Decrease in Market Value: $15.7 billion >>4 Big Tech Stocks on Traders' Radars Big Blue isn't making any friends on Wall Street right now -- and that shouldn't come as a huge surprise considering the 3.6% drop that shares have posted since that start of 2013. IBM ( IBM) is underperforming the S&P 500 by a hefty 20% right now. For portfolio managers fixated on beating their benchmarks, that performance is unforgivable. IBM builds mainframes, designs software and provides IT services to corporate clients across the world. It's struggled to gain traction along with many blue-chip tech names this year. The firm's hefty shareholder yield should at least come as some consolation for investors who are still holding on.
