Jiajia Food Group Co.,Ltd (SZSE:002650) shares have continued their recent momentum with a 25% gain in the last month alone. Looking back a bit further, it's encouraging to see the stock is up 27% in the last year.

After such a large jump in price, given around half the companies in China's Food industry have price-to-sales ratios (or "P/S") below 1.9x, you may consider Jiajia Food GroupLtd as a stock to avoid entirely with its 4.6x 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 Jiajia Food GroupLtd Performed Recently?

For example, consider that Jiajia Food GroupLtd's financial performance has been poor lately as its revenue has been in decline. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. If not, then existing shareholders may be quite nervous about the viability of the share price.

What Are Revenue Growth Metrics Telling Us About The High P/S?

There's an inherent assumption that a company should far outperform the industry for P/S ratios like Jiajia Food GroupLtd's to be considered reasonable.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 22%. The last three years don't look nice either as the company has shrunk revenue by 25% 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 15% shows it's an unpleasant look.

In light of this, it's alarming that Jiajia Food GroupLtd'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. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/S falls to levels more in line with the recent negative growth rates.

The Bottom Line On Jiajia Food GroupLtd's P/S

Jiajia Food GroupLtd's P/S has grown nicely over the last month thanks to a handy boost in the share price. 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 Jiajia Food GroupLtd currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. 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. 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.
