Investors in Oriental Union Chemical (TWSE:1710) from three years ago are still down 26%, even after 12% gain this past week

Oriental Union Chemical Corporation (TWSE:1710) shareholders should be happy to see the share price up 12% in the last week. But that doesn't change the fact that the returns over the last three years have been less than pleasing. In fact, the share price is down 31% in the last three years, falling well short of the market return.

On a more encouraging note the company has added NT$1.4b to its market cap in just the last 7 days, so let's see if we can determine what's driven the three-year loss for shareholders.

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).

Over the three years that the share price declined, Oriental Union Chemical's earnings per share (EPS) dropped significantly, falling to a loss. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. However, we can say we'd expect to see a falling share price in this scenario.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Oriental Union Chemical, it has a TSR of -26% 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 Oriental Union Chemical had a tough year, with a total loss of 19% (including dividends), against a market gain of about 34%. 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 4% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
