FIH Mobile Limited (HKG:2038) shares have had a horrible month, losing 27% after a relatively good period beforehand. The last month has meant the stock is now only up 9.7% during the last year.

In spite of the heavy fall in price, there still wouldn't be many who think FIH Mobile's price-to-sales (or "P/S") ratio of 0.1x is worth a mention when the median P/S in Hong Kong's Electronic industry is similar at about 0.3x. 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.

What Does FIH Mobile's Recent Performance Look Like?

For example, consider that FIH Mobile's financial performance has been poor lately as its revenue has been in decline. 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.

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

There's an inherent assumption that a company should be matching the industry for P/S ratios like FIH Mobile's to be considered reasonable.

Taking a look back first, the company's revenue growth last year wasn't something to get excited about as it posted a disappointing decline of 12%. As a result, revenue from three years ago have also fallen 34% overall. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Comparing that to the industry, which is predicted to deliver 17% 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 FIH Mobile's P/S exceeds that of its industry peers. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh on the share price eventually.

The Key Takeaway

FIH Mobile's plummeting stock price has brought its P/S back to a similar region as the rest of 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.

The fact that FIH Mobile currently trades at a P/S on par with the rest of the industry is surprising to us since its recent revenues have been in decline over the medium-term, all while the industry is set to grow. When we see revenue heading backwards in the context of growing industry forecasts, it'd make sense to expect a possible share price decline on the horizon, sending the moderate P/S lower. Unless the the circumstances surrounding the recent medium-term improve, it wouldn't be wrong to expect a a difficult period ahead for the company's shareholders.
