Differ Group Auto Limited (HKG:6878) shares have had a horrible month, losing 35% after a relatively good period beforehand. The recent drop completes a disastrous twelve months for shareholders, who are sitting on a 69% loss during that time.

After such a large drop in price, Differ Group Auto's price-to-sales (or "P/S") ratio of 0.2x might make it look like a buy right now compared to the Consumer Finance industry in Hong Kong, where around half of the companies have P/S ratios above 1.7x and even P/S above 4x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/S.

What Does Differ Group Auto's P/S Mean For Shareholders?

Revenue has risen firmly for Differ Group Auto recently, which is pleasing to see. One possibility is that the P/S is low because investors think this respectable revenue growth might actually underperform the broader industry in the near future. 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 Differ Group Auto's to be considered reasonable.

If we review the last year of revenue growth, the company posted a terrific increase of 18%. Still, revenue has fallen 66% in total from three years ago, which is quite disappointing. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Comparing that to the industry, which is predicted to deliver 35% 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 are not surprised that Differ Group Auto is trading at a P/S lower than the industry. 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.

The Final Word

The southerly movements of Differ Group Auto's shares means its P/S is now sitting at a pretty low level. Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Differ Group Auto 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. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises either. Given the current circumstances, it seems unlikely that the share price will experience any significant movement in either direction in the near future if recent medium-term revenue trends persist.
