Ideally, your overall portfolio should beat the market average. But in any portfolio, there will be mixed results between individual stocks. So we wouldn't blame long term Headlam Group plc (LON:HEAD) shareholders for doubting their decision to hold, with the stock down 46% over a half decade. We also note that the stock has performed poorly over the last year, with the share price down 41%. Furthermore, it's down 23% in about a quarter. That's not much fun for holders.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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.

Headlam Group became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics may better explain the share price move.

The most recent dividend was actually lower than it was in the past, so that may have sent the share price lower. The revenue decline of 1.8% per year wouldn't have helped. So it seems weak revenue and dividend trends may have influenced the share price.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. In the case of Headlam Group, it has a TSR of -33% for the last 5 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

While the broader market lost about 5.5% in the twelve months, Headlam Group shareholders did even worse, losing 35% (even including dividends). However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 6% 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. 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.
