For many, the main point of investing is to generate higher returns than the overall market. But in any portfolio, there will be mixed results between individual stocks. At this point some shareholders may be questioning their investment in National Fuel Gas Company (NYSE:NFG), since the last five years saw the share price fall 19%.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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.

During five years of share price growth, National Fuel Gas moved from a loss to profitability. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics might give us a better handle on how its value is changing over time.

The steady dividend doesn't really explain why the share price is down. It's not immediately clear to us why the stock price is down but further research might provide some answers.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of National Fuel Gas, it has a TSR of -2.8% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

While the broader market gained around 28% in the last year, National Fuel Gas shareholders lost 12% (even including dividends). However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 0.5% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
