These 44 Maryland Corps had their average stock prices increase by a very robust 211% from January 16, 2009 to August 28, 2013. This 211% increase is 2.3 times the 92% increase in the S&P 500 Index over the same time span.
It's pretty clear to me that Maryland has very effective members not just in the US Senate and the US House, but also a very effective State Governor and a very effective State legislature. More States should be so blessed.
