Stoneridge, Inc. (NYSE:SRI) shareholders that were waiting for something to happen have been dealt a blow with a 31% share price drop in the last month. For any long-term shareholders, the last month ends a year to forget by locking in a 77% share price decline.

Although its price has dipped substantially, there still wouldn't be many who think Stoneridge's price-to-sales (or "P/S") ratio of 0.1x is worth a mention when the median P/S in the United States' Auto Components industry is similar at about 0.5x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

What Does Stoneridge's P/S Mean For Shareholders?

Stoneridge has been struggling lately as its revenue has declined faster than most other companies. One possibility is that the P/S is moderate because investors think the company's revenue trend will eventually fall in line with most others in the industry. If you still like the company, you'd want its revenue trajectory to turn around before making any decisions. Or at the very least, you'd be hoping it doesn't keep underperforming if your plan is to pick up some stock while it's not in favour.

How Is Stoneridge's Revenue Growth Trending?

In order to justify its P/S ratio, Stoneridge would need to produce growth that's similar to the industry.

Retrospectively, the last year delivered a frustrating 6.9% decrease to the company's top line. That put a dampener on the good run it was having over the longer-term as its three-year revenue growth is still a noteworthy 18% in total. Accordingly, while they would have preferred to keep the run going, shareholders would be roughly satisfied with the medium-term rates of revenue growth.

Looking ahead now, revenue is anticipated to slump, contracting by 4.6% during the coming year according to the dual analysts following the company. Meanwhile, the broader industry is forecast to expand by 13%, which paints a poor picture.

With this information, we find it concerning that Stoneridge is trading at a fairly similar P/S compared to the industry. Apparently many investors in the company reject the analyst cohort's pessimism and aren't willing to let go of their stock right now. There's a good chance these shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the negative growth outlook.

The Key Takeaway

Stoneridge's plummeting stock price has brought its P/S back to a similar region as the rest of the industry. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

Our check of Stoneridge's analyst forecasts revealed that its outlook for shrinking revenue isn't bringing down its P/S as much as we would have predicted. With this in mind, we don't feel the current P/S is justified as declining revenues are unlikely to support a more positive sentiment for long. If we consider the revenue outlook, the P/S seems to indicate that potential investors may be paying a premium for the stock.
