The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But when you pick a company that is really flourishing, you can make more than 100%. For instance, the price of Industrial Bank of Korea (KRX:024110) stock is up an impressive 122% over the last five years.
With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.
There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.
Over half a decade, Industrial Bank of Korea managed to grow its earnings per share at 12% a year. This EPS growth is slower than the share price growth of 17% per year, over the same period. This suggests that market participants hold the company in higher regard, these days. That's not necessarily surprising considering the five-year track record of earnings growth.

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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, Industrial Bank of Korea's TSR for the last 5 years was 216%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!
Industrial Bank of Korea shareholders gained a total return of 57% during the year. But that return falls short of the market. On the bright side, that's still a gain, and it's actually better than the average return of 26% over half a decade This suggests the company might be improving over time. 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.
