As Wilmar International (SGX:F34) ascends 4.1% this past week, investors may now be noticing the company's three-year earnings growth

Many investors define successful investing as beating the market average over the long term. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. Unfortunately, that's been the case for longer term Wilmar International Limited (SGX:F34) shareholders, since the share price is down 17% in the last three years, falling well short of the market return of around 26%.

While the stock has risen 4.1% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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).

Although the share price is down over three years, Wilmar International actually managed to grow EPS by 8.1% per year in that time. This is quite a puzzle, and suggests there might be something temporarily buoying the share price. Or else the company was over-hyped in the past, and so its growth has disappointed.

Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

Given the healthiness of the dividend payments, we doubt that they've concerned the market. It's good to see that Wilmar International has increased its revenue over the last three years. If the company can keep growing revenue, there may be an opportunity for investors. You might have to dig deeper to understand the recent share price weakness.

It's good to see that there was some significant insider buying in the last three months. That's a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. In the case of Wilmar International, it has a TSR of -5.8% for the last 3 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Investors in Wilmar International had a tough year, with a total loss of 4.7% (including dividends), against a market gain of about 2.2%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 6% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. It's always interesting to track share price performance over the longer term. But to understand Wilmar International better, we need to consider many other factors.
