Yesterday they came out and said they wouldn't need an extra $2B that they had previously asked for in bail out money. That's all that has come out positively for GM that I'm aware of.
Invetors are looking for anything that could be taken as good news and running with it. Just like how GE's stock went up when it's credit rating was actually lowered, but since it was less than expected, folks took that as good news. Go figure
There are tons of people on the sidelines, cash in hand, waiting to jump in. If/when the market turns the corner, there will be a damn sunami of cash flowing back into the market's.
Don't get too excited. GM's announcment yesterday that they wouldn't need the federal monies for March probably helped their position a bit. Their recall problems didn't hurt them as much as it could have, because sales as a whole are so depressed, it's not as though tens of thousands of people will suddenly now run out and buy a Ford product instead of a GM product.
The thing is, is that the downturn is partially a mental issue also. If someone thinks they are going to get canned next week they are not going out and spending. If consumer confidence was boosted jujst a little bit we would see significant progress.
