Which Is the Better Buy: SanDisk or Micron Technology?

Both companies' shares are flying high. Which one should investors buy?

May 15, 2014 at 4:00PM

Shares of Micron Technology (NASDAQ:MU) hit a new 52-week high earlier this week. The company's peer, SanDisk (NASDAQ:SNDK), is trading at a similarly unseen price this week. Despite the high price tags, both companies offer investors a great opportunity to get in on the rapidly growing NAND flash memory market, which is why the market is bidding up these stock prices.

Investors trying to choose between SanDisk and Micron Technology face a tough decision. Which is the better buy, SanDisk or Micron?

Why these companies are worth a look
On Micron's second-quarter conference call, CEO Mark Durcan expressed the company's expectations that the NAND industry will grow in the low-40% range for 2014. Over the next five years, the company expects the market to grow at a rate in the high-30% to low-40% range.

Durcan goes on to note that industry capacity can cause volatility in the market. Determining proper capacity is often difficult for companies as they try to match long-term outlooks with short-term demand.

Most recently, a fire at SK Hynix's Wuxi facilities put a damper on the company's production levels. While the company expects to return to its pre-fire production levels this quarter, stagnated NAND capacity at SK is good for both SanDisk and Micron.

Micron, meanwhile, increased its NAND capacity by converting its Singapore facility from DRAM to NAND. SanDisk, too, is steadily investing in increasing capacity. Capital expenditures at the latter company, however, are decreasing.

Let's look at some numbers

Gross Margin (ttm)



Net Income (ttm)

Micron looks like a better buy than SanDisk. It's converting revenue into cash more efficiently, and it's priced more attractively in terms of future earnings, sales, and free cash flow. However, SanDisk does have one advantage -- it's growing faster than Micron. Over the next five years, analysts expect SanDisk to grow earnings at a rate of 18.75%. Comparatively, they expect Micron to grow earnings at a rate of just 10.25%.

As a result, SanDisk offers a slightly more attractive PEG ratio of 0.75 compared to Micron's PEG of 0.84. With both stocks trading below PEG ratios of 1, it's a strong indication the market is undervaluing the potential growth of both company's earnings.

SanDisk's significantly higher gross margin is worth investigating as well. The company posted record gross margin levels for the first quarter with 51% margin on its sales. Management attributed the boost to stronger SSD product mix.

Comparatively, Micron achieved a gross margin of 34% last quarter, and trade NAND was actually a drag on its overall margins. This is an indication that SanDisk's technology may have more of a moat around it, as the company is better able to control the decline in price per gigabyte. Of course, part of SanDisk's focus in the recent past has been the high-end NAND market, so the fact that it has higher gross margins shouldn't be surprising.

The better buy
Although both stocks are worth owning, Micron seems to offer better value for the price right now. For those particularly interested in strong growth, SanDisk presents its advantages, but it's a bit more risky at this price, and doesn't quite offer the value of Micron.

With Micron, investors gain the advantage of diversifying into the DRAM market, an equally impressive growth story. Micron expects the DRAM industry to grow in the 20%-30% range annually over the next five years. As part of two growing industries, and priced where it is, Micron looks like the better buy.

Are you ready to profit from this $14.4 trillion revolution?
Let's face it, every investor wants to get in on revolutionary ideas before they hit it big. Like buying PC-maker Dell in the late 1980s, before the consumer computing boom. Or purchasing stock in e-commerce pioneer Amazon.com in the late 1990s, when it was nothing more than an upstart online bookstore. The problem is, most investors don't understand the key to investing in hyper-growth markets. The real trick is to find a small-cap "pure-play" and then watch as it grows in EXPLOSIVE lockstep with its industry. Our expert team of equity analysts has identified one stock that's poised to produce rocket-ship returns with the next $14.4 TRILLION industry.

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.

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.
