With a price-to-earnings (or "P/E") ratio of 48.8x Ninebot Limited (SHSE:689009) may be sending bearish signals at the moment, given that almost half of all companies in China have P/E ratios under 35x 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.

Ninebot certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. It seems that many are expecting the company to continue defying the broader market adversity, which has increased investors' willingness to pay up for the stock. If not, then existing shareholders might be a little nervous about the viability of the share price.

How Is Ninebot's Growth Trending?

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

Retrospectively, the last year delivered a decent 4.9% gain to the company's bottom line. Although, the latest three year period in total hasn't been as good as it didn't manage to provide any growth at all. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Turning to the outlook, the next year should generate growth of 69% as estimated by the eight analysts watching the company. That's shaping up to be materially higher than the 43% growth forecast for the broader market.

With this information, we can see why Ninebot is trading at such a high P/E compared to the market. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

The Final Word

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.

We've established that Ninebot maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected. At this stage investors feel the potential for a deterioration in earnings isn't great enough to justify a lower P/E ratio. Unless these conditions change, they will continue to provide strong support to the share price.

And what about other risks? Every company has them, and we've spotted 1 warning sign for Ninebot you should know about.

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).
