Nova Eye Medical Limited (ASX:EYE) shareholders that were waiting for something to happen have been dealt a blow with a 30% share price drop in the last month. For any long-term shareholders, the last month ends a year to forget by locking in a 51% share price decline.

After such a large drop in price, Nova Eye Medical may look like a strong buying opportunity at present with its price-to-sales (or "P/S") ratio of 0.9x, considering almost half of all companies in the Medical Equipment industry in Australia have P/S ratios greater than 3.8x and even P/S higher than 9x aren't out of the ordinary. However, the P/S might be quite low for a reason and it requires further investigation to determine if it's justified.

How Nova Eye Medical Has Been Performing

With revenue growth that's superior to most other companies of late, Nova Eye Medical has been doing relatively well. One possibility is that the P/S ratio is low because investors think this strong revenue performance might be less impressive moving forward. If not, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

Do Revenue Forecasts Match The Low P/S Ratio?

There's an inherent assumption that a company should far underperform the industry for P/S ratios like Nova Eye Medical's to be considered reasonable.

Taking a look back first, we see that the company grew revenue by an impressive 39% last year. Pleasingly, revenue has also lifted 99% 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.

Looking ahead now, revenue is anticipated to climb by 34% during the coming year according to the two analysts following the company. With the industry only predicted to deliver 19%, the company is positioned for a stronger revenue result.

In light of this, it's peculiar that Nova Eye Medical's P/S sits below the majority of other companies. Apparently some shareholders are doubtful of the forecasts and have been accepting significantly lower selling prices.

The Final Word

Nova Eye Medical's P/S looks about as weak as its stock price lately. We'd say the price-to-sales ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

To us, it seems Nova Eye Medical currently trades on a significantly depressed P/S given its forecasted revenue growth is higher than the rest of its industry. There could be some major risk factors that are placing downward pressure on the P/S ratio. It appears the market could be anticipating revenue instability, because these conditions should normally provide a boost to the share price.
