Roundtable: 1 Stock to Buy in March – Coach, Inc. (COH), United Technologies Corporation (UTX), Kinder Morgan Energy Partners LP (KMP)

Tim Beyers: Every portfolio needs a battleground stock — a company so loved, and so equally reviled, that imperfect pricing of the underlying business is bound to occur. You know the sorts of stocks I’m talking about: Apple Inc. (NASDAQ:AAPL), Sirius XM Radio Inc (NASDAQ:SIRI), and my pick for this month’s must-own, Tesla Motors Inc (NASDAQ:TSLA) .

I’m in Austin, Texas for the annual South By Southwest Conference, in part, to hear CEO and co-founder Elon Musk talk up the merits of his electric car manufacturer in the wake of a mixed Q4 earnings report and a high-profile fight with The New York Times. Expect bearish investors to growl at whatever bold claims he makes from the floor.

You know what? It doesn’t matter. The truth is, we don’t know exactly how the Tesla story will end. What we do know is that Musk personally controls nearly 24% of Tesla’s shares outstanding, which means he has a lot to lose if the company fails. We also know that production is ramping up to 500 cars per week from 400 just a few months ago, while the stock trades for a little more than twice expected 2013 revenue, which is on track to quadruple.

All that’s keeping Tesla down is skepticism that an electric can take hold on a mass scale. Ford’s five-fold increase in January hybrid sales — a natural bridge between all-gas and all-electric — suggests that these skeptics are well on their way to being proven wrong.

Dan Caplinger:  March is setting up to be an interesting month for Silver Wheaton Corp. (USA) (NYSE:SLW). As a silver-streaming company, Silver Wheaton doesn’t mine precious metals but, rather, offers financing to mining companies in exchange for part of their production. Although the company has focused mostly on silver streams, late last month, Silver Wheaton completed a large gold-streaming deal with Brazil’s Vale SA (ADR) (NYSE:VALE) to provide $1.9 billion in cash to Vale in exchange for streams from Vale’s Salobo mine in Brazil, as well as its Canadian Sudbury mines. As part of the terms of that deal, though, Silver Wheaton also issued warrants that allow Vale to buy 10 million Silver Wheaton shares at any time over the next 10 years for a price of $65 per share. With the stock currently trading at less than half that price, the deal indicates confidence both within Silver Wheaton and at Vale that the silver-streamer has plenty of upside potential. Watch for more news about the Vale agreement and other potential deals in the pipeline when Silver Wheaton reports its quarterly earnings on March 22.

Brian Orelli: Navidea Biopharmaceuticals Inc (NYSEAMEX:NAVB) looks like a good pickup in March, ahead of the Food and Drug Administration decision on the biotech’s lymph node detection agent Lymphoseek. The FDA is expected to make a decision by April 30, 2013.

This isn’t the first time Navidea has been in front of the firing squad. Last year, the FDA rejected Lymphoseek, but the issues seem to be limited to third-party manufacturing facilities rather than with the drug itself. Assuming Navidea’s concluded correctly that its contractors have taken care of business, the diagnostic looks like it has an excellent shot at getting approved.

Despite the high likelihood of success, Navidea trades substantially below where it did before the last FDA decision. You’re getting a more-likely approval for cheaper. Sounds like a good deal to me.

Investors should be careful though. If it runs up too much, I wouldn’t be surprised to see the typical sell-the-launch mentality that’s become rampant for small biotechs launching their first drug. Navidea could turn from a good buy in March to a good sell in April if its valuation gets out of hand.

Justin Loiseau: The world of utilities is changing fast, and NextEra Energy, Inc. (NYSE:NEE) is ahead of the rest. As the largest producer of renewable energy in the United States, NextEra’s energy portfolio has more diversity than any other major player.

The company has had made significant inroads with cheap natural gas, and its 10,000 MW of wind investments just received another 10-year round of production tax credits to keep costs competitive.

Even as NextEra leads in innovation, its bottom line hasn’t felt the squeeze. The company just beat analyst earnings estimates for Q4 2012, and its 22.9% operating margin is better than over 80% of its competitors.

Sales are slowing down for utilities, and picking progressive companies will pay off more than grabbing the biggest dividend. NextEra’s below-average 3.7% yield won’t win any favors with income investors, but its low payout ratio and steady cash flow should guarantee its sustainability, which is more than one can say for Atlantic Power Corp (NYSE:AT)‘s recently slashed 10% yield.

NextEra shares are up 24% in the past year, but the company’s pricing is still reasonable if you consider the increasing importance of bottom linenumbers. Give yourself a break from March Madness and electrify your earnings with NextEra today.

Matt DiLallo: As Americans, we want energy independence that doesn’t cost us our beautiful environmental surroundings. We’ve discovered enough natural gas and oil trapped beneath our soil to give us hope that energy independence might one day be a reality. Unfortunately, it takes a whole lot of water to get it, which doesn’t sit well with our environmental leanings.

That water, which is pumped down a well along with sand and chemicals, is a critical part of the fracking process we’re using to unlock our vast energy potential. Let’s just say that when the water returns to the surface, it’s not fit for human consumption. Enter Heckmann Corporation (NYSE:HEK), an environmental services company that’s in the business of transporting, treating, and then recycling or properly disposing of all that frack water. While the company is growing rapidly by rolling up its competition, the market has all but disposed of its potential.

At issue, the market sees Heckman as a play on the growth of natural gas. What it’s missing is that 70% of Heckmann’s revenue is actually derived from liquids and oil-focused plays. It’s also punishing Heckmann’s growth-by-acquisition model, which has muddied its financials. However, when you clean out some of the mess, you’ll see a company that’s producing underlying earnings potential that will be realized as we keep on fracking. Right now, the market’s judgment is clouded by these misconceptions, which allows investors buying today the opportunity to really clean up as Heckmann’s market position and financial picture begin to clear up.
