VibroPower Corporation Limited (SGX:BJD) shareholders would be excited to see that the share price has had a great month, posting a 34% gain and recovering from prior weakness. The bad news is that even after the stocks recovery in the last 30 days, shareholders are still underwater by about 3.8% over the last year.

Although its price has surged higher, it's still not a stretch to say that VibroPower's price-to-sales (or "P/S") ratio of 0.3x right now seems quite "middle-of-the-road" compared to the Electrical industry in Singapore, seeing as it matches the P/S ratio of the wider industry. Although, it's not wise to simply ignore the P/S without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

How Has VibroPower Performed Recently?

As an illustration, revenue has deteriorated at VibroPower 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 you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

How Is VibroPower's Revenue Growth Trending?

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

Retrospectively, the last year delivered a frustrating 7.2% decrease to the company's top line. At least revenue has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. Therefore, it's fair to say that revenue growth has been inconsistent recently for the company.

This is in contrast to the rest of the industry, which is expected to grow by 38% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's curious that VibroPower's 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. Maintaining these prices will be difficult to achieve as a continuation of recent revenue trends is likely to weigh down the shares eventually.

The Bottom Line On VibroPower's P/S

Its shares have lifted substantially and now VibroPower's P/S is back within range of the industry median. 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.

Our examination of VibroPower 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.
