Shenzhen Lihexing Co.,Ltd. (SZSE:301013) shareholders are no doubt pleased to see that the share price has bounced 52% in the last month, although it is still struggling to make up recently lost ground. Longer-term shareholders would be thankful for the recovery in the share price since it's now virtually flat for the year after the recent bounce.

After such a large jump in price, when almost half of the companies in China's Electronic industry have price-to-sales ratios (or "P/S") below 3.9x, you may consider Shenzhen LihexingLtd as a stock not worth researching with its 7.3x 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 Shenzhen LihexingLtd Has Been Performing

For example, consider that Shenzhen LihexingLtd's financial performance has been pretty ordinary lately as revenue growth is non-existent. Perhaps the market believes that revenue growth will improve markedly over current levels, inflating the P/S ratio. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Revenue Growth Forecasted For Shenzhen LihexingLtd?

Shenzhen LihexingLtd'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.

If we review the last year of revenue, the company posted a result that saw barely any deviation from a year ago. The lack of growth did nothing to help the company's aggregate three-year performance, which is an unsavory 17% drop in revenue. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

In contrast to the company, the rest of the industry is expected to grow by 25% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this information, we find it concerning that Shenzhen LihexingLtd is trading at a P/S higher than the industry. 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 We Can Learn From Shenzhen LihexingLtd's P/S?

Shares in Shenzhen LihexingLtd have seen a strong upwards swing lately, which has really helped boost its P/S figure. While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

We've established that Shenzhen LihexingLtd 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. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.
