The three-year loss for Chunbo (KOSDAQ:278280) shareholders likely driven by its shrinking earnings

Chunbo Co., Ltd. (KOSDAQ:278280) shareholders will doubtless be very grateful to see the share price up 52% in the last quarter. But that is meagre solace in the face of the shocking decline over three years. The share price has sunk like a leaky ship, down 72% in that time. So we're relieved for long term holders to see a bit of uplift. Only time will tell if the company can sustain the turnaround.

While the last three years has been tough for Chunbo shareholders, this past week has shown signs of promise. So let's look at the longer term fundamentals and see if they've been the driver of the negative returns.

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.

Chunbo became profitable within the last five years. 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.

Arguably the revenue decline of 35% per year has people thinking Chunbo is shrinking. And that's not surprising, since it seems unlikely that EPS growth can continue for long in the absence of revenue growth.

A Different Perspective

Chunbo shareholders are up 70% for the year. But that was short of the market average. But at least that's still a gain! Over five years the TSR has been a reduction of 10% per year, over five years. 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 Chunbo better, we need to consider many other factors. Even so, be aware that Chunbo is showing 3 warning signs in our investment analysis , you should know about...
