3 Stocks That Will Probably Make Huge Moves This Week

A high short interest, plus upcoming earnings announcements, should have these stocks making big moves in the coming days.

Jan 19, 2014 at 7:00AM

Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

Making investment decisions based on short-term movements in the stock market is not the tried and true way to financial security. Focusing on the long-term trends -- and knowing what variables truly matter over the long run -- is a much more surefire, if boring, approach.

"So why even write an article about big movers for the week ahead?" you may ask. The answer is that we're all human, and no matter how much we may believe to the contrary, we're liable to make emotional decisions when we see our stocks making huge moves.

This article is meant to prepare investors in three companies for big moves in the week ahead. The reason these three companies are likely to be volatile is that they're all highly shorted, and they're reporting earnings this week.

Last week, there was only one such stock identified. But sure enough, it popped as much as 10% following earnings. Here are this week's three stocks to watch:


% Shares Short


Expected Revenue (in Millions)

Expected EPS

InvenSense (NYSE:INVN)





Advanced Micro Devices (NASDAQ:AMD)





Fusion-io (NYSE:FIO)

This company makes micro-electro-mechanical system gyroscopes. While a lot of techies out there might know what that means, the layman's version is this: The company makes the technology that allows devices to know when and how they are being moved. The easiest and earliest reference point would be Nintendo's first-generation controller.

Shares have more than doubled since last April, which has some investors betting that a drop is in the near future. But more importantly, the company has been engaged in a lengthy court battle with STMicroelectronics for a while now. Beyond needing to continue out-innovating STM, if InvenSense were to lose the case, it could have negative consequences for investors.

Advanced Micro Devices
AMD is a worldwide semiconductor company that focuses on servers, PCs, and mobile devices -- though it was very late to the scene for mobile. Shares of the company are up about 80% since bottoming out last April, but they still sit almost 46% lower than they were in early 2012.

The key to AMD's future is twofold. The company's chips were selected to be in Sony's PS4 and Microsoft's Xbox One. Strong sales here would definitely be a boost to the company. But the second half of the equation is that the PC market needs to improve moving forward, as the prevalence of mobile devices has continually eaten away at the once-ubiquitous PC.

This company with a funny name is in the business of both hardware and software to enable data storage. Over the past year and a half, shares have fallen more than 70%. The problem hasn't necessarily been the quality of Fusion-io's products, but its inability to compete with others on price.

Specifically, EMC has roughly $10 billion in cash on its balance sheet; Fusion-io has only about 2% of that amount, with $225 million. That's important, because EMC can offer its memory products for a steep discount and still survive, but if Fusion-io wants to match those prices, it will be losing money it can't afford to lose.

Stay focused on the long term
As I said at the beginning, you won't make it rich by betting on short-term movements.  As every savvy investor knows, stock market gurus like Warren Buffett didn't make billions by betting on half-baked stocks. He isolated his best few ideas, bet big, and rode them to riches, hardly ever selling. You deserve the same.

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.
