What Shinyoungwacoal,Inc.'s (KRX:005800) 25% Share Price Gain Is Not Telling You

Simply Wall St · 1d ago

The Shinyoungwacoal,Inc. (KRX:005800) share price has done very well over the last month, posting an excellent gain of 25%. The last 30 days bring the annual gain to a very sharp 90%.

After such a large jump in price, ShinyoungwacoalInc may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 18.8x, 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 as high as it is.

ShinyoungwacoalInc certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. It seems that many are expecting the strong earnings performance to beat most other companies over the coming period, which has increased investors’ willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Growth Metrics Telling Us About The High P/E?

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

Retrospectively, the last year delivered an exceptional 210% gain to the company's bottom line. As a result, it also grew EPS by 5.5% in total over the last three years. Accordingly, shareholders would have probably been satisfied with the medium-term rates of earnings growth.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 39% shows it's noticeably less attractive on an annualised basis.

With this information, we find it concerning that ShinyoungwacoalInc 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 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 Key Takeaway

The large bounce in ShinyoungwacoalInc's shares has lifted the company's P/E to a fairly high level. 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 ShinyoungwacoalInc 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. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
