Let's see what the numbers say about IPG Photonics (IPGP).

Jul 15, 2014 at 7:25PM

Investors love stocks that consistently beat the Street without getting ahead of their fundamentals and risking a meltdown. The best stocks offer sustainable market-beating gains, with robust and improving financial metrics that support strong price growth. Does IPG Photonics (NASDAQ:IPGP) fit the bill? Let's take a look at what its recent results tell us about its potential for future gains.

What we're looking for
The graphs you're about to see tell IPG Photonics' story, and we'll be grading the quality of that story in several ways:

  • Growth: are profits, margins, and free cash flow all increasing?
  • Valuation: is share price growing in line with earnings per share?
  • Opportunities: is return on equity increasing while debt to equity declines?
  • Dividends: are dividends consistently growing in a sustainable way?

What the numbers tell you
Now, let's take a look at IPG Photonics' key statistics:

How we got here and where we're going
IPG Photonics nearly achieved a perfect score when we looked at it last year, and it's finished with the same six-out-of-seven score this year -- but over the past year, free cash flow growth has finally surpassed the growth of IPG's net income, while its abnormally high return on equity bounce has fallen back to earth. However, the biggest change from last year to this year seems to be a virtual flatlining in IPG's share-price performance. Last year, IPG was nearly a three-bagger in three years, but from 2011 through today its stock has barely budged. What gives? And more importantly, can IPG overcome this weakening of perceptions to again become a favorite of growth-stock investors? Let's dig a little deeper to figure out what's ahead.

IPG hasn't had a very good 2014, as shares have yet to reclaim the price they closed at on the first trading day of the year. Its two quarterly reports filed this year have both produced underwhelming market reactions -- the company's fourth quarter showed shrinking profit margins and weaker-than-expected earnings, and its first quarter report sparked a sell-off as investors began to worry that the company's history of strong growth might be coming to an end. IPG's second-quarter guidance (the company is set to report that quarter's results at the end of this month) projected single-digit growth rates for its top and bottom lines, and while that wouldn't represent the company's weakest growth rates, it certainly continues what's become an ongoing trend of ever-lower year-over-year growth rates over the past two years:

The company's weakening progress has caused even longtime IPG shareholder (and Fool writer) Brian Stoffel to reconsider his position, pointing out that IPG has faced heightened levels of competition in the fiber-optic laser market from Rofin-Sinar (NASDAQ:RSTI), Coherent (NASDAQ:COHR), and JDS Uniphase (NASDAQ: JDSU). IPG's vertically integrated production model poses a risk in such an environment should demand dwindle -- it alone among these four companies manufactures all its component parts in-house, which adds additional fixed-cost pressures that could tank margins in the event of a supply glut.

Fool writer Erik Eason has highlighted this issue by pointing out that IPG's capital expenditures are more than three times higher as a percentage of its sales than either Coherent's or Rofin-Sinar's. This higher spending places IPG at a bit of a research disadvantage, since both competitors can (and do) spend more of their revenue on R&D. However, IPG's focus on fiber lasers has been rewarded with a top- and bottom-line growth rate far greater than either of its competitors:

A tighter focus certainly has its advantages, but despite this superior performance, IPG's P/E ratio is now the lowest  of the three companies. On the other hand, its price-to-free-cash-flow ratio of 31 remains elevated well above either Coherent's P/FCF ratio  of 25 or Rofin-Sinar's P/FCF of 18. On this metric, at least, IPG retains its growth premium over its peers, but it will need to sustain those higher growth rates going forward to avoid becoming yet another former growth stock going nowhere.

Putting the pieces together
Today, IPG Photonics has many of the qualities that make up a great stock, but no stock is truly perfect. Digging deeper can help you uncover the answers you need to make a great buy -- or to stay away from a stock that's going nowhere.

Warren Buffett: This new technology is a "real threat"
At the recent Berkshire Hathaway annual meeting, Warren Buffett admitted this emerging technology is threatening his biggest cash-cow. While Buffett shakes in his billionaire-boots, only a few investors are embracing this new market which experts say will be worth over $2 trillion. Find out how you can cash in on this technology before the crowd catches on, by jumping onto one company that could get you the biggest piece of the action. Click here to access a FREE investor alert on the company we're calling the "brains behind" the technology.

4 in 5 Americans Are Ignoring Buffett's Warning

Don't be one of them.

Jun 12, 2015 at 5:01PM

Admitting fear is difficult.

So you can imagine how shocked I was to find out Warren Buffett recently told a select number of investors about the cutting-edge technology that's keeping him awake at night.

This past May, The Motley Fool sent 8 of its best stock analysts to Omaha, Nebraska to attend the Berkshire Hathaway annual shareholder meeting. CEO Warren Buffett and Vice Chairman Charlie Munger fielded questions for nearly 6 hours.
The catch was: Attendees weren't allowed to record any of it. No audio. No video. 

Our team of analysts wrote down every single word Buffett and Munger uttered. Over 16,000 words. But only two words stood out to me as I read the detailed transcript of the event: "Real threat."

That's how Buffett responded when asked about this emerging market that is already expected to be worth more than $2 trillion in the U.S. alone. Google has already put some of its best engineers behind the technology powering this trend. 

The amazing thing is, while Buffett may be nervous, the rest of us can invest in this new industry BEFORE the old money realizes what hit them.

KPMG advises we're "on the cusp of revolutionary change" coming much "sooner than you think."

Even one legendary MIT professor had to recant his position that the technology was "beyond the capability of computer science." (He recently confessed to The Wall Street Journal that he's now a believer and amazed "how quickly this technology caught on.")

Yet according to one J.D. Power and Associates survey, only 1 in 5 Americans are even interested in this technology, much less ready to invest in it. Needless to say, you haven't missed your window of opportunity. 

Think about how many amazing technologies you've watched soar to new heights while you kick yourself thinking, "I knew about that technology before everyone was talking about it, but I just sat on my hands." 

Don't let that happen again. This time, it should be your family telling you, "I can't believe you knew about and invested in that technology so early on."

That's why I hope you take just a few minutes to access the exclusive research our team of analysts has put together on this industry and the one stock positioned to capitalize on this major shift.
