Getting In Cheap On CML Microsystems plc (LON:CML) Is Unlikely

CML Microsystems plc's (LON:CML) price-to-earnings (or "P/E") ratio of 20.9x might make it look like a sell right now compared to the market in the United Kingdom, where around half of the companies have P/E ratios below 16x and even P/E's below 9x are quite common. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

While the market has experienced earnings growth lately, CML Microsystems' earnings have gone into reverse gear, which is not great. One possibility is that the P/E is high because investors think this poor earnings performance will turn the corner. If not, then existing shareholders may be extremely nervous about the viability of the share price.

Does Growth Match The High P/E?

The only time you'd be truly comfortable seeing a P/E as high as CML Microsystems' is when the company's growth is on track to outshine the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 57%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 166% 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.

Shifting to the future, estimates from the two analysts covering the company suggest earnings growth is heading into negative territory, declining 41% over the next year. That's not great when the rest of the market is expected to grow by 19%.

With this information, we find it concerning that CML Microsystems is trading at a P/E higher than the market. Apparently many investors in the company reject the analyst cohort's pessimism and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as these declining earnings are likely to weigh heavily on the share price eventually.

What We Can Learn From CML Microsystems' 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.

Our examination of CML Microsystems' analyst forecasts revealed that its outlook for shrinking earnings isn't impacting its high P/E anywhere near as much as we would have predicted. When we see a poor outlook with earnings heading backwards, we suspect the share price is at risk of declining, sending the high P/E lower. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.
