Sheung Moon Holdings Limited (HKG:8523) shareholders won't be pleased to see that the share price has had a very rough month, dropping 32% and undoing the prior period's positive performance. Longer-term shareholders will rue the drop in the share price, since it's now virtually flat for the year after a promising few quarters.

Even after such a large drop in price, you could still be forgiven for thinking Sheung Moon Holdings is a stock not worth researching with a price-to-sales ratios (or "P/S") of 1x, considering almost half the companies in Hong Kong's Construction industry have P/S ratios below 0.3x. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/S.

What Does Sheung Moon Holdings' Recent Performance Look Like?

Sheung Moon Holdings certainly has been doing a great job lately as it's been growing its revenue at a really rapid pace. The P/S ratio is probably high because investors think this strong revenue growth will be enough to outperform the broader industry in the near future. If not, then existing shareholders might be a little nervous about the viability of the share price.

How Is Sheung Moon Holdings' Revenue Growth Trending?

In order to justify its P/S ratio, Sheung Moon Holdings would need to produce impressive growth in excess of the industry.

Retrospectively, the last year delivered an explosive gain to the company's top line. However, this wasn't enough as the latest three year period has seen the company endure a nasty 81% drop in revenue in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

In contrast to the company, the rest of the industry is expected to grow by 13% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

In light of this, it's alarming that Sheung Moon Holdings' P/S sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

The Bottom Line On Sheung Moon Holdings' P/S

There's still some elevation in Sheung Moon Holdings' P/S, even if the same can't be said for its share price recently. While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

Our examination of Sheung Moon Holdings revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. Right now we aren't comfortable with the high P/S as this revenue performance is highly unlikely to support such positive sentiment for long. If recent medium-term revenue trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
