One simple way to benefit from the stock market is to buy an index fund. But if you choose individual stocks with prowess, you can make superior returns. Just take a look at Cactus, Inc. (NYSE:WHD), which is up 59%, over three years, soundly beating the market return of 15% (not including dividends).

The past week has proven to be lucrative for Cactus investors, so let's see if fundamentals drove the company's three-year performance.

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.

Cactus was able to grow its EPS at 31% per year over three years, sending the share price higher. The average annual share price increase of 17% is actually lower than the EPS growth. So it seems investors have become more cautious about the company, over time.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

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 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Cactus the TSR over the last 3 years was 64%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Cactus shareholders are down 18% for the year (even including dividends), but the market itself is up 22%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 6% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. If you would like to research Cactus in more detail then you might want to take a look at whether insiders have been buying or selling shares in the company.
