You really ought to be thanking the corporations that are borrowing cheap money to buy back their own stock, but to each his own.
I'd say you need to thank corporations not spending money resulting in higher earnings on smaller revenues. Obviously, since there's no economic growth, the DJIA is not a reflection of economic growth.
Did you know? in the middle of the great depression, the DJIA actually increased by a larger % that it did since the bottom of 2009. Yet they still called that era the great depression, go figure.
although I suppose it's the one thing the fed's pumping sustained, so I guess you have to give the fed some credit for that, ascertaining the markets didn't collapse for the Donald Sterling's of this world.
