Sanergy Group Limited (HKG:2459) Shares May Have Slumped 27% But Getting In Cheap Is Still Unlikely

Sanergy Group Limited (HKG:2459) shareholders that were waiting for something to happen have been dealt a blow with a 27% share price drop in the last month. For any long-term shareholders, the last month ends a year to forget by locking in a 99% share price decline.

Even after such a large drop in price, you could still be forgiven for feeling indifferent about Sanergy Group's P/S ratio of 0.5x, since the median price-to-sales (or "P/S") ratio for the Electrical industry in Hong Kong is also close to 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.

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

As an illustration, revenue has deteriorated at Sanergy Group 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 not, then existing shareholders may be a little nervous about the viability of the share price.

How Is Sanergy Group's Revenue Growth Trending?

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

Retrospectively, the last year delivered a frustrating 21% decrease to the company's top line. The last three years don't look nice either as the company has shrunk revenue by 48% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 11% shows it's an unpleasant look.

With this in mind, we find it worrying that Sanergy Group's P/S exceeds that of its industry peers. 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 Sanergy Group's P/S Mean For Investors?

With its share price dropping off a cliff, the P/S for Sanergy Group looks to be in line with the rest of the Electrical industry. Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

The fact that Sanergy Group 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 the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.
