There wouldn't be many who think National Electronics Holdings Limited's (HKG:213) price-to-earnings (or "P/E") ratio of 10x is worth a mention when the median P/E in Hong Kong is similar at about 11x. 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.

We've found 21 US stocks that are forecast to pay a dividend yield of over 6% next year. See the full list for free.

For instance, National Electronics Holdings' receding earnings in recent times would have to be some food for thought. 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.

Is There Some Growth For National Electronics Holdings?

The only time you'd be comfortable seeing a P/E like National Electronics Holdings' 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 11%. This means it has also seen a slide in earnings over the longer-term as EPS is down 56% in total over the last three years. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

In contrast to the company, the rest of the market is expected to grow by 18% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

With this information, we find it concerning that National Electronics Holdings is trading at a fairly similar P/E to the market. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. There's a good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

What We Can Learn From National Electronics Holdings' P/E?

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that National Electronics Holdings currently trades on a higher than expected P/E since its recent earnings have been in decline over the medium-term. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the moderate P/E lower. If recent medium-term earnings trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
