When you buy and hold a stock for the long term, you definitely want it to provide a positive return. But more than that, you probably want to see it rise more than the market average. But WD-40 Company (NASDAQ:WDFC) has fallen short of that second goal, with a share price rise of 46% over five years, which is below the market return. However, more recent buyers should be happy with the increase of 43% over the last year.

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

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.

Over half a decade, WD-40 managed to grow its earnings per share at 1.6% a year. This EPS growth is slower than the share price growth of 8% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of growth. This optimism is visible in its fairly high P/E ratio of 48.89.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money. Dive deeper into the earnings by checking this interactive graph of WD-40's earnings, revenue and cash flow.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for WD-40 the TSR over the last 5 years was 57%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's nice to see that WD-40 shareholders have received a total shareholder return of 46% over the last year. And that does include the dividend. That's better than the annualised return of 9% over half a decade, implying that the company is doing better recently. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time.
