Shareholders in Ko Yo Chemical (Group) (HKG:827) have lost 54%, as stock drops 12% this past week

It is doubtless a positive to see that the Ko Yo Chemical (Group) Limited (HKG:827) share price has gained some 38% in the last three months. But that can't change the reality that over the longer term (five years), the returns have been really quite dismal. The share price has failed to impress anyone , down a sizable 54% during that time. So is the recent increase sufficient to restore confidence in the stock? Not yet. Of course, this could be the start of a turnaround.

With the stock having lost 12% in the past week, it's worth taking a look at business performance and seeing if there's any red flags.

Given that Ko Yo Chemical (Group) didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. When a company doesn't make profits, we'd generally expect to see good revenue growth. That's because it's hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

In the last half decade, Ko Yo Chemical (Group) saw its revenue increase by 2.8% per year. That's not a very high growth rate considering it doesn't make profits. It's likely this weak growth has contributed to an annualised return of 9% for the last five years. We'd want to see proof that future revenue growth is likely to be significantly stronger before getting too interested in Ko Yo Chemical (Group).
