NOV (NYSE:NOV) shareholders have earned a 6.9% CAGR over the last three years

By buying an index fund, investors can approximate the average market return. But many of us dare to dream of bigger returns, and build a portfolio ourselves. Just take a look at NOV Inc. (NYSE:NOV), which is up 18%, over three years, soundly beating the market return of 15% (not including dividends).

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 way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During three years of share price growth, NOV moved from a loss to profitability. That would generally be considered a positive, so we'd expect the share price to be up.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for NOV the TSR over the last 3 years was 22%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

NOV shareholders gained a total return of 19% during the year. But that was short of the market average. On the bright side, that's still a gain, and it is certainly better than the yearly loss of about 2% endured over half a decade. It could well be that the business is stabilizing. 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. Take risks, for example - NOV has 2 warning signs (and 1 which is a bit concerning) we think you should know about.
