For many, the main point of investing in the stock market is to achieve spectacular returns. And highest quality companies can see their share prices grow by huge amounts. To wit, the KLA Corporation (NASDAQ:KLAC) share price has soared 505% over five years. This just goes to show the value creation that some businesses can achieve. It's also good to see the share price up 35% over the last quarter. It really delights us to see such great share price performance for investors.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

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. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During five years of share price growth, KLA achieved compound earnings per share (EPS) growth of 17% per year. This EPS growth is slower than the share price growth of 43% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of growth.

It is of course excellent to see how KLA has grown profits over the years, but the future is more important for shareholders. It might be well worthwhile taking a look at our free report on how its financial position has changed over time.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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 KLA, it has a TSR of 551% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We're pleased to report that KLA shareholders have received a total shareholder return of 99% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 45% per year), it would seem that the stock's performance has improved in recent times. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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. Consider risks, for instance. Every company has them, and we've spotted 1 warning sign for KLA you should know about.
