What WSI Co., Ltd.'s (KOSDAQ:299170) 28% Share Price Gain Is Not Telling You

The WSI Co., Ltd. (KOSDAQ:299170) share price has done very well over the last month, posting an excellent gain of 28%. Unfortunately, despite the strong performance over the last month, the full year gain of 5.6% isn't as attractive.

Following the firm bounce in price, WSI may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 46.2x, since almost half of all companies in Korea have P/E ratios under 11x and even P/E's lower than 6x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

We've discovered 3 warning signs about WSI. View them for free.

For example, consider that WSI'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.

Does Growth Match The High P/E?

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

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 54%. This means it has also seen a slide in earnings over the longer-term as EPS is down 82% 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 19% 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 WSI 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 Bottom Line On WSI's P/E

WSI's P/E is flying high just like its stock has during the last month. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of WSI 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. 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.
