The firm pleased investors earlier in the week, when it offered better than expected first quarter revenue guidance. Management said it anticipated Q1 sales of $216 million, topping the average analyst view of $203.46 million. The solid performance was attributed to better marketing and customer retention. Separately, Chairman and CEO Michael Hagan said he would relinquish his chief executive title to President and COO Joseph Redling on May 1st. The stock was subsequently upgraded to "market perform" by Boenning & Scattergood, which also declared a $30 price target.

Shares in weight-management company NutriSystem Inc. (NASDAQ: NTRI), which have starved investors over the last year, falling from over $70 to as low as $12.55 a share, are surging more than 30% today on news of a new CEO and the release of preliminary numbers much stronger than analysts had expected.

Earnings estimates for the first quarter show revenues of $216 million, $13 million more than analysts had figured. The company also named Joseph Redling as the new CEO.

According to a report in Forbes, current Chairman and CEO Michael Hagan said: "The business is in good shape as we enter the second quarter. The business performance in the first quarter was better than expected as the marketing efficiency in the latter stages of the quarter showed improvement, and it's certainly stabilized versus January trends. We also continue to witness improvement in our customer retention efforts and in the business of reactivating ex-customers."

With all the eating that took place over the last few weeks, it's time to try and shed those unwanted pounds. For those looking to invest based on this inevitable trend, take a look at NutriSystem (NASDAQ: NTRI). The company offers a weight-loss program based on portion-controlled, lower Glycemic Index prepared meals. The stock has certainly shed some girth over the last year, getting trimmed by over 65%.

While you can let me know if you think their meals are tasty or not, at these levels the stocks looks really attractive, sort of like the piece of hot chocolate cake that is staring me in the eyes as I write this! The stock is trading at a PE of just 8.08 and a PEG of 0.44. Their remains a large short-interest on the stock, which is keeping the pressure on, but if the company has some good news, the shorts will have to cover and this could take off like a rocket. At $25 a share, this looks like their will be plenty of upside to the stock price.

Three years ago yesterday, Google (NASDAQ: GOOG) became public. Since then, those investors who could get past the seemingly high valuation of $85 per share have been generously rewarded with a hefty return of 478%. Google has been a perfect example of the need to look forward when analyzing growth companies. At the time of its IPO, value investors (rightfully so) appeared on CNBC to tell investors that Google was overvalued. However, because Google was able to grow its earnings per share at such an unbelievable rate, the stock's IPO price represents just 8x last year's earnings and 5.5x this year's. Given the choice to buy Google at $85 per share now I'd bet every value, growth, stupid and smart investor would jump on the opportunity to pick up the stock.

But Google hasn't been the only incredible performer during the last three years. In fact, Business Week has an interesting article listing the companies and stocks that outperformed Google during the last three years. You'll find that many of these stocks rose due to some huge underlying trend that these companies were able to ride out for powerful growth.

For example, high oil prices have been a huge trend for profits. Frontier Oil (NYSE: FTO) was able to return 611% to investors over the last three years as the company rode the increased oil prices to make huge refining profits. Foster Wheeler (NYSE: FWLT), with its focus on energy, pharmaceuticaul and environmental infrastructure products, was able to return 557%.

After the bell Tuesday, popular momentum name NutriSystem (NASDAQ: NTRI) reported earnings. While the earnings report was extraordinary -- 70% year over year growth, handily beating analyst estimates, and so on. The company's third quarter guidance cut was enough to send the shares down about 15% in after-hours trading.

While this sounds crazy, I think the company could very well be lowballing its guidance for a variety of reasons. First and foremost, I don't think NutriSystem executives expected the stock to react so poorly to the guidance cut considering the first quarter figures solidly beat the street. In other words, I think the executives expected the incredible second quarter to easily trump any news of a weaker third quarter.

I'm well-aware of the fact that the new weight-loss drug Alli could stand to hurt the company, but I think the primary reason for this guidance cut was to improve Wall Street's perception of the stock when they report next quarter. Faced with tough year over year comparisons from the Dan Marino campaign in Q3 of last year, the company wanted to have something to boast about -- crushing guidance.

While some will argue that the company is betting on higher TV advertising costs, I don't think the true squeeze from advertising costs will come until early 2008 when election campaign spending heats up dramatically and TV stations can increase rates due to the high demand.

I may very well be crazy, but I think NutriSystem is playing the guidance game. Even though the stock looks cheap here, I'd be careful.

Contradicting those who say there is no fat left in the American market, NutriSystem (NASDAQ: NTRI) has made our waistlines its bottom line, and it too is growing nicely. Having outlasted the Atkins craze, the company yesterday reported a hefty 62% increase in earning for the first quarter of 2007 of $238.6 million. Better yet, net income grew 70%, bringing EPS to $1.04, well above the $.91 expected by analysts polled by First Call/Thompson Financial. This compares to a skinny $.60 in 2006.

Ironically, the company is thriving, according to CEO Michael E. Hagen, in part from its failure to provide a long term solution for its customers. In his words, "an integral part of our first quarter has been the ongoing expansion of our pool of ex-customers and their desire to return to NutriSystem for weight management services. The operating margin expansion we saw in the first quarter was partially due to the growth in revenue from ex-customers." Direct sales were also a hefty contributor, up 52% over 2006 to 358,000. Confident in the American appetite for cheesy fries, the company raised guidance for 2007 to $3.34-$3.46.

The company's emphasis on direct sales, lack of direct competitors and its valuable, ever-growing database of people who share my tendency to expand and contract, cause long-term prospects for NutriSystem to look plump. After all, if you pair a milkshake ad, candy bar ad, or a beer ad with a swimsuit ad, what do you get? A NutriSystem ad.

Tonight on his CNBC show, "Mad Money," investment strategist Jim Cramer talked about why he likes companies that make money outside the U.S.

Wall Street used to focus primarily on what are known as "BRIC" countries -- Brazil, Russia, India and China. Now investors should "ROW" he says. That's short for, "The Rest of the World."Stocks without international business should get a black mark, while cyclical American companies that do business overseas deserve a huge premium, he believes.

There are three ROW stocks that Cramer recommended tonight:

1. Caterpillar Inc. (NYSE:CAT): Not only does it get half of its revenues from outside of the U.S., but it also has also has half of its plants outside the States.
2. E.I. DuPont de Nemours (NYSE:DD): It gets 65% of its revenues from outside the U.S. Plus, DuPont has a huge agricultural division. The unit is doing well, Cramer says. He also likes that DuPont is a part of the growth of the corn business.
3. United Technologies Corporation (NYSE:UTX): This was Cramer's last of stocks he recommended that make money in The Rest of the World. It has 60% of its revenue from outside the U.S., he says.

Cramer also mentioned on the show that he likes QUALCOMM, Inc. (NASDAQ:QCOM). He believes it is going to the mid $40s. And he said he wants to ring the register at NutriSystem Inc. (NASDAQ:NTRI), which reported fourth quarter earnings that tripled today.

• Soleil Securities started USA Mobility (NASDAQ: USMO) with a Sell rating and $11 target, as they believe USA Mobility is overvalued in a deteriorating industry.

OTHER INITIATIONS:

• USB initiated Level 3 Communications (NASDAQ: LVLT) with a Neutral rating and $7 target.

• First Albany started Quest Software (NASDAQ: QSFT) with a Neutral rating and $17 target, expecting volatile shares in the near-term due to the options investigation, but expects a resolution in 2007.

• BBN&T initiated NutriSystem Inc (NASDAQ: NTRI) with a Buy rating and $84 target. The firm believes NutriSystem is well positioned to sustain healthy earnings growth given consumer weight problems, along with the effectiveness and low consumer awareness of their program.

Although it's still a while before New Year's Day, diets and healthier eating will almost certainly be near the top of many lists of resolutions. One beneficiary is NutriSystem (NASDAQ: NTRI) – a buy recommendation from small cap expert Tom Bishop.

The editor of BI Research says, "NutriSystem is knocking it out of the ballpark, beating estimates and raising guidance." The company markets and sells the food for its proprietary weight loss system, which is based on a low glycemic index.

Bishop notes the company increased revenues by 141% and earned $0.63 in its third quarter, up from $0.19 last year, which was a "big upside surprise" over Wall Street's estimates.

Helping the company has been its ad campaign, in which former Dolphin quarterback Dan Marino has been pitching the weight loss program. Notes Bishop, "Already 30% of its customers are men, who like the anonymity and do-it-at-home nature of the product." Next up will be promotions aimed at seniors, featuring coach Don Shula - another former Dolphin - and his wife.

Meanwhile, those who wish to oversee their own healthier diets may prefer Whole Foods Market (NASDAQ: WFMI), which recently shed some pounds itself. The stock took a major hit when its lowered its growth forecast for 2007 from 20% to 17%.

Todd Schoenberger, editor of Red Zone Profits, says, "This knee-jerk reaction by traders and investors has presented a wonderful buying opportunity."
