Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. And while active stock picking involves risks (and requires diversification) it can also provide excess returns. For example, the Clarkson PLC (LON:CKN) share price is up 61% in the last 5 years, clearly besting the market return of around 25% (ignoring dividends).

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

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 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.

During the five years of share price growth, Clarkson moved from a loss to profitability. That would generally be considered a positive, so we'd hope to see the share price to rise. Since the company was unprofitable five years ago, but not three years ago, it's worth taking a look at the returns in the last three years, too. In fact, the Clarkson stock price is 2.2% lower in the last three years. During the same period, EPS grew by 19% each year. So there seems to be a mismatch between the positive EPS growth and the change in the share price, which is down -0.7% per year.

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of 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. We note that for Clarkson the TSR over the last 5 years was 90%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Investors in Clarkson had a tough year, with a total loss of 22% (including dividends), against a market gain of about 10%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 14%, each year, over five years. 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.
