When it comes to picking trends, JPMorgan Chase (JPM) has nailed the latest market to experience explosive growth. It is the fast-growing tablet market, as reported in Reuters.

Morgan's analyst, Mark Moskowitz, has upped his forecasts for tablet sales in 2011 and 2012. For 2011 he raised his numbers from $24.9 to $26.1 billion. For 2012 his numbers are increased from $34.1 billion to $35.2 billion. Unit sales were upped by over 1 million to 48.1 in 2011 and 79.6 in 2012.

"Before the iPhone, Motorola's RAZR was the world's must-have handset. But the company failed to come up with a successor and has been bleeding market share ever since," notes Nathan Slaughter.

The editor of Street Authority Market Advisor explains, "Now, Motorola Mobility (MMI) is back. After being lost in the woods for a few years, this former leader has found its way.

"By last summer, Motorola clung to just a 3% sliver of the global mobile phone market and had slipped into 8th place. But the tide began to turn shortly thereafter -- and I am expecting a big comeback in 2011.

Motorola Mobility Holdings (MMI), devoted to cell phones and set-top television boxes, has an overall option implied volatility of 41 according to Track Data.

Investors always look for good things to happen in stocks they own. Things like better than expected earnings, new contracts or a breakthrough discovery that will convert to better sales and profits. But they should also look for red flags, troubling developments within a company that could spell lower earnings in the future, even if they start with the opposite intent.

I'm reminded of that as I read about Microsoft (MSFT) getting into the mobile phone business. Of course, management thinks it will create more sales and profits, else why would they enter one of the most competitive markets on the planet? The problem (the red flag) is that there are already too many mobile phones with every type of application available and profit margins are much slimmer than in software. What can Microsoft add to this market that doesn't exist?

The dealmaking for mobile location-based services (LBS) companies heated up this week. First, high-end audio maker, Harman (HAR), agreed to buy Aha Mobile. The company essentially turns your smartphone into an in-vehicle infotainment system.

And today, we got another deal: Motorola (MOT) purchased Aloqa, which develops software to stream event and digital coupons to smartphones.

"In a number of respects, Motorola (MOT) is the quintessential 'special situations' stock; indeed, I like the various investment angles -- company break up, asset sales, buying by a big insider, a re-energized product line," asserts Chuck Carlson.

The editor of The DRIP Investor explains, "The firm is in the midst of a major restructuring, which includes selling off assets and splitting the company into two separately traded entities.

"The breakup, scheduled for next year, will separate the company's handset phone business from its enterprise mobility business.
