Mr. Market didn't appreciate Dell's (Nasdaq: DELL) fourth quarter at all. You should take advantage of that mistake.

Shares fell more than 6% in early trading when the computer builder missed analysts' earnings targets. Total revenue of $16 billion nudged past Street estimates, but $0.51 in non-GAAP earnings per share fell just a sliver short.

Gross margins were held back by a surprisingly low-end product mix in spite of Dell's stated desire to go upscale. But the quarter wasn't entirely devoid of good news. Total sales rose just 2% year over year, but large enterprise revenue jumped 5% and business was brisk in the BRIC bloc with a 10% sales leap. And while consumer sales in the U.S. sank, the rest of the world actually wants to buy Dell's consumer systems now. In particular, the top-shelf line of XPS notebooks more than doubled its sales in fiscal 2012.

So the overall strategy seems to be working as Dell moves further into high-margin sales. Looking ahead, Dell expects earnings to rise in 2013 while analysts predict modest shrinkage. That's the kind of rosy outlook that tends to trump a slight earnings miss, but not this time.

Keep in mind that last night's drop only erased a couple of weeks' worth of Dell's steady share-price gains in 2012. The company looks fundamentally healthy and headed in the right direction; drops like these give us sideliners a terrific opportunity to get into Dell. However, if Dell doesn't seem like your flavor, Foolish analysts have found an even more promising stock for your portfolio.
