To the annoyance of some shareholders, Mulsanne Group Holding Limited (HKG:1817) shares are down a considerable 35% in the last month, which continues a horrid run for the company. The recent drop completes a disastrous twelve months for shareholders, who are sitting on a 83% loss during that time.

In spite of the heavy fall in price, there still wouldn't be many who think Mulsanne Group Holding's price-to-sales (or "P/S") ratio of 0.2x is worth a mention when the median P/S in Hong Kong's Specialty Retail industry is similar at about 0.4x. While this might not raise any eyebrows, if the P/S ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

What Does Mulsanne Group Holding's Recent Performance Look Like?

For instance, Mulsanne Group Holding's receding revenue in recent times would have to be some food for thought. 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 not, then existing shareholders may be a little nervous about the viability of the share price.

Do Revenue Forecasts Match The P/S Ratio?

There's an inherent assumption that a company should be matching the industry for P/S ratios like Mulsanne Group Holding'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 6.9%. This means it has also seen a slide in revenue over the longer-term as revenue is down 24% 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 16% shows it's an unpleasant look.

In light of this, it's somewhat alarming that Mulsanne Group Holding's P/S sits in line with the majority of other companies. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. 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.

What Does Mulsanne Group Holding's P/S Mean For Investors?

Following Mulsanne Group Holding's share price tumble, its P/S is just clinging on to the industry median P/S. 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.

We find it unexpected that Mulsanne Group Holding trades at a P/S ratio that is comparable to the rest of the industry, despite experiencing declining revenues during the medium-term, while the industry as a whole is expected to grow. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
