Feitian Technologies Co., Ltd. (SZSE:300386) shareholders that were waiting for something to happen have been dealt a blow with a 27% share price drop in the last month. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 25% in that time.

Even after such a large drop in price, when almost half of the companies in China's Tech industry have price-to-sales ratios (or "P/S") below 3.1x, you may still consider Feitian Technologies as a stock probably not worth researching with its 4.3x P/S ratio. However, the P/S might be high for a reason and it requires further investigation to determine if it's justified.

How Has Feitian Technologies Performed Recently?

For instance, Feitian Technologies' receding revenue in recent times would have to be some food for thought. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/S from collapsing. 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?

In order to justify its P/S ratio, Feitian Technologies would need to produce impressive growth in excess of the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 13%. The last three years don't look nice either as the company has shrunk revenue by 18% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 28% shows it's an unpleasant look.

In light of this, it's alarming that Feitian Technologies' 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.

The Final Word

Despite the recent share price weakness, Feitian Technologies' P/S remains higher than most other companies in the industry. 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 Feitian Technologies 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. Right now we aren't comfortable with the high P/S as this revenue performance is highly unlikely to support such positive sentiment for long. 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.
