Why We're Not Concerned Yet About Applied Optoelectronics, Inc.'s (NASDAQ:AAOI) 26% Share Price Plunge

Unfortunately for some shareholders, the Applied Optoelectronics, Inc. (NASDAQ:AAOI) share price has dived 26% in the last thirty days, prolonging recent pain. Regardless, last month's decline is barely a blip on the stock's price chart as it has gained a monstrous 462% in the last year.

Although its price has dipped substantially, when almost half of the companies in the United States' Communications industry have price-to-sales ratios (or "P/S") below 1.1x, you may still consider Applied Optoelectronics as a stock probably not worth researching with its 1.8x 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 as high as it is.

How Has Applied Optoelectronics Performed Recently?

Applied Optoelectronics could be doing better as its revenue has been going backwards lately while most other companies have been seeing positive revenue growth. It might be that many expect the dour revenue performance to recover substantially, which has kept the P/S from collapsing. However, if this isn't the case, investors might get caught out paying too much for the stock.

How Is Applied Optoelectronics' Revenue Growth Trending?

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

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 2.3%. As a result, revenue from three years ago have also fallen 7.2% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Turning to the outlook, the next year should generate growth of 32% as estimated by the four analysts watching the company. That's shaping up to be materially higher than the 1.7% growth forecast for the broader industry.

With this in mind, it's not hard to understand why Applied Optoelectronics' 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.

What We Can Learn From Applied Optoelectronics' P/S?

Applied Optoelectronics' P/S remain high even after its stock plunged. 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 Applied Optoelectronics maintains its high P/S on the strength of its forecasted revenue growth being higher than the the rest of the Communications industry, as expected. It appears that shareholders are confident in the company's future revenues, which is propping up the P/S. Unless these conditions change, they will continue to provide strong support to the share price.
