With a price-to-sales (or "P/S") ratio of 2.3x Diodes Incorporated (NASDAQ:DIOD) may be sending bullish signals at the moment, given that almost half of all the Semiconductor companies in the United States have P/S ratios greater than 4x and even P/S higher than 10x are not unusual. However, the P/S might be low for a reason and it requires further investigation to determine if it's justified.

What Does Diodes' P/S Mean For Shareholders?

Diodes could be doing better as its revenue has been going backwards lately while most other companies have been seeing positive revenue growth. The P/S ratio is probably low because investors think this poor revenue performance isn't going to get any better. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

How Is Diodes' Revenue Growth Trending?

Diodes' P/S ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 29%. This means it has also seen a slide in revenue over the longer-term as revenue is down 23% in total over the last three years. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Shifting to the future, estimates from the four analysts covering the company suggest revenue should grow by 9.9% over the next year. That's shaping up to be materially lower than the 40% growth forecast for the broader industry.

With this in consideration, its clear as to why Diodes' 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 Bottom Line On Diodes' P/S

Using the price-to-sales ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

As expected, our analysis of Diodes' analyst forecasts confirms that the company's underwhelming revenue outlook is a major contributor to its low P/S. Right now shareholders are accepting the low P/S as they concede future revenue probably won't provide any pleasant surprises. The company will need a change of fortune to justify the P/S rising higher in the future.
