In the following video, Motley Fool senior technology analyst Eric Bleeker tells tech investors why this sector has had such a miserable performance so far in 2013. He breaks down the narratives for some of the best players in tech so far, such as LinkedIn (NYSE:LNKD.DL) and Arm Holdings (NASDAQ:ARMH), as well as the worst-performing tech companies of the year, such as Apple (NASDAQ:AAPL) and Baidu (NASDAQ:BIDU). Finally, Eric tells us what's behind the over-arching trend of investor fears about mobile instability over the coming few years, and why it is driving down the stocks of some otherwise very impressive companies.
