Polar Power, Inc. (NASDAQ:POLA) Surges 33% Yet Its Low P/S Is No Reason For Excitement

Despite an already strong run, Polar Power, Inc. (NASDAQ:POLA) shares have been powering on, with a gain of 33% in the last thirty days. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 50% over that time.

Although its price has surged higher, Polar Power may still be sending bullish signals at the moment with its price-to-sales (or "P/S") ratio of 0.8x, since almost half of all companies in the Electrical industry in the United States have P/S ratios greater than 1.8x and even P/S higher than 5x are not unusual. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's limited.

What Does Polar Power's P/S Mean For Shareholders?

As an illustration, revenue has deteriorated at Polar Power over the last year, which is not ideal at all. One possibility is that the P/S is low because investors think the company won't do enough to avoid underperforming the broader industry in the near future. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Do Revenue Forecasts Match The Low P/S Ratio?

The only time you'd be truly comfortable seeing a P/S as low as Polar Power's is when the company's growth is on track to lag the industry.

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 33%. The last three years don't look nice either as the company has shrunk revenue by 9.3% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 12% shows it's an unpleasant look.

In light of this, it's understandable that Polar Power's P/S would sit below the majority of other companies. Nonetheless, there's no guarantee the P/S has reached a floor yet with revenue going in reverse. There's potential for the P/S to fall to even lower levels if the company doesn't improve its top-line growth.

The Key Takeaway

The latest share price surge wasn't enough to lift Polar Power's P/S close to the industry median. 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.

As we suspected, our examination of Polar Power revealed its shrinking revenue over the medium-term is contributing to its low P/S, given the industry is set to grow. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises either. Given the current circumstances, it seems unlikely that the share price will experience any significant movement in either direction in the near future if recent medium-term revenue trends persist.
