Investing in Armstrong World Industries (NYSE:AWI) five years ago would have delivered you a 137% gain

When you buy a stock there is always a possibility that it could drop 100%. But when you pick a company that is really flourishing, you can make more than 100%. For instance, the price of Armstrong World Industries, Inc. (NYSE:AWI) stock is up an impressive 125% over the last five years. In more good news, the share price has risen 19% in thirty days. But this could be related to good market conditions -- stocks in its market are up 13% in the last month.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During the last half decade, Armstrong World Industries became profitable. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here. Given that the company made a profit three years ago, but not five years ago, it is worth looking at the share price returns over the last three years, too. We can see that the Armstrong World Industries share price is up 95% in the last three years. In the same period, EPS is up 16% per year. This EPS growth is lower than the 25% average annual increase in the share price over three years. So it's fair to assume the market has a higher opinion of the business than it did three years ago.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Armstrong World Industries, it has a TSR of 137% for the last 5 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's good to see that Armstrong World Industries has rewarded shareholders with a total shareholder return of 41% in the last twelve months. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 19% per year), it would seem that the stock's performance has improved in recent times. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
