Spirox's (TWSE:3055) earnings growth rate lags the 25% CAGR delivered to shareholders

The Spirox Corporation (TWSE:3055) share price has had a bad week, falling 10%. But that doesn't change the fact that the returns over the last five years have been very strong. It's fair to say most would be happy with 181% the gain in that time. We think it's more important to dwell on the long term returns than the short term returns. Ultimately business performance will determine whether the stock price continues the positive long term trend.

In light of the stock dropping 10% in the past week, we want to investigate the longer term story, and see if fundamentals have been the driver of the company's positive five-year return.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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 the last half decade, Spirox 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.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Spirox the TSR over the last 5 years was 209%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that Spirox shareholders have received a total shareholder return of 137% over one year. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 25% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. It's always interesting to track share price performance over the longer term. But to understand Spirox better, we need to consider many other factors.
