Fonterra Co-operative Group Limited (NZSE:FCG) shareholders should be happy to see the share price up 27% in the last quarter. But over the last half decade, the stock has not performed well. In fact, the share price is down 25%, which falls well short of the return you could get by buying an index fund.

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.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During five years of share price growth, Fonterra Co-operative Group moved from a loss to profitability. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics might give us a better handle on how its value is changing over time.

The steady dividend doesn't really explain why the share price is down. It's not immediately clear to us why the stock price is down but further research might provide some answers.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Fonterra Co-operative Group the TSR over the last 5 years was 13%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

It's nice to see that Fonterra Co-operative Group shareholders have received a total shareholder return of 22% over the last year. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 2% per year), it would seem that the stock's performance has improved in recent times. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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.
