Coremax (TWSE:4739) adds NT$694m to market cap in the past 7 days, though investors from a year ago are still down 27%

Coremax Corporation (TWSE:4739) shareholders should be happy to see the share price up 10% in the last week. But that doesn't change the fact that the returns over the last year have been less than pleasing. In fact, the price has declined 30% in a year, falling short of the returns you could get by investing in an index fund.

Although the past week has been more reassuring for shareholders, they're still in the red over the last year, so let's see if the underlying business has been responsible for the decline.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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).

Coremax fell to a loss making position during the year. Some investors no doubt dumped the stock as a result. We hope for shareholders' sake that the company becomes profitable again soon.

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. As it happens, Coremax's TSR for the last 1 year was -27%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Coremax shareholders are down 27% for the year (even including dividends), but the market itself is up 34%. 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 0.6%, 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.
