Investing in United Microelectronics (TWSE:2303) five years ago would have delivered you a 220% gain

While United Microelectronics Corporation (TWSE:2303) shareholders are probably generally happy, the stock hasn't had particularly good run recently, with the share price falling 13% in the last quarter. But that doesn't change the fact that the returns over the last five years have been very strong. It's fair to say most would be happy with 145% the gain in that time. Generally speaking the long term returns will give you a better idea of business quality than short periods can. The more important question is whether the stock is too cheap or too expensive today.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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 half a decade, United Microelectronics managed to grow its earnings per share at 40% a year. This EPS growth is higher than the 20% average annual increase in the share price. So it seems the market isn't so enthusiastic about the stock these days. The reasonably low P/E ratio of 10.70 also suggests market apprehension.

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 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, United Microelectronics' TSR for the last 5 years was 220%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

United Microelectronics shareholders are down 12% for the year (even including dividends), but the market itself is up 30%. 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 26%, 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 United Microelectronics better, we need to consider many other factors.
