I'd like to know what all those sellers are thinking. Really! I mean, look at this chart. There we have it, down down and more down. MSFT is now at its 52-week low -- in fact, the stock hasn't been this low since October 4, 2002. I know! Today, the stock closed at $23.17, down 3.5%. It's now trading 15% below its high last week. Ouch. Guess everyone does believe Gartner's report about Vista delays.

Those who are selling right now? In my opinion, it's irrational depression. Why sell at the low? Panic, I suppose, but it seems highly, um, foolish. Tim Beyers, he who is Motley Foolish but not, you know, foolish, agrees. He argues that, even if you buy the idea that Microsoft might be taking second fiddle to Google (the Evil-Empire-come-lately), it's still a good company to own. After all, they are rife with cash-ola and they absolutely, totally dominate the average laptop. Come on now, look around you at the coffee shop. How many laptops don't have Windows-based software?

Unless you're tapping away at my favorite worker-owned coffee collective (where everyone either has an iBook or a built-from-scratch Linux geek-machine), the answer is: few. If I owned Mr. Softee right now, I'd be holding. And if I owned a pile full of cash right now, I'd be buying. There may be more down. But I'd bet at least some of my children's future on the long-term up.

As of 1:42 this afternoon, MSFT is down 11% - that's a whopping $31 billion in market capitalization in one day - to $24.24. One of the commenters to my post last night suggests that "we all just get out of all stocks and then "all stupid analysts can be fired and work in the fields with the Mexican farm workers, because that's what they deserve !!"

While that makes me laugh uproariously with my buddies at the coffee shop, I really don't blame the analysts here. It's not like Microsoft has really given them precise figures to consider. And, in my opinion (and I'd argue, the opinion of those analysts, themselves), MSFT management strategies are murky at best. The Goldman Sachs analyst in last night's earnings call said it best, "It sounds like you're building a Google or Yahoo! inside the company." They're spending a few billion dollars more than expected (and, more than last year) on "cost of sales" and they're telling us that all that money is being spent on increased Xbox 360 costs. I don't think so. And neither does Wall Street.

Chris Liddell isn't going to tell us what's really going on, and my guess is that Softie is building, deliberately and at great developer expense, proprietary software to do what all their competitors are doing. They've already spent a ton on their own ad serving platform - is that only the tip of the iceberg? The answer, I think, is yes. What do you think should be done about the 11% drop in market cap? And are you considering this a buying opportunity? Or are you run, running as fast as you can?
