Despite an already strong run, SG Group Holdings Limited (HKG:1657) shares have been powering on, with a gain of 54% in the last thirty days. Looking back a bit further, it's encouraging to see the stock is up 50% in the last year.

Even after such a large jump in price, it's still not a stretch to say that SG Group Holdings' price-to-sales (or "P/S") ratio of 1.1x right now seems quite "middle-of-the-road" compared to the Luxury industry in Hong Kong, where the median P/S ratio is around 0.6x. 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.

How Has SG Group Holdings Performed Recently?

SG Group Holdings has been doing a good job lately as it's been growing revenue at a solid pace. It might be that many expect the respectable revenue performance to wane, which has kept the P/S from rising. 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 not quite in favour.

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

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

Retrospectively, the last year delivered a decent 12% gain to the company's revenues. The solid recent performance means it was also able to grow revenue by 8.1% in total over the last three years. Therefore, it's fair to say the revenue growth recently has been respectable for the company.

Comparing that to the industry, which is predicted to deliver 12% growth in the next 12 months, the company's momentum is weaker, based on recent medium-term annualised revenue results.

In light of this, it's curious that SG Group Holdings' P/S sits in line with the majority of other companies. Apparently many investors in the company are less bearish than recent times would indicate and aren't willing to let go of their stock right now. They may be setting themselves up for future disappointment if the P/S falls to levels more in line with recent growth rates.

Our examination of SG Group Holdings revealed its poor three-year revenue trends aren't resulting in a lower P/S as per our expectations, given they look worse than current industry outlook. Right now we are uncomfortable with the P/S as this revenue performance isn't likely to support a more positive sentiment for long. If recent medium-term revenue trends continue, the probability of a share price decline will become quite substantial, placing shareholders at risk.
