LinkedIn sold off hard today (-9.3%) as management guided slightly lower than analyst's were expecting for the final three months of the year. LinkedIn has been on a tear this year. Before the sell off today, LNKD was up 136% and had outperformed the MSCI World Index by 90% over the past year. It had been the 17th best performing stock out of nearly 1600 in the MSCI World over the past year. The stock looks to be in an uptrend but has it gone too far, too fast? A correction, either through time or price, would seem likely as current overhead resistance has proven too be stubborn.
