CIG ShangHai Co., Ltd. (SHSE:603083) shareholders would be excited to see that the share price has had a great month, posting a 28% gain and recovering from prior weakness. The last month tops off a massive increase of 191% in the last year.
Following the firm bounce in price, given close to half the companies in China have price-to-earnings ratios (or "P/E's") below 25x, you may consider CIG ShangHai as a stock to avoid entirely with its 51.4x P/E ratio. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.
With earnings growth that's exceedingly strong of late, CIG ShangHai has been doing very well. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

There's an inherent assumption that a company should far outperform the market for P/E ratios like CIG ShangHai's to be considered reasonable.
If we review the last year of earnings growth, the company posted a terrific increase of 106%. Although, its longer-term performance hasn't been as strong with three-year EPS growth being relatively non-existent overall. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.
Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's noticeably less attractive on an annualised basis.
With this information, we find it concerning that CIG ShangHai is trading at a P/E higher than the market. It seems most investors are ignoring the fairly limited recent growth rates 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 Bottom Line On CIG ShangHai's P/E
Shares in CIG ShangHai have built up some good momentum lately, which has really inflated its P/E. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.
We've established that CIG ShangHai currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. Right now we are increasingly uncomfortable with the high P/E as this earnings performance isn't likely to support such positive sentiment for long. 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.
