China Apex Group Limited (HKG:2011) shares have continued their recent momentum with a 39% gain in the last month alone. The last 30 days bring the annual gain to a very sharp 48%.

Following the firm bounce in price, when almost half of the companies in Hong Kong's Luxury industry have price-to-sales ratios (or "P/S") below 0.6x, you may consider China Apex Group as a stock not worth researching with its 4.4x P/S ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/S.

What Does China Apex Group's Recent Performance Look Like?

As an illustration, revenue has deteriorated at China Apex Group over the last year, which is not ideal at all. 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. If not, then existing shareholders may be quite nervous about the viability of the share price.

How Is China Apex Group's Revenue Growth Trending?

China Apex Group'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 15%. This has soured the latest three-year period, which nevertheless managed to deliver a decent 27% overall rise in revenue. Although it's been a bumpy ride, it's still fair to say the revenue growth recently has been mostly respectable for the company.

Comparing that to the industry, which is predicted to deliver 12% growth in the next 12 months, the company's momentum is weaker, based on recent medium-term annualised revenue results.

With this in mind, we find it worrying that China Apex Group's P/S exceeds that of its industry peers. 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.

The Final Word

The strong share price surge has lead to China Apex Group's P/S soaring as well. Generally, our preference is to limit the use of the price-to-sales ratio to establishing what the market thinks about the overall health of a company.

The fact that China Apex Group currently trades on a higher P/S relative to the industry is an oddity, since its recent three-year growth is lower than the wider industry forecast. Right now we aren't comfortable with the high P/S as this revenue performance isn't likely to support such positive sentiment for long. 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.
