EMC kicked off 2011 with a major product launch and introduced its new VNX/VNXe family of SMB storage appliances. Its stock even rose nearly $4 per share early in the year, but that was all erased by the end of the summer. Shares rebounded in October to nearly $25 per share but settled back down to close the year down 6 percent.
