ISP Holdings Limited (HKG:2340) shareholders would be excited to see that the share price has had a great month, posting a 26% 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 3.7% over the last year.

Although its price has surged higher, it's still not a stretch to say that ISP Holdings' price-to-sales (or "P/S") ratio of 0.7x right now seems quite "middle-of-the-road" compared to the Real Estate industry in Hong Kong, where the median P/S ratio is around 0.6x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

How Has ISP Holdings Performed Recently?

ISP Holdings could be doing better as its revenue has been going backwards lately while most other companies have been seeing positive revenue growth. One possibility is that the P/S ratio is moderate because investors think this poor revenue performance will turn around. However, if this isn't the case, investors might get caught out paying too much for the stock.

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

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

Retrospectively, the last year delivered a frustrating 31% decrease to the company's top line. This means it has also seen a slide in revenue over the longer-term as revenue is down 60% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Turning to the outlook, the next year should generate growth of 22,152% as estimated by the sole analyst watching the company. With the industry only predicted to deliver 3.9%, the company is positioned for a stronger revenue result.

With this information, we find it interesting that ISP Holdings is trading at a fairly similar P/S compared to the industry. It may be that most investors aren't convinced the company can achieve future growth expectations.

The Key Takeaway

ISP Holdings' stock has a lot of momentum behind it lately, which has brought its P/S level with the rest of the industry. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

We've established that ISP Holdings currently trades on a lower than expected P/S since its forecasted revenue growth is higher than the wider industry. When we see a strong revenue outlook, with growth outpacing the industry, we can only assume potential uncertainty around these figures are what might be placing slight pressure on the P/S ratio. At least the risk of a price drop looks to be subdued, but investors seem to think future revenue could see some volatility.
