I don't understand what everyone is so pissed about. The news came on CNBC before the market opened and I'm sure that you heard about it around the same time that I did. This happens all the time when the FED does not like where the fed funds rate is at that particular moment. I will acknowledge that they did take in securities that they normally would not have taken in order to bring the rate back to normal, and I have one word for that:
SMART
What is happening is that we are in a liquidity crunch and not a normal market downturn. If you listen carefully, you will see that people have trouble VALUING these MBS's and so the funds have to post larger losses because their huge amounts of MBS's don't have values any more (making their value = 0). If I had an unbelieveable amount of cash right now, I would be picking up these things right and left and that is exactly what insti. guys like insurance companies are doing because these are a great long term play. There is nothing wrong with the underlying, it is simply a problem with valuation because no one wants them. If I had $10m sitting around, I would throw it into AAA rated bonds at $50, it's just sound long term investing.
