Fuchun Technology Co., Ltd. (SZSE:300299) shareholders would be excited to see that the share price has had a great month, posting a 27% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 33% in the last twelve months.

After such a large jump in price, when almost half of the companies in China's Entertainment industry have price-to-sales ratios (or "P/S") below 5.4x, you may consider Fuchun Technology as a stock not worth researching with its 10x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

How Fuchun Technology Has Been Performing

As an illustration, revenue has deteriorated at Fuchun Technology over the last year, which is not ideal at all. 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.

Do Revenue Forecasts Match The High P/S Ratio?

In order to justify its P/S ratio, Fuchun Technology would need to produce outstanding growth that's well in excess of the industry.

Retrospectively, the last year delivered a frustrating 25% decrease to the company's top line. This means it has also seen a slide in revenue over the longer-term as revenue is down 26% in total over the last three years. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 23% shows it's an unpleasant look.

In light of this, it's alarming that Fuchun Technology's 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 Fuchun Technology's P/S

The strong share price surge has lead to Fuchun Technology's P/S soaring as well. 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 examination of Fuchun Technology 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. 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. 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.
