When close to half the companies in the Chemicals industry in the United States have price-to-sales ratios (or "P/S") below 1.4x, you may consider Aspen Aerogels, Inc. (NYSE:ASPN) as a stock to avoid entirely with its 6.2x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

Do Revenue Forecasts Match The High P/S Ratio?

The only time you'd be truly comfortable seeing a P/S as steep as Aspen Aerogels' is when the company's growth is on track to outshine the industry decidedly.

If we review the last year of revenue growth, the company posted a terrific increase of 53%. The latest three year period has also seen an excellent 188% overall rise in revenue, aided by its short-term performance. Accordingly, shareholders would have definitely welcomed those medium-term rates of revenue growth.

Shifting to the future, estimates from the eight analysts covering the company suggest revenue should grow by 44% each year over the next three years. With the industry only predicted to deliver 7.0% per year, the company is positioned for a stronger revenue result.

With this in mind, it's not hard to understand why Aspen Aerogels' P/S is high relative to its industry peers. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.
