Unfortunately for some shareholders, the Shenzhen Success Electronics Co., Ltd (SZSE:002289) share price has dived 26% in the last thirty days, prolonging recent pain. The recent drop completes a disastrous twelve months for shareholders, who are sitting on a 53% loss during that time.

Although its price has dipped substantially, you could still be forgiven for thinking Shenzhen Success Electronics is a stock not worth researching with a price-to-sales ratios (or "P/S") of 5.1x, considering almost half the companies in China's Electronic industry have P/S ratios below 3.4x. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/S.

How Has Shenzhen Success Electronics Performed Recently?

The revenue growth achieved at Shenzhen Success Electronics over the last year would be more than acceptable for most companies. One possibility is that the P/S ratio is high because investors think this respectable revenue growth will be enough to outperform the broader industry in the near future. However, if this isn't the case, investors might get caught out paying too much for the stock.

Do Revenue Forecasts Match The High P/S Ratio?

Shenzhen Success Electronics' P/S ratio would be typical for a company that's expected to deliver solid growth, and importantly, perform better than the industry.

Retrospectively, the last year delivered an exceptional 17% gain to the company's top line. Despite this strong recent growth, it's still struggling to catch up as its three-year revenue frustratingly shrank by 3.4% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenues over that time.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 25% shows it's an unpleasant look.

In light of this, it's alarming that Shenzhen Success Electronics' P/S sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

The Key Takeaway

Shenzhen Success Electronics' P/S remain high even after its stock plunged. 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.

We've established that Shenzhen Success Electronics currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. When we see revenue heading backwards and underperforming the industry forecasts, we feel the possibility of the share price declining is very real, bringing the P/S back into the realm of reasonability. If recent medium-term revenue trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
