GRP Limited (SGX:BLU) shares have continued their recent momentum with a 38% gain in the last month alone. Unfortunately, despite the strong performance over the last month, the full year gain of 8.1% isn't as attractive.

Even after such a large jump in price, it's still not a stretch to say that GRP's price-to-sales (or "P/S") ratio of 0.8x right now seems quite "middle-of-the-road" compared to the Electronic industry in Singapore, where the median P/S ratio is around 0.7x. 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 GRP Has Been Performing

For instance, GRP's receding revenue in recent times would have to be some food for thought. One possibility is that the P/S is moderate because investors think the company might still do enough to be in line with the broader industry in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

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

The only time you'd be comfortable seeing a P/S like GRP's is when the company's growth is tracking the industry closely.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 13%. Regardless, revenue has managed to lift by a handy 25% in aggregate from three years ago, thanks to the earlier period of growth. So we can start by confirming that the company has generally done a good job of growing revenue over that time, even though it had some hiccups along the way.

This is in contrast to the rest of the industry, which is expected to grow by 20% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's curious that GRP'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. They may be setting themselves up for future disappointment if the P/S falls to levels more in line with recent growth rates.

What We Can Learn From GRP's P/S?

GRP's stock has a lot of momentum behind it lately, which has brought its P/S level with the rest of the 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.

Our examination of GRP 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. Unless the recent medium-term conditions improve, it's hard to accept the current share price as fair value.
