Franklin Wireless Corp. (NASDAQ:FKWL) shares have continued their recent momentum with a 26% gain in the last month alone. Looking further back, the 18% rise over the last twelve months isn't too bad notwithstanding the strength over the last 30 days.

Although its price has surged higher, you could still be forgiven for feeling indifferent about Franklin Wireless' P/S ratio of 1.1x, since the median price-to-sales (or "P/S") ratio for the Communications industry in the United States is also close to 1x. 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 Franklin Wireless' Recent Performance Look Like?

It looks like revenue growth has deserted Franklin Wireless recently, which is not something to boast about. One possibility is that the P/S is moderate because investors think this benign revenue growth rate might not be enough to outperform the broader industry in the near future. Those who are bullish on Franklin Wireless will be hoping that this isn't the case, so that they can pick up the stock at a lower valuation.

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

Franklin Wireless' P/S ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the industry.

If we review the last year of revenue, the company posted a result that saw barely any deviation from a year ago. This isn't what shareholders were looking for as it means they've been left with a 80% decline in revenue over the last three years in total. 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 4.7% 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 somewhat alarming that Franklin Wireless' P/S sits in line with the majority of other companies. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. There's a 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.

The Key Takeaway

Its shares have lifted substantially and now Franklin Wireless' P/S is back within range of the industry median. It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

The fact that Franklin Wireless 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. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
