What Gyeongnam Steel Co., Ltd's (KOSDAQ:039240) 32% Share Price Gain Is Not Telling You

Gyeongnam Steel Co., Ltd (KOSDAQ:039240) shares have had a really impressive month, gaining 32% after a shaky period beforehand. Looking back a bit further, it's encouraging to see the stock is up 79% in the last year.

Following the firm bounce in price, given close to half the companies in Korea have price-to-earnings ratios (or "P/E's") below 11x, you may consider Gyeongnam Steel as a stock to avoid entirely with its 22.6x P/E ratio. 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.

For example, consider that Gyeongnam Steel's financial performance has been poor lately as its earnings have been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. 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?

Gyeongnam Steel's P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Retrospectively, the last year delivered a frustrating 13% decrease to the company's bottom line. That put a dampener on the good run it was having over the longer-term as its three-year EPS growth is still a noteworthy 13% in total. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been mostly respectable for the company.

This is in contrast to the rest of the market, which is expected to grow by 22% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's alarming that Gyeongnam Steel's 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. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

The Bottom Line On Gyeongnam Steel's P/E

Gyeongnam Steel's P/E is flying high just like its stock has during the last month. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

Our examination of Gyeongnam Steel 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. 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.
