Investors in ISU Abxis (KOSDAQ:086890) from five years ago are still down 20%, even after 17% gain this past week

It's nice to see the ISU Abxis Co., Ltd. (KOSDAQ:086890) share price up 17% in a week. But that doesn't change the fact that the returns over the last five years have been less than pleasing. In fact, the share price is down 20%, which falls well short of the return you could get by buying an index fund.

Although the past week has been more reassuring for shareholders, they're still in the red over the last five years, so let's see if the underlying business has been responsible for the decline.

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. 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).

ISU Abxis became profitable within the last five years. Most would consider that to be a good thing, so it's counter-intuitive to see the share price declining. Other metrics might give us a better handle on how its value is changing over time.

Revenue is actually up 21% over the time period. A more detailed examination of the revenue and earnings may or may not explain why the share price languishes; there could be an opportunity.

A Different Perspective

ISU Abxis provided a TSR of 0.5% over the last twelve months. But that was short of the market average. On the bright side, that's still a gain, and it is certainly better than the yearly loss of about 4% endured over half a decade. So this might be a sign the business has turned its fortunes around. It's always interesting to track share price performance over the longer term. But to understand ISU Abxis better, we need to consider many other factors.
