Jinhai International Group Holdings Limited (HKG:2225) shareholders have had their patience rewarded with a 50% share price jump in the last month. Looking back a bit further, it's encouraging to see the stock is up 57% in the last year.

After such a large jump in price, you could be forgiven for thinking Jinhai International Group Holdings is a stock to steer clear of with a price-to-sales ratios (or "P/S") of 40.4x, considering almost half the companies in Hong Kong's Professional Services industry have P/S ratios below 0.7x. However, the P/S might be quite high for a reason and it requires further investigation to determine if it's justified.

What Does Jinhai International Group Holdings' P/S Mean For Shareholders?

For instance, Jinhai International Group Holdings' receding revenue in recent times would have to be some food for thought. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/S from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Jinhai International Group Holdings' Revenue Growth Trending?

There's an inherent assumption that a company should far outperform the industry for P/S ratios like Jinhai International Group Holdings' to be considered reasonable.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 27%. This means it has also seen a slide in revenue over the longer-term as revenue is down 52% in total over the last three years. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

In contrast to the company, the rest of the industry is expected to grow by 9.2% 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 Jinhai International Group 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. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh heavily on the share price eventually.

The Key Takeaway

Jinhai International Group Holdings' P/S has grown nicely over the last month thanks to a handy boost in the share price. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

We've established that Jinhai International Group Holdings currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. When we see revenue heading backwards and underperforming the industry forecasts, we feel the possibility of the share price declining is very real, bringing the P/S back into the realm of reasonability. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.
