“It’s not as if they have to sell all their holdings the moment the market opens,” said Brian Wieser, an analyst at Pivotal Research Group, who rates the stock a buy. “They want to be rational about this.”

With the end of the lock up period, stock prices are expected to plunge further. Over the next nine months, about 1.91 billion shares will hit the market, compared with fewer than 500 million now available for trading.

Many potential investors are confused whether or not to go for Facebook Inc (NASDAQ:FB) shares, as they are unsure about its prospects. “It’s one of the No. 1 issues on investors’ minds right now,” said Herman Leung, an analyst at Susquehanna International Group, said. “Even the investors that I talk to who want to buy the stock and like the company, are not sure if they can stomach the lockups.”
