It hasn't been the best quarter for ISDN Holdings Limited (SGX:I07) shareholders, since the share price has fallen 14% in that time. Looking further back, the stock has generated good profits over five years. Its return of 70% has certainly bested the market return!

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During five years of share price growth, ISDN Holdings actually saw its EPS drop 13% per year.

This means it's unlikely the market is judging the company based on earnings growth. 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.

In contrast revenue growth of 7.3% per year is probably viewed as evidence that ISDN Holdings is growing, a real positive. In that case, the company may be sacrificing current earnings per share to drive growth.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for ISDN Holdings the TSR over the last 5 years was 89%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

While the broader market lost about 0.7% in the twelve months, ISDN Holdings shareholders did even worse, losing 13% (even including dividends). Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. 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. It's always interesting to track share price performance over the longer term. But to understand ISDN Holdings better, we need to consider many other factors.
