To the annoyance of some shareholders, Sincere Watch (Hong Kong) Limited (HKG:444) shares are down a considerable 33% in the last month, which continues a horrid run for the company. For any long-term shareholders, the last month ends a year to forget by locking in a 69% share price decline.

Even after such a large drop in price, you could still be forgiven for feeling indifferent about Sincere Watch (Hong Kong)'s P/S ratio of 0.5x, since the median price-to-sales (or "P/S") ratio for the Retail Distributors industry in Hong Kong is also close to 0.7x. While this might not raise any eyebrows, if the P/S ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

How Sincere Watch (Hong Kong) Has Been Performing

The revenue growth achieved at Sincere Watch (Hong Kong) over the last year would be more than acceptable for most companies. It might be that many expect the respectable revenue performance to wane, which has kept the P/S from rising. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

How Is Sincere Watch (Hong Kong)'s Revenue Growth Trending?

Sincere Watch (Hong Kong)'s P/S ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the industry.

Retrospectively, the last year delivered an exceptional 28% gain to the company's top line. Still, revenue has fallen 7.9% in total from three years ago, which is quite disappointing. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenues over that time.

In contrast to the company, the rest of the industry is expected to grow by 32% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

In light of this, it's somewhat alarming that Sincere Watch (Hong Kong)'s P/S sits in line with the majority of other companies. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh on the share price eventually.

What Does Sincere Watch (Hong Kong)'s P/S Mean For Investors?

Sincere Watch (Hong Kong)'s plummeting stock price has brought its P/S back to a similar region as the rest of the industry. We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

Our look at Sincere Watch (Hong Kong) revealed its shrinking revenues over the medium-term haven't impacted the P/S as much as we anticipated, given the industry is set to grow. Even though it matches the industry, we're uncomfortable with the current P/S ratio, as this dismal revenue performance is unlikely to support a more positive sentiment for long. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.

And what about other risks? Every company has them, and we've spotted 3 warning signs for Sincere Watch (Hong Kong) (of which 2 make us uncomfortable!) you should know about.
