The collapse of so many major financial institutions in the past year, and over the past few days especially, is hard to fathom in its enormity. Sometimes you need a good visual to put things in perspective. The New York Times has an interactive graphic up on its site that pretty much says it all. It shows that $4 trillion has been wiped off the total market capitalization of the U.S. stock market since last October. Of that, nearly $1 trillion is from the decline in the financial sector alone.
