Shares of Facebook, which were given a boost last week when the social networking company reported first quarter results that largely met analysts’ expectations, may be over valued, financial newspaper Barron’s said.

Facebook closed at US$ 28.31 on Friday, 60 per cent higher than last summer’s low-point, but well below its initial public offering price of US$ 38 last May. However, the company is probably worth no more than US$ 25 a share, Barron’s said, reiterating a stance it took in February.
