Pentastone Electronics, Inc. (KOSDAQ:332570) shareholders have had their patience rewarded with a 32% share price jump in the last month. The annual gain comes to 146% following the latest surge, making investors sit up and take notice.
After such a large jump in price, Pentastone Electronics may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 27.3x, since almost half of all companies in Korea have P/E ratios under 13x and even P/E's lower than 7x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.
Pentastone Electronics certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. If not, then existing shareholders might be a little nervous about the viability of the share price.

The only time you'd be truly comfortable seeing a P/E as steep as Pentastone Electronics' is when the company's growth is on track to outshine the market decidedly.
Taking a look back first, we see that the company grew earnings per share by an impressive 49% last year. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.
Comparing that to the market, which is predicted to deliver 36% 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 alarming that Pentastone Electronics' 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. 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 recent growth rates.
Shares in Pentastone Electronics have built up some good momentum lately, which has really inflated its P/E. 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 Pentastone Electronics currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. Right now we are increasingly uncomfortable with the high P/E as this earnings performance isn't likely to support such positive sentiment for long. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
It's always necessary to consider the ever-present spectre of investment risk. We've identified 1 warning sign with Pentastone Electronics, and understanding should be part of your investment process.
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).
