By buying an index fund, you can roughly match the market return with ease. But if you buy good businesses at attractive prices, your portfolio returns could exceed the average market return. For example, the Tharisa plc (JSE:THA) share price is up 57% in the last three years, clearly besting the market return of around 10% (not including dividends).

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders returns.

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.

Tharisa was able to grow its EPS at 53% per year over three years, sending the share price higher. This EPS growth is higher than the 16% average annual increase in the share price. Therefore, it seems the market has moderated its expectations for growth, somewhat. We'd venture the lowish P/E ratio of 2.92 also reflects the negative sentiment around the stock.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money. Dive deeper into the earnings by checking this interactive graph of Tharisa's earnings, revenue and cash flow.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Tharisa, it has a TSR of 71% for the last 3 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

While the broader market gained around 5.6% in the last year, Tharisa shareholders lost 18% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 8% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
