The housing crash happened in 2006, though. I suppose being able to predict the crash even a few months in advance is impressive, but as you're hazy about the years, it is possible that it was really 2006 and the crash had already happened, which isn't so impressive.

2008 was the securities crash. That is when the mortgage market started to crumble under the weight of housing no longer having the value it once did with mortgagers left underwater. The housing market had to crash beforehand in order for this to happen. Once one saw that the housing market had crashed, it wouldn't take too much of a Kreskin to realize securities were on the horizon.
