AeroVironment, Inc. (NASDAQ:AVAV) shares have had a horrible month, losing 28% after a relatively good period beforehand. Still, a bad month hasn't completely ruined the past year with the stock gaining 32%, which is great even in a bull market.

Although its price has dipped substantially, given around half the companies in the United States' Aerospace & Defense industry have price-to-sales ratios (or "P/S") below 2.3x, you may still consider AeroVironment as a stock to avoid entirely with its 6x P/S ratio. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's so lofty.

What Does AeroVironment's Recent Performance Look Like?

With revenue growth that's inferior to most other companies of late, AeroVironment has been relatively sluggish. Perhaps the market is expecting future revenue performance to undergo a reversal of fortunes, which has elevated the P/S ratio. However, if this isn't the case, investors might get caught out paying too much for the stock.

Is There Enough Revenue Growth Forecasted For AeroVironment?

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

Taking a look back first, we see that the company grew revenue by an impressive 17% last year. Pleasingly, revenue has also lifted 74% in aggregate from three years ago, thanks to the last 12 months of growth. Therefore, it's fair to say the revenue growth recently has been superb for the company.

Shifting to the future, estimates from the seven analysts covering the company suggest revenue should grow by 14% per annum over the next three years. With the industry only predicted to deliver 3.1% each year, the company is positioned for a stronger revenue result.

With this information, we can see why AeroVironment is trading at such a high P/S compared to the industry. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

What We Can Learn From AeroVironment's P/S?

AeroVironment's shares may have suffered, but its P/S remains high. While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

As we suspected, our examination of AeroVironment's analyst forecasts revealed that its superior revenue outlook is contributing to its high P/S. At this stage investors feel the potential for a deterioration in revenues is quite remote, justifying the elevated P/S ratio.
