When you see that almost half of the companies in the Electronic industry in the United States have price-to-sales ratios (or "P/S") below 1.8x, Knowles Corporation (NYSE:KN) looks to be giving off some sell signals with its 2.3x P/S ratio. However, the P/S might be high for a reason and it requires further investigation to determine if it's justified.

What Does Knowles' Recent Performance Look Like?

Knowles 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. One possibility is that the P/S ratio is high because investors think this poor revenue performance will turn the corner. If not, then existing shareholders may be extremely nervous about the viability of the share price.

How Is Knowles' Revenue Growth Trending?

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

Retrospectively, the last year delivered a frustrating 14% decrease to the company's top line. The last three years don't look nice either as the company has shrunk revenue by 8.7% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Turning to the outlook, the next year should generate growth of 20% as estimated by the four analysts watching the company. Meanwhile, the rest of the industry is forecast to only expand by 6.9%, which is noticeably less attractive.

With this in mind, it's not hard to understand why Knowles' P/S is high relative to its industry peers. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

What Does Knowles' P/S Mean For Investors?

Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our look into Knowles shows that its P/S ratio remains high on the merit of its strong future revenues. At this stage investors feel the potential for a deterioration in revenues is quite remote, justifying the elevated P/S ratio. It's hard to see the share price falling strongly in the near future under these circumstances.
