Last year when Facebook Inc (NASDAQ:FB) shares plunged after the botched IPO, its founder Mark Zuckerberg aggressively came forward to protect the shares of his social networking site. He promised not to sell his own shares of Facebook Inc (NASDAQ:FB), announced several income-boosting initiatives and squeezed cash from every possible sources of income for the company.

After celebrating its IPO anniversary, Facebook Inc (NASDAQ:FB) stock is tumbling again. Shares have declined about 20.7 percent from May 2 to June 5 this year. But Zuckerberg has shown no urgency this time. The social network is going through a tricky shift from desktop to mobile, that’s what the company is focused upon, says Nathan Vardi of Forbes.

Facebook COO At AllThingsD Conference

Facebook Inc (NASDAQ:FB) chief operating officer Sheryl Sandberg said at the All Things Digital conference that she couldn’t speculate what the view of the Wall Street is since Facebook Inc (NASDAQ:FB) went public more than a year ago. Instead, she talked about the company’s growing user base and engagement. Sandberg said Facebook Inc (NASDAQ:FB)’s user base grew from 845 million to more than 1.1 billion over the past one year. And now more than 60 percent of users return to the social networking site every day, compared to 58 percent a year ago.

Nathan Vardi says it’s ridiculous for a COO to get away by saying something like that when the company has lost over $40 billion in market value since last year. The stock is currently trading 37.83 percent below its IPO price because the company has generated only uncertainty and question marks for the stock market.

Last week, several major advertisers suspended their marketing on the Facebook website because their ads appeared next to offensive posts supporting violence against women.

Analysts Give A Breathing Room

Last week, Jefferies and BMO Capital Markets gave Facebook Inc (NASDAQ:FB) some breathing room by upgrading the stock. Jefferies said the recent decline in share prices is due to declining youth engagement on the site. It created a buying opportunity for investors. But the stock got a boost from analyst upgrades. Many investors used it as an opportunity to sell their holdings at profit, pulling the stock back down.

Facebook Inc (NASDAQ:FB) shares were down 2.27 percent to $22.99 at 1:13 PM EDT.
