Many investors define successful investing as beating the market average over the long term. But the risk of stock picking is that you will likely buy under-performing companies. We regret to report that long term Grainger plc (LON:GRI) shareholders have had that experience, with the share price dropping 23% in three years, versus a market return of about 16%.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

View our latest analysis for Grainger

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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.

Over the three years that the share price declined, Grainger's earnings per share (EPS) dropped significantly, falling to a loss. Extraordinary items contributed to this situation. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. But it's safe to say we'd generally expect the share price to be lower as a result!

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. We note that for Grainger the TSR over the last 3 years was -18%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Grainger shareholders are up 7.4% for the year (even including dividends). But that return falls short of the market. The silver lining is that the gain was actually better than the average annual return of 3% per year over five year. This suggests the company might be improving over time. 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. Like risks, for instance. Every company has them, and we've spotted  2 warning signs for Grainger  (of which 1 is concerning!) you should know about.
