Kopin Corporation (NASDAQ:KOPN) shareholders won't be pleased to see that the share price has had a very rough month, dropping 43% and undoing the prior period's positive performance. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 49% share price drop.

After such a large drop in price, Kopin may look like a strong buying opportunity at present with its price-to-sales (or "P/S") ratio of 1.7x, considering almost half of all companies in the Semiconductor industry in the United States have P/S ratios greater than 3.8x and even P/S higher than 11x 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.

What Does Kopin's Recent Performance Look Like?

Kopin hasn't been tracking well recently as its declining revenue compares poorly to other companies, which have seen some growth in their revenues on average. The P/S ratio is probably low because investors think this poor revenue performance isn't going to get any better. So while you could say the stock is cheap, investors will be looking for improvement before they see it as good value.

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 Kopin's to be considered reasonable.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 8.0%. The last three years don't look nice either as the company has shrunk revenue by 7.7% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Shifting to the future, estimates from the four analysts covering the company suggest revenue should grow by 24% over the next year. That's shaping up to be materially lower than the 37% growth forecast for the broader industry.

With this in consideration, its clear as to why Kopin's P/S is falling short industry peers. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Final Word

Having almost fallen off a cliff, Kopin's share price has pulled its P/S way down as well. 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.

We've established that Kopin maintains its low P/S on the weakness of its forecast growth being lower than the wider industry, as expected. Shareholders' pessimism on the revenue prospects for the company seems to be the main contributor to the depressed P/S. The company will need a change of fortune to justify the P/S rising higher in the future.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 4 warning signs with Kopin (at least 2 which are potentially serious), and understanding these should be part of your investment process.
