YouYou Foods Co., Ltd. (SHSE:603697) shares have had a horrible month, losing 26% after a relatively good period beforehand. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 26% in that time.

Even after such a large drop in price, YouYou Foods may still be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 18.8x, since almost half of all companies in China have P/E ratios greater than 28x and even P/E's higher than 50x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

The earnings growth achieved at YouYou Foods over the last year would be more than acceptable for most companies. One possibility is that the P/E is low because investors think this respectable earnings growth might actually underperform the broader market in the near future. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

Does Growth Match The Low P/E?

In order to justify its P/E ratio, YouYou Foods would need to produce sluggish growth that's trailing the market.

If we review the last year of earnings growth, the company posted a worthy increase of 9.0%. Still, lamentably EPS has fallen 26% in aggregate from three years ago, which is disappointing. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 41% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's understandable that YouYou Foods' P/E would sit below the majority of other companies. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. Even just maintaining these prices could be difficult to achieve as recent earnings trends are already weighing down the shares.

The Key Takeaway

The softening of YouYou Foods' shares means its P/E is now sitting at a pretty low level. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

We've established that YouYou Foods maintains its low P/E on the weakness of its sliding earnings over the medium-term, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. If recent medium-term earnings trends continue, it's hard to see the share price moving strongly in either direction in the near future under these circumstances.
