The aforementioned LinkedIn is also a star so far. Based on Wednesday's closing price of $77.45, the stock is up 72% since pricing its $353 million offering at $45 per share. The business-oriented social networking company originally expected to come to market in the $34 range, so the underwriters did boost the price in the face of heavy institutional demand, but it seems they still left a hefty amount of money on the table. After flying as high as $122, the stock has obviously come back to earth a bit but 70%-plus appreciation is hard to complain about in such a short stretch. There was a good amount of speculation that the opening of options trading a week after the stock's debut would take a toll but the shares are holding up fairly well, given the action in the broader market. It's also worth noting that the company has already telegraphed that it's going to lose money in the current fiscal year, so it's possible that some investors could look to book gains if LinkedIn 's first quarter as a public company is awash in red ink.
