The five-year shareholder returns and company earnings persist lower as Bonne (KOSDAQ:226340) stock falls a further 13% in past week

We think intelligent long term investing is the way to go. But that doesn't mean long term investors can avoid big losses. Zooming in on an example, the Bonne Co., Ltd. (KOSDAQ:226340) share price dropped 55% in the last half decade. That's not a lot of fun for true believers. The falls have accelerated recently, with the share price down 40% in the last three months.

If the past week is anything to go by, investor sentiment for Bonne isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

Bonne became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics might give us a better handle on how its value is changing over time.

In contrast to the share price, revenue has actually increased by 14% a year in the five year 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

While the broader market gained around 7.2% in the last year, Bonne shareholders lost 18%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 9% 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. 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. Consider for instance, the ever-present spectre of investment risk.
