech companies like LinkedIn, Yelp and Pandora Media. The social networking company that has been marching ever forward toward the public market is preparing a $5 billion IPO for sometime in May. Word is also circulating that Facebook has halted the trade of its shares in secondary markets SharesPost and SecondMarket over the last few days.
