Shenzhen Infinova Limited's (SZSE:002528) price-to-sales (or "P/S") ratio of 5.8x might make it look like a sell right now compared to the Electronic industry in China, where around half of the companies have P/S ratios below 4.3x and even P/S below 2x are quite common. However, the P/S might be high for a reason and it requires further investigation to determine if it's justified.

How Has Shenzhen Infinova Performed Recently?

For instance, Shenzhen Infinova's receding revenue in recent times would have to be some food for thought. One possibility is that the P/S is high because investors think the company will still do enough to outperform the broader industry in the near future. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Do Revenue Forecasts Match The High P/S Ratio?

In order to justify its P/S ratio, Shenzhen Infinova would need to produce impressive growth in excess of the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 26%. This means it has also seen a slide in revenue over the longer-term as revenue is down 68% in total over the last three years. 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 62% growth in the next 12 months, the company's downward momentum based on recent medium-term revenue results is a sobering picture.

In light of this, it's alarming that Shenzhen Infinova's P/S sits above the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. There's a very 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 Shenzhen Infinova's P/S Mean For Investors?

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've established that Shenzhen Infinova currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. When we see revenue heading backwards and underperforming the industry forecasts, we feel the possibility of the share price declining is very real, bringing the P/S back into the realm of reasonability. Unless the recent medium-term conditions improve markedly, investors will have a hard time accepting the share price as fair value.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with Shenzhen Infinova, and understanding should be part of your investment process.
