Investors in Dunelm Group (LON:DNLM) have unfortunately lost 11% over the last three years

Many investors define successful investing as beating the market average over the long term. But if you try your hand at stock picking, your risk returning less than the market. We regret to report that long term Dunelm Group plc (LON:DNLM) shareholders have had that experience, with the share price dropping 31% in three years, versus a market return of about 16%.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

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...' 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.

Although the share price is down over three years, Dunelm Group actually managed to grow EPS by 11% per year in that time. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.

It's worth taking a look at other metrics, because the EPS growth doesn't seem to match with the falling share price.

We note that the dividend seems healthy enough, so that probably doesn't explain the share price drop. We like that Dunelm Group has actually grown its revenue over the last three years. But it's not clear to us why the share price is down. It might be worth diving deeper into the fundamentals, lest an opportunity goes begging.

We like that insiders have been buying shares in the last twelve months. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Dunelm Group's TSR for the last 3 years was -11%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 7.4% in the last year, Dunelm Group shareholders lost 7.0% (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 10% 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. 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.
