Qinghai Huading Industrial Co., Ltd. (SHSE:600243) shareholders that were waiting for something to happen have been dealt a blow with a 27% share price drop in the last month. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 34% in that time.

Even after such a large drop in price, you could still be forgiven for thinking Qinghai Huading Industrial is a stock not worth researching with a price-to-sales ratios (or "P/S") of 3.3x, considering almost half the companies in China's Machinery industry have P/S ratios below 2.5x. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/S.

How Qinghai Huading Industrial Has Been Performing

As an illustration, revenue has deteriorated at Qinghai Huading Industrial over the last year, which is not ideal at all. One possibility is that the P/S is high because investors think the company will still do enough to outperform the broader industry in the near future. If not, then existing shareholders may be quite nervous about the viability of the share price.

Is There Enough Revenue Growth Forecasted For Qinghai Huading Industrial?

Qinghai Huading Industrial's P/S ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the industry.

Retrospectively, the last year delivered a frustrating 25% decrease to the company's top line. The last three years don't look nice either as the company has shrunk revenue by 47% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Comparing that to the industry, which is predicted to deliver 24% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

With this in mind, we find it worrying that Qinghai Huading Industrial's P/S exceeds that of its industry peers. 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.

What We Can Learn From Qinghai Huading Industrial's P/S?

Qinghai Huading Industrial's P/S remain high even after its stock plunged. 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.

We've established that Qinghai Huading Industrial currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. With a revenue decline on investors' minds, the likelihood of a souring sentiment is quite high which could send the P/S back in line with what we'd expect. Unless the the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.
