Despite an already strong run, Lanzhou Huanghe Enterprise Co., Ltd (SZSE:000929) shares have been powering on, with a gain of 35% in the last thirty days. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 11% over that time.

Following the firm bounce in price, when almost half of the companies in China's Beverage industry have price-to-sales ratios (or "P/S") below 5x, you may consider Lanzhou Huanghe Enterprise as a stock probably not worth researching with its 7.4x P/S ratio. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's as high as it is.

How Has Lanzhou Huanghe Enterprise Performed Recently?

As an illustration, revenue has deteriorated at Lanzhou Huanghe Enterprise over the last year, which is not ideal at all. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. However, if this isn't the case, investors might get caught out paying too much for the stock.

Do Revenue Forecasts Match The High P/S Ratio?

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

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 11%. This means it has also seen a slide in revenue over the longer-term as revenue is down 32% in total over the last three years. 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 13% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

With this information, we find it concerning that Lanzhou Huanghe Enterprise is trading at a P/S higher than the industry. 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 Final Word

Lanzhou Huanghe Enterprise shares have taken a big step in a northerly direction, but its P/S is elevated as a result. 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 Lanzhou Huanghe Enterprise 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. 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.
