Chengtun Mining Group Co., Ltd. (SHSE:600711) shareholders won't be pleased to see that the share price has had a very rough month, dropping 30% and undoing the prior period's positive performance. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 23% share price drop.

Following the heavy fall in price, given about half the companies operating in China's Metals and Mining industry have price-to-sales ratios (or "P/S") above 1.3x, you may consider Chengtun Mining Group as an attractive investment with its 0.5x 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 limited.

How Chengtun Mining Group Has Been Performing

For example, consider that Chengtun Mining Group's financial performance has been poor lately as its revenue has been in decline. One possibility is that the P/S is low because investors think the company won't do enough to avoid underperforming the broader industry in the near future. Those who are bullish on Chengtun Mining Group will be hoping that this isn't the case so that they can pick up the stock at a lower valuation.

Is There Any Revenue Growth Forecasted For Chengtun Mining Group?

Chengtun Mining Group's P/S ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse 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 5.1%. This means it has also seen a slide in revenue over the longer-term as revenue is down 42% in total over the last three years. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Comparing that to the industry, which is predicted to deliver 15% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

In light of this, it's understandable that Chengtun Mining Group's P/S would sit below the majority of other companies. Nonetheless, there's no guarantee the P/S has reached a floor yet with revenue going in reverse. There's potential for the P/S to fall to even lower levels if the company doesn't improve its top-line growth.

Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
