If you watched the tech markets in 2007, you saw turmoil in some companies and triumph in others. Of course, I'm talking about stock prices first and foremost. The market can be unforgiving. Earnings in line with expectations can cause a stock to shrink while beating expectations by even a penny per share can cause a stock to rise. It's all about context in the industry.

So, how about some winners in 2007. Let's list them here courtesy of Om Malik: Research In Motion (NASDAQ: RIMM), up 166.3%; Amazon.com (NASDAQ: AMZN), up 134.8%; Apple Inc. (NASDAQ: AAPL), up 134.7%, Google Inc. (NASDAQ: GOOG), up 50.2%, Microsoft Corp. (NASDAQ: MSFT), up 20.9%, eBay (NASDAQ: EBAY), up 10.4% and Yahoo! Inc. (NASDAQ: YHOO), down 8.9%. Wait -- why is Yahoo! in there? So a comparison to 2008 performance can be made a year from now.

Why did the stock prices of all these companies shoot up so high in 2007? Research In Motion continued taking the crown in mobile e-mail, Apple released the iPhone, Google continued phenomenal growth every quarter . . . you get the picture. Yahoo! was the lone loser out of the above group based on it continuing to lose ground to Google, the weak response to its new search engine platform and the ousting of former CEO Terry Semel after a few years of disappointing results. The other companies saw share gains for one reason or another. Will all of them see more gains at the end of 2008? You make that call now -- and add to your portfolio if you have the itch.
