Shanxi Antai Group Co.,Ltd (SHSE:600408) shares have continued their recent momentum with a 28% gain in the last month alone. Longer-term shareholders would be thankful for the recovery in the share price since it's now virtually flat for the year after the recent bounce.

Even after such a large jump in price, Shanxi Antai GroupLtd may still be sending bullish signals at the moment with its price-to-sales (or "P/S") ratio of 0.4x, since almost half of all companies in the Metals and Mining industry in China have P/S ratios greater than 1.5x and even P/S higher than 4x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/S.

What Does Shanxi Antai GroupLtd's P/S Mean For Shareholders?

For example, consider that Shanxi Antai GroupLtd's financial performance has been poor lately as its revenue has been in decline. Perhaps the market believes the recent revenue performance isn't good enough to keep up the industry, causing the P/S ratio to suffer. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Do Revenue Forecasts Match The Low P/S Ratio?

There's an inherent assumption that a company should underperform the industry for P/S ratios like Shanxi Antai GroupLtd's 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 29%. This means it has also seen a slide in revenue over the longer-term as revenue is down 39% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 15% shows it's an unpleasant look.

In light of this, it's understandable that Shanxi Antai GroupLtd'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. Even just maintaining these prices could be difficult to achieve as recent revenue trends are already weighing down the shares.

The Key Takeaway

The latest share price surge wasn't enough to lift Shanxi Antai GroupLtd's P/S close to the industry median. 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 Shanxi Antai GroupLtd confirms that the company's shrinking revenue over the past medium-term is a key factor in its low price-to-sales ratio, given the industry is projected to grow. At this stage investors feel the potential for an improvement in revenue isn't great enough to justify a higher P/S ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
