Alcoa Inc: Transformation or Mean Reversion?

Is Alcoa's head-scratching rally sustainable?

Jul 18, 2014 at 11:00AM

Alcoa, Inc (NYSE:AA) is on fire. The aluminum producer's stock is up a sizzling 54% year to date, making Alcoa one of the best performers in the S&P 500. According to pundits and analysts alike, Alcoa is a new and exciting value-added company with significant higher-margin growth ahead of it. 

But given Alcoa's pricey forward price to earnings ratio as well as analysts' history of adjusting their commentary to the latest trend, many investors understandably question whether the rally is sustainable. 

Is Alcoa really a new company, or is it the same company with margins reverting back to a normalized mean?

Signs of transformation
There are signs that Alcoa is legitimately transforming itself.  In its latest earnings report, the aluminum producer's value added divisions did grow significantly. Alcoa's engineered products and solutions division, for example, grew by 6% year over year and reported a quarterly record of $204 million in after tax operating income.

Given the healthy expected growth of Alcoa's value-added end markets such as aerospace and North American commercial transportation, one can make the argument that the value-added growth will continue for a while. If that growth continues, Alcoa margins will increase, and given the differentiated nature of the value added products, those margins will likely be more sustainable than Alcoa's current cut-throat commodity business. 

Moreover, Alcoa management is actively trying to speed up the process by acquiring value-added companies such as Firth Rixson, a maker of aerospace jet engine components.

With the rally of Alcoa's stock, the market itself is playing its part by giving management the mandate to do future value added acquisitions. Because of the mandate, Alcoa may do future value-added acquisitions as well. 

1 sign of mean reversion
Those things being said, there is a sign that Alcoa is just reverting to a normalized mean. Aluminum margins are, specifically, climbing as Chinese aluminum oversupply no longer haunts the marketplace. In Alcoa's second quarter earnings report, for example, Alcoa's primary metals unit reported an after-tax operating income of $97 million versus an after-tax operating income of negative $32 million last year. This vast improvement explains to a large degree why Alcoa turned a profit this quarter. 

With global aluminum demand expected to grow by 7% and a projected global deficit of aluminum this year, margins should be better for all companies in the aluminum industry. Indeed, other aluminum companies are also doing well. Century Aluminum (NASDAQ:CENX), for example, is up 68% year to date.

The bottom line
The reason for the puzzling rally is likely both that Alcoa's aluminum margins are reverting back to a normalized mean and that the company is legitimately transforming itself into a more value added company. And while mean reversion is not necessarily good news given that margins may trend lower as say when Chinese aluminum companies increase their production, the value added segment is likely to make a bigger and bigger part of Alcoa's profits moving forward.

Over time, the combination of organic value-added growth along with possible future acquisitions will transform Alcoa.  If Alcoa can achieve that transformation without overpaying for its future acquisitions while at the same time containing costs, Alcoa's rally will likely be sustainable and could continue.

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

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, 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
