With a price-to-earnings (or "P/E") ratio of 11x Jiaze Renewables Corporation Limited (SHSE:601619) may be sending very bullish signals at the moment, given that almost half of all companies in China have P/E ratios greater than 36x and even P/E's higher than 72x are not unusual. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

For example, consider that Jiaze Renewables' financial performance has been poor lately as its earnings have been in decline. It might be that many expect the disappointing earnings performance to continue or accelerate, which has repressed the P/E. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

In order to justify its P/E ratio, Jiaze Renewables would need to produce anemic growth that's substantially trailing the market.

Retrospectively, the last year delivered a frustrating 12% decrease to the company's bottom line. However, a few very strong years before that means that it was still able to grow EPS by an impressive 43% in total over the last three years. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been more than adequate for the company.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 40% shows it's noticeably less attractive on an annualised basis.

In light of this, it's understandable that Jiaze Renewables' P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on to something they believe will continue to trail the bourse.

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.
