There's Reason For Concern Over Shanghai Join Buy Co.,Ltd.'s (SHSE:600838) Price

With a price-to-earnings (or "P/E") ratio of 75.2x Shanghai Join Buy Co.,Ltd. (SHSE:600838) may be sending very bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 32x and even P/E's lower than 19x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

For example, consider that Shanghai Join BuyLtd'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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

The only time you'd be truly comfortable seeing a P/E as steep as Shanghai Join BuyLtd's is when the company's growth is on track to outshine the market decidedly.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 33%. The last three years don't look nice either as the company has shrunk EPS by 54% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Comparing that to the market, which is predicted to deliver 38% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we find it concerning that Shanghai Join BuyLtd is trading at a P/E higher than the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

The Key Takeaway

Using the price-to-earnings 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.

We've established that Shanghai Join BuyLtd 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.
