A Deep Dive Into 3D Systems, Part 10: Should Tilson's Short Scare You?

A famous investor is shorting shares, should investors run for cover?

Jun 26, 2014 at 10:50AM

Since the beginning of the year, 3D Systems (NYSE:DDD) shares have fallen hard. At least one investor, however, has made money. Shortly before the share price peaked, respected fund manager Whitney Tilson criticized the company for being overhyped and overpriced, and he went short against the high share price. Let's take a closer look at his critiques and see whether they hold up to scrutiny.

Points from Tilson
In Tilson's short argument from mid-January, he makes four main points. In the following, I list these in italic font and then comment upon them in plain text.

1. Tilson quotes CEO Avi Reichental as saying that "his company is 50% technology, 20% innovation and 30% awesomeness." How, Tilson asks, does one value "awesomeness"?

This is Tilson's weakest point. His comment about awesomeness does have some snark to it, and it points out the showmanship that CEOs use to talk about their companies. Maybe Reichental is more flamboyant than many such leaders, but this seems more to be a literary hook to hang the short thesis on than any serious criticism of the company as an investment.

However, another short thesis author, Citron Research, places a great deal of weight on Reichental's flamboyant nature. I'll look at Citron's points in the next two articles of this series.

2. Tilson references an early 2013 short report from Citron Research. He points out that at that time, 3D Systems was trading at 17.2 times sales, 64 times trailing EBITDA, 63 times next year's earnings estimates. Today (when Tilson was writing), it was trading even higher, at 21 times sales.

Assuming his numbers are accurate, which I have no reason to doubt (unlike some numbers in some of what Citron writes -- stay tuned), this is indeed disturbing and seems excessively high.

3. Tilson gives a review of other companies trading at such multiples over the past 20 years or so. Only a few (he cites 15) have managed to trade at such levels and be successful investments. He calls out three characteristics they share: They serve rapidly growing global markets, they have winner-take-all (or most) business models, and they have extremely "light" business models (can scale globally with very little capital).

Eleven of the 15 are Internet/software companies with very light business models, while the other four have intellectual property (three with patented drugs) that allowed gross margins of 70%-90% and net margins of 20%-30%. He says that 3D Systems meets the first criteria, but in no way meets the other two.

I'll assume that Tilson's survey of other companies and his history of 3D Systems' margins (gross margin has been above 50% in only the past couple of years, and the company's net margin is falling) are accurate for the sake of argument. The comparison is not in 3D Systems' favor, meaning that this particular company is probably not of the same caliber as those that have traded at such large multiples in the past. The company's net margin decline is also worrisome and probably indicates a company that doesn't rate such a high multiple (I discussed 3D Systems' margins here).

4. Taken all together, that is not worth paying 21 times sales.

Tilson is basically making a valuation short. These are tricky, because you have to be right on both the valuation (and he makes a decent case) and right on the timing. That is, the market has to end up agreeing with you in a reasonable amount of time without driving the share price a lot higher.

However, if the market doesn't agree with you and your short position, you can end up losing a lot of money, even multiples of what you could ever hope to gain. For instance, if you had shorted 3D Systems a year before the shares peaked -- at a price of $37.98 -- you'd still be losing money today, even after the huge drop in the share price this year. At the share price high, you would have been 154% underwater.

I don't know at what price Tilson started shorting the company's shares, but he's been right so far, since the share price peaked. Whether he'll close his short position, I also don't know, though he did say that if the company sank to a reasonable two-times-sales multiple, shares would be worth $10.

Final thoughts
Tilson's discussion of the high multiples at which 3D Systems was trading has merit -- setting aside his snarky comment about valuing awesomeness -- and his short call has been accurate since then. Whether shares will fall all the way to $10 remains to be seen.

In the next article of this series, I'll review the 2013 short report from Citron that Tilson mentioned. It's both weaker and more aggressive, and frankly, I was surprised that Tilson paid attention to it.

1 Key Step to Get Rich

Our mission at The Motley Fool is to help the world invest better. Whether that’s helping people overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we can help.

Feb 1, 2016 at 4:54PM

To be perfectly clear, this is not a get-rich action that my Foolish colleagues and I came up with. But we wouldn't argue with the approach.

A 2015 Business Insider article titled, "11 websites to bookmark if you want to get rich" rated The Motley Fool as the #1 place online to get smarter about investing.

"The Motley Fool aims to build a strong investment community, which it does by providing a variety of resources: the website, books, a newspaper column, a radio [show], and [newsletters]," wrote (the clearly insightful and talented) money reporter Kathleen Elkins. "This site has something for every type of investor, from basic lessons for beginners to investing commentary on mutual funds, stock sectors, and value for the more advanced."

Our mission at The Motley Fool is to help the world invest better, so it's nice to receive that kind of recognition. It lets us know we're doing our job.

Whether that's helping the entirely uninitiated overcome their fear of stocks all the way to offering clear and successful guidance on complicated-sounding options trades, we want to provide our readers with a boost to the next step on their journey to financial independence.

Articles and beyond

As Business Insider wrote, there are a number of resources available from the Fool for investors of all levels and styles.

In addition to the dozens of free articles we publish every day on our website, I want to highlight two must-see spots in your tour of fool.com.

For the beginning investor

Investing can seem like a Big Deal to those who have yet to buy their first stock. Many investment professionals try to infuse the conversation with jargon in order to deter individual investors from tackling it on their own (and to justify their often sky-high fees).

But the individual investor can beat the market. The real secret to investing is that it doesn't take tons of money, endless hours, or super-secret formulas that only experts possess.

That's why we created a best-selling guide that walks investors-to-be through everything they need to know to get started. And because we're so dedicated to our mission, we've made that available for free.

If you're just starting out (or want to help out someone who is), go to www.fool.com/beginners, drop in your email address, and you'll be able to instantly access the quick-read guide ... for free.

For the listener

Whether it's on the stationary exercise bike or during my daily commute, I spend a lot of time going nowhere. But I've found a way to make that time benefit me.

The Motley Fool offers five podcasts that I refer to as "binge-worthy financial information."

Motley Fool Money features a team of our analysts discussing the week's top business and investing stories, interviews, and an inside look at the stocks on our radar. It's also featured on several dozen radio stations across the country.

The hosts of Motley Fool Answers challenge the conventional wisdom on life's biggest financial issues to reveal what you really need to know to make smart money moves.

David Gardner, co-founder of The Motley Fool, is among the most respected and trusted sources on investing. And he's the host of Rule Breaker Investing, in which he shares his insights into today's most innovative and disruptive companies ... and how to profit from them.

Market Foolery is our daily look at stocks in the news, as well as the top business and investing stories.

And Industry Focus offers a deeper dive into a specific industry and the stories making headlines. Healthcare, technology, energy, consumer goods, and other industries take turns in the spotlight.

They're all informative, entertaining, and eminently listenable ... and I don't say that simply because the hosts all sit within a Nerf-gun shot of my desk. Rule Breaker Investing and Answers contain timeless advice, so you might want to go back to the beginning with those. The other three take their cues from the market, so you'll want to listen to the most recent first. All are available at www.fool.com/podcasts.

But wait, there's more

The book and the podcasts – both free ... both awesome – also come with an ongoing benefit. If you download the book, or if you enter your email address in the magical box at the podcasts page, you'll get ongoing market coverage sent straight to your inbox.

Investor Insights is valuable and enjoyable coverage of everything from macroeconomic events to investing strategies to our analyst's travels around the world to find the next big thing. Also free.

Get the book. Listen to a podcast. Sign up for Investor Insights. I'm not saying that any of those things will make you rich ... but Business Insider seems to think so.
