The total return for AMPACS (TWSE:6743) investors has risen faster than earnings growth over the last five years

The last three months have been tough on AMPACS Corporation (TWSE:6743) shareholders, who have seen the share price decline a rather worrying 38%. On the bright side the share price is up over the last half decade. In that time, it is up 56%, which isn't bad, but is below the market return of 127%.

Although AMPACS has shed NT$811m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

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 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 the five years of share price growth, AMPACS moved from a loss to profitability. That's generally thought to be a genuine positive, so investors may expect to see an increasing share price.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, AMPACS' TSR for the last 5 years was 64%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

AMPACS shareholders are down 22% for the year (even including dividends), but the market itself is up 31%. 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. Longer term investors wouldn't be so upset, since they would have made 10%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
