It seems all the econ data is priced in, as we saw in the prior two weeks. Bad sales numbers, housing data are expected. What matters more importantly is the outlook.
These huge funds run by smart people realize that the feds' bailouts, stimulus packages, and rate cuts will create an environment for sustained, multi-year growth and are loading up before the future econ data cofirms this. Also, the extent of the so called "recession" is very shallow. Even 8% unemployment (if it should get that high) and even a 2% contraction in GDP isn't a big deal by historical standards.
Finally, bear markets and recessions tend to be very brief and usually last no longer than 1-2 years. The recession tends to last just eight months. The reason why this so is because of fed intervention, free trade, and consumer spending.
I could go on, but I feel more confident about being long now (even with a large loss) than ever before.
