Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. And in our experience, buying the right stocks can give your wealth a significant boost. For example, the Iljin Power Co., Ltd. (KOSDAQ:094820) share price is up 96% in the last 5 years, clearly besting the market return of around 37% (ignoring dividends).

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. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Iljin Power's earnings per share are down 32% per year, despite strong share price performance over five years.

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 are not particularly impressed by the annual compound revenue growth of 2.6% over five years. 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 Iljin Power the TSR over the last 5 years was 132%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

Iljin Power shareholders are down 4.9% for the year (even including dividends), but the market itself is up 16%. 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 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. 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.
