Before the bell: Stocks rise in Europe & Asia, dollar stronger, Microsoft-Yahoo saga continues

Some investors are starting to believe that the worst of the credit crunch is behind us, and European banks including UBS (NYSE: UBS) and Royal Bank of Scotland (NYSE: RBS) are leading a bullish move in the markets.

The dollar stabilized and oil weakened, giving a boost to many blue chip stocks. Home Depot (NYSE: HD) rose nearly 4% in trading on Thursday, and American Express (NYSE: AXP) was up nearly 7%.

Not all news is positive, however. U.S. futures are flat as the markets await the Labor Department's official employment report, due today. According to Bloomberg's calculation, unemployment in the U.S. continues to rise as employers shed more than 75,000 jobs in April. The unemployment rate is now probably at 5.2%, a three-year high. And real unemployment is probably worse that that, since the Labor Department's calculation method, which Bloomberg uses, significantly undercounts unemployment and underemployment.

And the Microsoft-Yahoo! saga continues. The AP reports that Microsoft (NASDAQ: MSFT) may go hostile in its bid to buy Yahoo! (NASDAQ: YHOO) today. Should be entertaining, so say tuned.

UPDATE: Job numbers better than expected, unemployment falls to 5.0%.
