There's Reason For Concern Over Perma-Fix Environmental Services, Inc.'s (NASDAQ:PESI) Massive 34% Price Jump

Despite an already strong run, Perma-Fix Environmental Services, Inc. (NASDAQ:PESI) shares have been powering on, with a gain of 34% in the last thirty days. While recent buyers may be laughing, long-term holders might not be as pleased since the recent gain only brings the stock back to where it started a year ago.

Even after such a large jump in price, it's still not a stretch to say that Perma-Fix Environmental Services' price-to-sales (or "P/S") ratio of 1.7x right now seems quite "middle-of-the-road" compared to the Commercial Services industry in the United States, where the median P/S ratio is around 1.2x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

Do Revenue Forecasts Match The P/S Ratio?

Perma-Fix Environmental Services' 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.

Taking a look back first, we see that the company grew revenue by an impressive 27% last year. However, this wasn't enough as the latest three year period has seen the company endure a nasty 15% drop in revenue in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Shifting to the future, estimates from the lone analyst covering the company suggest revenue growth is heading into negative territory, declining 3.4% over the next year. Meanwhile, the broader industry is forecast to expand by 8.5%, which paints a poor picture.

With this in consideration, we think it doesn't make sense that Perma-Fix Environmental Services' P/S is closely matching its industry peers. Apparently many investors in the company reject the analyst cohort's pessimism and aren't willing to let go of their stock right now. There's a good chance these shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the negative growth outlook.

What We Can Learn From Perma-Fix Environmental Services' P/S?

Perma-Fix Environmental Services appears to be back in favour with a solid price jump bringing its P/S back in line with other companies in 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.

While Perma-Fix Environmental Services' P/S isn't anything out of the ordinary for companies in the industry, we didn't expect it given forecasts of revenue decline. With this in mind, we don't feel the current P/S is justified as declining revenues are unlikely to support a more positive sentiment for long. If we consider the revenue outlook, the P/S seems to indicate that potential investors may be paying a premium for the stock.
