Edan Instruments, Inc.'s (SZSE:300206) 26% Price Boost Is Out Of Tune With Earnings

Edan Instruments, Inc. (SZSE:300206) shares have had a really impressive month, gaining 26% after a shaky period beforehand. The last 30 days bring the annual gain to a very sharp 38%.

Since its price has surged higher, Edan Instruments' price-to-earnings (or "P/E") ratio of 47.8x might make it look like a sell right now compared to the market in China, where around half of the companies have P/E ratios below 36x and even P/E's below 20x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's as high as it is.

As an illustration, earnings have deteriorated at Edan Instruments over the last year, which is not ideal at all. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. If not, then existing shareholders may be quite nervous about the viability of the share price.

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

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

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 44%. This means it has also seen a slide in earnings over the longer-term as EPS is down 42% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

In contrast to the company, the rest of the market is expected to grow by 38% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's alarming that Edan Instruments' P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

The Key Takeaway

The large bounce in Edan Instruments' shares has lifted the company's P/E to a fairly high level. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

We've established that Edan Instruments currently trades on a much 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 high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
