PSK's (KOSDAQ:319660) five-year total shareholder returns outpace the underlying earnings growth

PSK Inc. (KOSDAQ:319660) shareholders might be concerned after seeing the share price drop 12% in the last week. But that doesn't change the fact that shareholders have received really good returns over the last five years. It's fair to say most would be happy with 116% the gain in that time. We think it's more important to dwell on the long term returns than the short term returns. The more important question is whether the stock is too cheap or too expensive today. While the long term returns are impressive, we do have some sympathy for those who bought more recently, given the 37% drop, in the last year.

In light of the stock dropping 12% in the past week, we want to investigate the longer term story, and see if fundamentals have been the driver of the company's positive five-year return.

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 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.

Over half a decade, PSK managed to grow its earnings per share at 31% a year. The EPS growth is more impressive than the yearly share price gain of 17% over the same period. So it seems the market isn't so enthusiastic about the stock these days. This cautious sentiment is reflected in its (fairly low) P/E ratio of 7.16.

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 incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, PSK's TSR for the last 5 years was 133%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market lost about 9.4% in the twelve months, PSK shareholders did even worse, losing 35% (even including dividends). However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Longer term investors wouldn't be so upset, since they would have made 18%, 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.
