When close to half the companies in the Machinery industry in China have price-to-sales ratios (or "P/S") below 2.4x, you may consider Shaanxi Aerospace Power Hi-Tech Co., Ltd. (SHSE:600343) as a stock to avoid entirely with its 5.7x 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 so lofty.

How Has Shaanxi Aerospace Power Hi-Tech Performed Recently?

For instance, Shaanxi Aerospace Power Hi-Tech's receding revenue in recent times would have to be some food for thought. One possibility is that the P/S is high because investors think the company will still do 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?

Shaanxi Aerospace Power Hi-Tech's P/S ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 23%. This means it has also seen a slide in revenue over the longer-term as revenue is down 27% in total over the last three years. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenue over that time.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 22% shows it's an unpleasant look.

In light of this, it's alarming that Shaanxi Aerospace Power Hi-Tech's P/S sits above the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent revenue trends is likely to weigh heavily on the share price eventually.

What Does Shaanxi Aerospace Power Hi-Tech's P/S Mean For Investors?

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.

Our examination of Shaanxi Aerospace Power Hi-Tech revealed its shrinking revenue over the medium-term isn't resulting in a P/S as low as we expected, given the industry is set to grow. With a revenue decline on investors' minds, the likelihood of a souring sentiment is quite high which could send the P/S back in line with what we'd expect. 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.
