ECI Technology Holdings Limited (HKG:8013) shareholders that were waiting for something to happen have been dealt a blow with a 26% share price drop in the last month. The recent drop has obliterated the annual return, with the share price now down 7.4% over that longer period.

Even after such a large drop in price, it's still not a stretch to say that ECI Technology Holdings' price-to-earnings (or "P/E") ratio of 7.1x right now seems quite "middle-of-the-road" compared to the market in Hong Kong, where the median P/E ratio is around 9x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

As an illustration, earnings have deteriorated at ECI Technology Holdings over the last year, which is not ideal at all. One possibility is that the P/E is moderate because investors think the company might still do enough to be in line with the broader market in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

What Are Growth Metrics Telling Us About The P/E?

There's an inherent assumption that a company should be matching the market for P/E ratios like ECI Technology Holdings' to be considered reasonable.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 11%. Still, the latest three year period has seen an excellent 54% overall rise in EPS, in spite of its unsatisfying short-term performance. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 23% growth in the next 12 months, the company's momentum is weaker based on recent medium-term annualised earnings results.

In light of this, it's curious that ECI Technology Holdings' P/E sits in line with the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are willing to pay up for exposure to the stock. Maintaining these prices will be difficult to achieve as a continuation of recent earnings trends is likely to weigh down the shares eventually.

The Key Takeaway

ECI Technology Holdings' 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 ECI Technology Holdings currently trades on a higher than expected P/E since its recent three-year growth is lower than the wider market forecast. Right now we are uncomfortable with the P/E as this earnings performance isn't likely to support a more positive sentiment for long. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.

And what about other risks? Every company has them, and we've spotted 4 warning signs for ECI Technology Holdings (of which 2 can't be ignored!) you should know about.

It's important to make sure you look for a great company, not just the first idea you come across. So take a peek at this free list of interesting companies with strong recent earnings growth (and a low P/E).
