The second boost came from United Technologies (NYSE: UTX) (Cramer's Take). Here's a company that really put it on the line, point-blank, saying when pressed that it wasn't just a slowing in the rate of the decline, but an actual cessation of the decline and a stability-linked month. That's huge given that raw costs are coming down and headcount has been reduced. If the dollar doesn't go up (50% of the business is overseas) you can see a nice second half developing, particularly in helicopters and fire safety. If Boeing's (NYSE: BA) (Cramer's Take) actually going to be shipping new airplanes, you are going to see numbers go up, not down, so the move made a ton of sense.

Finally, there is the most significant call of all: U.S. Bancorp (NYSE: USB) (Cramer's Take) (no kidding, did you see the stock?). USB said something I haven't heard during this whole banking crisis, not even from the great minds of JPMorgan Chase (NYSE: JPM) (Cramer's Take). U.S. Bancorp said the problems are getting predictable, and can be gamed and gauged.

This whole time it has been "Wild West" in banking, with no major banker ever seeming to be able to come to grips with how bad things are. That's how USB had been. But not after this quarter. They are modeling again. Plus, they saw the consumer being able to handle the debt load a little better. Maybe USB is on some sort of island, but as the sixth-largest bank in the country, its positives can't be viewed as insignificant.

All three of these were skirmishes won by the bulls that made the day end up nicely higher. There are tons of little battles going on all of the time in the market. These three bull victories won't even merit statues or plaques, but they were notable nonetheless and explain why a market can turn on a dime from looking just plain awful to looking pretty darned good.

Random musings: Packaging Corp. of America (NYSE: PKG) (Cramer's Take) talked about April being stronger than March for corrugated, a great lead indicator, in Tuesday night's call. It's worth a listen.
