Beijing Jiaoda Signal Technology Co., Ltd.'s (SZSE:300851) 38% Share Price Surge Not Quite Adding Up

Those holding Beijing Jiaoda Signal Technology Co., Ltd. (SZSE:300851) shares would be relieved that the share price has rebounded 38% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. But the gains over the last month weren't enough to make shareholders whole, as the share price is still down 3.9% in the last twelve months.

After such a large jump in price, Beijing Jiaoda Signal Technology may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 40.1x, since almost half of all companies in China have P/E ratios under 30x and even P/E's lower than 18x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's as high as it is.

For instance, Beijing Jiaoda Signal Technology's receding earnings in recent times would have to be some food for thought. 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.

How Is Beijing Jiaoda Signal Technology's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as high as Beijing Jiaoda Signal Technology'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 43%. This means it has also seen a slide in earnings over the longer-term as EPS is down 64% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's an unpleasant look.

In light of this, it's alarming that Beijing Jiaoda Signal Technology'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

Beijing Jiaoda Signal Technology shares have received a push in the right direction, but its P/E is elevated too. 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.

Our examination of Beijing Jiaoda Signal Technology revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. 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.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 5 warning signs with Beijing Jiaoda Signal Technology (at least 1 which is significant), and understanding them should be part of your investment process.

It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
