Look at the flow and look at what were up, it is not the rocket science to figure out most of them r short covering.
2. Why the news made the market up?
Technically spking it was the short covering but practically spking u shd really think that it gave a HUGE relief to the mark to market risk for those banks' mortgage portfolio.
3. Why not 2 months later?
MS pointed that out for ya, ask them or read some more abt the accounting fraud that they 2 were applying. Paulson is not stupid, he is a patient guy but he just could not afford to sit there and waited til then.
4. Shd this happen?
Of course not, but u have no choice. Too big to fail, for the time being.
The question u shd ask is who the fcuk let those sh1ts grow so big? Ask that Frank of 1930's.
