Ninebot Limited's (SHSE:689009) price-to-earnings (or "P/E") ratio of 28.7x might make it look like a buy right now compared to the market in China, where around half of the companies have P/E ratios above 36x and even P/E's above 70x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

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. One possibility is that the P/E is low because investors think the company's earnings are going to fall away like everyone else's soon. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's out of favour.

How Is Ninebot's Growth Trending?

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

Retrospectively, the last year delivered an exceptional 173% gain to the company's bottom line. Pleasingly, EPS has also lifted 203% in aggregate from three years ago, thanks to the last 12 months of growth. So we can start by confirming that the company has done a great job of growing earnings over that time.

Shifting to the future, estimates from the nine analysts covering the company suggest earnings should grow by 28% over the next year. Meanwhile, the rest of the market is forecast to expand by 40%, which is noticeably more attractive.

In light of this, it's understandable that Ninebot's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

The Key Takeaway

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.

As we suspected, our examination of Ninebot's analyst forecasts revealed that its inferior earnings outlook is contributing to its low P/E. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. It's hard to see the share price rising strongly in the near future under these circumstances.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with Ninebot, and understanding should be part of your investment process.
