Youcare Pharmaceutical Group Co., Ltd. (SHSE:688658) shareholders would be excited to see that the share price has had a great month, posting a 26% gain and recovering from prior weakness. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 33% over that time.

After such a large jump in price, Youcare Pharmaceutical Group may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 44.2x, since almost half of all companies in China have P/E ratios under 32x and even P/E's lower than 20x are not unusual. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

For example, consider that Youcare Pharmaceutical Group's financial performance has been poor lately as its earnings have been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. If not, then existing shareholders may be quite nervous about the viability of the share price.

Is There Enough Growth For Youcare Pharmaceutical Group?

The only time you'd be truly comfortable seeing a P/E as high as Youcare Pharmaceutical Group's is when the company's growth is on track to outshine the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 52%. As a result, earnings from three years ago have also fallen 69% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

In contrast to the company, the rest of the market is expected to grow by 38% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's alarming that Youcare Pharmaceutical Group's P/E 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/E falls to levels more in line with the recent negative growth rates.

The Final Word

The large bounce in Youcare Pharmaceutical Group's shares has lifted the company's P/E to a fairly high level. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that Youcare Pharmaceutical Group currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
