Tysan Holdings Limited (HKG:687) shareholders that were waiting for something to happen have been dealt a blow with a 26% share price drop in the last month. Longer-term shareholders would now have taken a real hit with the stock declining 9.2% in the last year.

Even after such a large drop in price, you could still be forgiven for feeling indifferent about Tysan Holdings' P/S ratio of 0.3x, since the median price-to-sales (or "P/S") ratio for the Construction industry in Hong Kong is about the same. 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 Tysan Holdings Has Been Performing

Tysan Holdings certainly has been doing a great job lately as it's been growing its revenue at a really rapid pace. The P/S is probably moderate because investors think this strong revenue growth might not be enough to outperform the broader industry in the near future. Those who are bullish on Tysan Holdings will be hoping that this isn't the case, so that they can pick up the stock at a lower valuation.

Do Revenue Forecasts Match The P/S Ratio?

The only time you'd be comfortable seeing a P/S like Tysan Holdings' is when the company's growth is tracking the industry closely.

If we review the last year of revenue growth, the company posted a terrific increase of 36%. Although, its longer-term performance hasn't been as strong with three-year revenue growth being relatively non-existent overall. So it appears to us that the company has had a mixed result in terms of growing revenue over that time.

Comparing the recent medium-term revenue trends against the industry's one-year growth forecast of 13% shows it's noticeably less attractive.

In light of this, it's curious that Tysan Holdings' P/S sits in line with the majority of other companies. Apparently many investors in the company are less bearish than recent times would indicate and aren't willing to let go of their stock right now. Maintaining these prices will be difficult to achieve as a continuation of recent revenue trends is likely to weigh down the shares eventually.

The Bottom Line On Tysan Holdings' P/S

Following Tysan Holdings' share price tumble, its P/S is just clinging on to the industry median P/S. It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Tysan Holdings revealed its poor three-year revenue trends aren't resulting in a lower P/S as per our expectations, given they look worse than current industry outlook. When we see weak revenue with slower than industry growth, we suspect the share price is at risk of declining, bringing the P/S back in line with expectations. If recent medium-term revenue trends continue, the probability of a share price decline will become quite substantial, placing shareholders at risk.
