Golden Power Group Holdings Limited (HKG:3919) shareholders would be excited to see that the share price has had a great month, posting a 48% gain and recovering from prior weakness. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 22% in the last twelve months.

Although its price has surged higher, you could still be forgiven for feeling indifferent about Golden Power Group Holdings' P/S ratio of 0.1x, since the median price-to-sales (or "P/S") ratio for the Electrical industry in Hong Kong is also close to 0.5x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

How Has Golden Power Group Holdings Performed Recently?

Revenue has risen at a steady rate over the last year for Golden Power Group Holdings, which is generally not a bad outcome. One possibility is that the P/S is moderate because investors think this good revenue growth might only be parallel to the broader industry in the near future. 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.

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 Golden Power Group Holdings' to be considered reasonable.

Retrospectively, the last year delivered a decent 4.8% gain to the company's revenues. However, this wasn't enough as the latest three year period has seen an unpleasant 12% overall drop in revenue. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Comparing that to the industry, which is predicted to deliver 27% 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 Golden Power Group Holdings' 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.

The Bottom Line On Golden Power Group Holdings' P/S

Golden Power Group Holdings appears to be back in favour with a solid price jump bringing its P/S back in line with other companies in 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.

We find it unexpected that Golden Power Group 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. 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. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
