Even though EM-Tech.CO (KOSDAQ:091120) has lost ₩67b market cap in last 7 days, shareholders are still up 198% over 5 years

The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, you can make far more than 100% on a really good stock. For example, the EM-Tech.CO., LTD. (KOSDAQ:091120) share price has soared 183% in the last half decade. Most would be very happy with that. In the last week shares have slid back 14%.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

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.

During five years of share price growth, EM-Tech.CO actually saw its EPS drop 5.2% per year.

Essentially, it doesn't seem likely that investors are focused on EPS. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

We doubt the modest 0.4% dividend yield is attracting many buyers to the stock. The revenue growth of 1.6% per year hardly seems impressive. So why is the share price up? It's not immediately obvious to us, but a closer look at the company's progress over time might yield answers.

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 incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for EM-Tech.CO the TSR over the last 5 years was 198%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Investors in EM-Tech.CO had a tough year, with a total loss of 52% (including dividends), against a market gain of about 13%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 24% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
