Despite shrinking by US$147m in the past week, Powell Industries (NASDAQ:POWL) shareholders are still up 376% over 5 years

Powell Industries, Inc. (NASDAQ:POWL) shareholders might be concerned after seeing the share price drop 26% in the last month. But over five years returns have been remarkably great. Indeed, the share price is up a whopping 309% in that time. Arguably, the recent fall is to be expected after such a strong rise. But the real question is whether the business fundamentals can improve over the long term.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

Check out our latest analysis for Powell Industries

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the last half decade, Powell Industries became profitable. Sometimes, the start of profitability is a major inflection point that can signal fast earnings growth to come, which in turn justifies very strong share price gains. 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 Powell Industries share price is up 257% in the last three years. In the same period, EPS is up 77% per year. This EPS growth is higher than the 53% average annual increase in the share price over the same three years. Therefore, it seems the market has moderated its expectations for growth, somewhat.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Powell Industries' TSR for the last 5 years was 376%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's good to see that Powell Industries has rewarded shareholders with a total shareholder return of 209% in the last twelve months. That's including the dividend. That gain is better than the annual TSR over five years, which is 37%. Therefore it seems like sentiment around the company has been positive lately. 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.
