Those holding Tianjin Keyvia Electric Co.,Ltd (SZSE:300407) shares would be relieved that the share price has rebounded 29% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 17% over that time.

In spite of the firm bounce in price, Tianjin Keyvia ElectricLtd's price-to-earnings (or "P/E") ratio of 17.2x might still 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 32x and even P/E's above 58x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's limited.

Recent times have been quite advantageous for Tianjin Keyvia ElectricLtd as its earnings have been rising very briskly. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. If that doesn't eventuate, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

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

Taking a look back first, we see that the company grew earnings per share by an impressive 90% last year. Pleasingly, EPS has also lifted 130% in aggregate from three years ago, thanks to the last 12 months of growth. Therefore, it's fair to say the earnings growth recently has been superb for the company.

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.

In light of this, it's understandable that Tianjin Keyvia ElectricLtd's P/E sits below the majority of other companies. It seems most investors are expecting to see the recent limited growth rates continue into the future and are only willing to pay a reduced amount for the stock.

The Key Takeaway

Tianjin Keyvia ElectricLtd's stock might have been given a solid boost, but its P/E certainly hasn't reached any great heights. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that Tianjin Keyvia ElectricLtd maintains its low P/E on the weakness of its recent three-year growth being lower than the wider market forecast, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
