The Mingfa Group (International) Company Limited (HKG:846) share price has softened a substantial 30% over the previous 30 days, handing back much of the gains the stock has made lately. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 25% in that time.

Even after such a large drop in price, there still wouldn't be many who think Mingfa Group (International)'s price-to-sales (or "P/S") ratio of 0.1x is worth a mention when the median P/S in Hong Kong's Real Estate industry is similar at about 0.5x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

What Does Mingfa Group (International)'s P/S Mean For Shareholders?

As an illustration, revenue has deteriorated at Mingfa Group (International) over the last year, which is not ideal at all. Perhaps investors believe the recent revenue performance is enough to keep in line with the industry, which is keeping the P/S from dropping off. If you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

How Is Mingfa Group (International)'s Revenue Growth Trending?

There's an inherent assumption that a company should be matching the industry for P/S ratios like Mingfa Group (International)'s to be considered reasonable.

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 9.9%. This means it has also seen a slide in revenue over the longer-term as revenue is down 26% 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 4.6% 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 Mingfa Group (International) is trading at a fairly similar P/S compared to the industry. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

The Final Word

Mingfa Group (International)'s plummeting stock price has brought its P/S back to a similar region as the rest of the industry. 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.

The fact that Mingfa Group (International) currently trades at a P/S on par with the rest of the industry is surprising to us since its recent revenues have been in decline over the medium-term, all while the industry is set to grow. Even though it matches the industry, we're uncomfortable with the current P/S ratio, as this dismal revenue performance is unlikely to support a more positive sentiment for long. Unless the recent medium-term conditions improve markedly, investors will have a hard time accepting the share price as fair value.
