Shenzhen Keanda Electronic Technology Corp., Ltd. (SZSE:002972) shareholders won't be pleased to see that the share price has had a very rough month, dropping 26% 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 32% in that time.

Although its price has dipped substantially, it's still not a stretch to say that Shenzhen Keanda Electronic Technology's price-to-earnings (or "P/E") ratio of 32.1x right now seems quite "middle-of-the-road" compared to the market in China, where the median P/E ratio is around 30x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/E.

For instance, Shenzhen Keanda Electronic Technology's receding earnings in recent times would have to be some food for thought. It might be that many expect the company to put the disappointing earnings performance behind them over the coming period, which has kept the P/E from falling. If you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

Is There Some Growth For Shenzhen Keanda Electronic Technology?

The only time you'd be comfortable seeing a P/E like Shenzhen Keanda Electronic Technology's is when the company's growth is tracking the market closely.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 50%. This means it has also seen a slide in earnings over the longer-term as EPS is down 45% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 42% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

In light of this, it's somewhat alarming that Shenzhen Keanda Electronic Technology's P/E sits in line with the majority of other companies. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh on the share price eventually.

The Final Word

Shenzhen Keanda Electronic Technology's plummeting stock price has brought its P/E right back to the rest of the market. 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 Shenzhen Keanda Electronic Technology currently trades on a higher than expected P/E since its recent earnings have been in decline over the medium-term. Right now we are uncomfortable with the P/E as this earnings performance is unlikely to support a more positive sentiment for long. If recent medium-term earnings trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
