What Changzhou Galaxy Century Microelectronics Co.,Ltd.'s (SHSE:688689) 29% Share Price Gain Is Not Telling You

Those holding Changzhou Galaxy Century Microelectronics Co.,Ltd. (SHSE:688689) shares would be relieved that the share price has rebounded 29% in the last thirty days, but it needs to keep going to repair the recent damage it has caused to investor portfolios. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 31% over that time.

After such a large jump in price, Changzhou Galaxy Century MicroelectronicsLtd's price-to-earnings (or "P/E") ratio of 38.1x 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 29x and even P/E's below 18x 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 Changzhou Galaxy Century MicroelectronicsLtd 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. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Changzhou Galaxy Century MicroelectronicsLtd's Growth Trending?

There's an inherent assumption that a company should outperform the market for P/E ratios like Changzhou Galaxy Century MicroelectronicsLtd's to be considered reasonable.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 26%. As a result, earnings from three years ago have also fallen 31% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 41% shows it's an unpleasant look.

In light of this, it's alarming that Changzhou Galaxy Century MicroelectronicsLtd's 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 Final Word

Changzhou Galaxy Century MicroelectronicsLtd's P/E is getting right up there since its shares have risen strongly. Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that Changzhou Galaxy Century MicroelectronicsLtd 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.
