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, National Grid plc (LON:NG.) shareholders have seen the share price rise 31% over three years, well in excess of the market decline (8.0%, not including dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 23% in the last year , including dividends .
So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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, National Grid achieved compound earnings per share growth of 11% per year. We note that the 10% yearly (average) share price gain isn't too far from the EPS growth rate. Coincidence? Probably not. This suggests that sentiment and expectations have not changed drastically. Rather, the share price has approximately tracked EPS growth.

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 incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of National Grid, it has a TSR of 53% 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
We're pleased to report that National Grid shareholders have received a total shareholder return of 23% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 8% 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. 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.
