Optimistic Investors Push Jeju Semiconductor Corp. (KOSDAQ:080220) Shares Up 26% But Growth Is Lacking

Despite an already strong run, Jeju Semiconductor Corp. (KOSDAQ:080220) shares have been powering on, with a gain of 26% in the last thirty days. The last 30 days bring the annual gain to a very sharp 36%.

After such a large jump in price, Jeju Semiconductor's price-to-earnings (or "P/E") ratio of 51.8x might make it look like a strong sell right now compared to the market in Korea, where around half of the companies have P/E ratios below 14x and even P/E's below 8x 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 so lofty.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

For example, consider that Jeju Semiconductor's financial performance has been poor lately as its earnings have been in decline. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. 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?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Jeju Semiconductor's to be considered reasonable.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 27%. This means it has also seen a slide in earnings over the longer-term as EPS is down 65% in total over the last three years. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

In contrast to the company, the rest of the market is expected to grow by 33% 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 Jeju Semiconductor is trading at a P/E higher than the market. 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 very 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.

The Key Takeaway

Jeju Semiconductor's P/E is flying high just like its stock has during the last month. 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.

Our examination of Jeju Semiconductor revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely 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.
