Interflex (KOSDAQ:051370 shareholders incur further losses as stock declines 10% this week, taking three-year losses to 49%

Many investors define successful investing as beating the market average over the long term. But the risk of stock picking is that you will likely buy under-performing companies. We regret to report that long term Interflex Co., Ltd. (KOSDAQ:051370) shareholders have had that experience, with the share price dropping 49% in three years, versus a market decline of about 4.4%. The more recent news is of little comfort, with the share price down 43% in a year. Even worse, it's down 13% in about a month, which isn't fun at all. Importantly, this could be a market reaction to the recently released financial results. You can check out the latest numbers in our company report.

Since Interflex has shed ₩22b from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

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 imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During five years of share price growth, Interflex moved from a loss to profitability. We would usually expect to see the share price rise as a result. So given the share price is down it's worth checking some other metrics too.

With revenue flat over three years, it seems unlikely that the share price is reflecting the top line. We're not entirely sure why the share price is dropped, but it does seem likely investors have become less optimistic about the business.

A Different Perspective

We regret to report that Interflex shareholders are down 43% for the year. Unfortunately, that's worse than the broader market decline of 8.2%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 3% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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. Consider risks, for instance.
