With a price-to-earnings (or "P/E") ratio of 79.8x 3Peak Incorporated (SHSE:688536) may be sending very bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 33x and even P/E's lower than 20x 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.

3Peak certainly has been doing a good job lately as it's been growing earnings more than most other companies. It seems that many are expecting the strong earnings performance to persist, which has raised the P/E. If not, then existing shareholders might be a little nervous about the viability of the share price.

Check out our latest analysis for 3Peak

What Are Growth Metrics Telling Us About The High P/E?

The only time you'd be truly comfortable seeing a P/E as steep as 3Peak's is when the company's growth is on track to outshine the market decidedly.

Taking a look back first, we see that the company grew earnings per share by an impressive 156% last year. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Turning to the outlook, the next three years should generate growth of 26% per year as estimated by the seven analysts watching the company. That's shaping up to be similar to the 27% each year growth forecast for the broader market.

In light of this, it's curious that 3Peak's P/E sits above the majority of other companies. Apparently many investors in the company are more bullish than analysts indicate and aren't willing to let go of their stock right now. These shareholders may be setting themselves up for disappointment if the P/E falls to levels more in line with the growth outlook.

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.

Our examination of 3Peak's analyst forecasts revealed that its market-matching earnings outlook isn't impacting its high P/E as much as we would have predicted. When we see an average earnings outlook with market-like growth, we suspect the share price is at risk of declining, sending the high P/E lower. Unless these conditions improve, it's challenging to accept these prices as being reasonable.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 2 warning signs with 3Peak (at least 1 which doesn't sit too well with us), and understanding them should be part of your investment process.

Of course, you might also be able to find a better stock than 3Peak. So you may wish to see this free collection of other companies that sit on P/E's below 20x and have grown earnings strongly.
