Wuhan Ligong Guangke Co., Ltd.'s (SZSE:300557) 35% Share Price Surge Not Quite Adding Up

Wuhan Ligong Guangke Co., Ltd. (SZSE:300557) shareholders have had their patience rewarded with a 35% share price jump in the last month. The last 30 days bring the annual gain to a very sharp 99%.

Following the firm bounce in price, Wuhan Ligong Guangke may be sending sell signals at present with a price-to-sales (or "P/S") ratio of 6x, when you consider almost half of the companies in the Electronic industry in China have P/S ratios under 4.4x and even P/S lower than 2x aren't out of the ordinary. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's as high as it is.

What Does Wuhan Ligong Guangke's Recent Performance Look Like?

Wuhan Ligong Guangke has been doing a decent job lately as it's been growing revenue at a reasonable pace. Perhaps the market believes the recent revenue performance is strong enough to outperform the industry, which has inflated the P/S ratio. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Do Revenue Forecasts Match The High P/S Ratio?

There's an inherent assumption that a company should outperform the industry for P/S ratios like Wuhan Ligong Guangke's to be considered reasonable.

Retrospectively, the last year delivered a decent 4.3% gain to the company's revenues. The solid recent performance means it was also able to grow revenue by 7.3% in total over the last three years. Therefore, it's fair to say the revenue growth recently has been respectable for the company.

This is in contrast to the rest of the industry, which is expected to grow by 25% over the next year, materially higher than the company's recent medium-term annualised growth rates.

With this information, we find it concerning that Wuhan Ligong Guangke is trading at a P/S higher than the industry. 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. 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 Wuhan Ligong Guangke's P/S?

Wuhan Ligong Guangke's P/S is on the rise since its shares have risen strongly. 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 Wuhan Ligong Guangke revealed its poor three-year revenue trends aren't detracting from the P/S as much as we though, given they look worse than current industry expectations. When we see slower than industry revenue growth but an elevated P/S, there's considerable risk of the share price declining, sending the P/S lower. Unless there is a significant improvement in the company's medium-term performance, it will be difficult to prevent the P/S ratio from declining to a more reasonable level.
