Nanjing Inform Storage Equipment (Group) Co., Ltd. (SHSE:603066) shareholders won't be pleased to see that the share price has had a very rough month, dropping 25% and undoing the prior period's positive performance. The drop over the last 30 days has capped off a tough year for shareholders, with the share price down 20% in that time.

Following the heavy fall in price, Nanjing Inform Storage Equipment (Group) may be sending bullish signals at the moment with its price-to-earnings (or "P/E") ratio of 20.3x, since almost half of all companies in China have P/E ratios greater than 27x and even P/E's higher than 48x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's limited.

It looks like earnings growth has deserted Nanjing Inform Storage Equipment (Group) recently, which is not something to boast about. It might be that many expect the uninspiring earnings performance to worsen, which has repressed the P/E. If not, then existing shareholders may be feeling optimistic about the future direction of the share price.

Is There Any Growth For Nanjing Inform Storage Equipment (Group)?

The only time you'd be truly comfortable seeing a P/E as low as Nanjing Inform Storage Equipment (Group)'s is when the company's growth is on track to lag the market.

If we review the last year of earnings, the company posted a result that saw barely any deviation from a year ago. Still, the latest three year period has seen an excellent 67% overall rise in EPS, in spite of its uninspiring short-term performance. So we can start by confirming that the company has done a great job of growing earnings over that time.

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 Nanjing Inform Storage Equipment (Group)'s 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

Nanjing Inform Storage Equipment (Group)'s recently weak share price has pulled its P/E below most other companies. 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.
