Vicon Holdings Limited (HKG:3878) shareholders would be excited to see that the share price has had a great month, posting a 30% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 34% in the last twelve months.

In spite of the firm bounce in price, you could still be forgiven for feeling indifferent about Vicon Holdings' P/S ratio of 0.1x, since the median price-to-sales (or "P/S") ratio for the Construction industry in Hong Kong is also close to 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 Vicon Holdings' Recent Performance Look Like?

Recent times have been quite advantageous for Vicon Holdings as its revenue has been rising very briskly. It might be that many expect the strong revenue performance to wane, which has kept the share price, and thus the P/S ratio, from rising. Those who are bullish on Vicon Holdings will be hoping that this isn't the case, so that they can pick up the stock at a lower valuation.

What Are Revenue Growth Metrics Telling Us About The P/S?

In order to justify its P/S ratio, Vicon Holdings would need to produce growth that's similar to the industry.

If we review the last year of revenue growth, the company posted a terrific increase of 166%. However, this wasn't enough as the latest three year period has seen the company endure a nasty 11% drop in revenue in aggregate. 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.

With this in mind, we find it worrying that Vicon Holdings' P/S exceeds that of its industry peers. 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 Bottom Line On Vicon Holdings' P/S

Its shares have lifted substantially and now Vicon Holdings' P/S is back within range of the industry median. It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We find it unexpected that Vicon Holdings 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.
