The stock jumped $1.41, or 5 per cent, to close Thursday at US$29.60.
That comes after three consecutive days of declines. The stock is still down 22 per cent since its highly anticipated initial public offering two weeks ago.
Facebook Inc. began trading on the Nasdaq Stock Market on May 18. The day started with a delay due to trading market glitches and didn't get much better from there.
The company, along with the investment banks that led the IPO, is also the subject of at least two shareholder lawsuits.
They allege that analysts at the large underwriting investment banks cut their financial forecasts for Facebook just before the IPO and told only a handful of clients.
Morgan Stanley has declined to comment. Facebook calls the lawsuits "without merit."
Standard & Poor's equity analyst Scott Kessler, who has a "Sell" rating on Facebook's stock, lowered his target price to $27 from $30 on Thursday. He also lowered his earnings forecast to 39 cents from 40 cents for 2012.
