There's Reason For Concern Over YBM Net, Inc.'s (KOSDAQ:057030) Price

YBM Net, Inc.'s (KOSDAQ:057030) price-to-earnings (or "P/E") ratio of 20.6x 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 11x and even P/E's below 6x 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.

As an illustration, earnings have deteriorated at YBM Net over the last year, which is not ideal at all. 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 YBM Net's to be considered reasonable.

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 37%. This has soured the latest three-year period, which nevertheless managed to deliver a decent 25% overall rise in EPS. So we can start by confirming that the company has generally done a good job of growing earnings over that time, even though it had some hiccups along the way.

Comparing that to the market, which is predicted to deliver 22% 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 YBM Net's P/E sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. 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.

The Final Word

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 YBM Net revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. 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.
