PlumbFast Co., Ltd. (KOSDAQ:035200) Stock Rockets 26% As Investors Are Less Pessimistic Than Expected

PlumbFast Co., Ltd. (KOSDAQ:035200) shares have continued their recent momentum with a 26% gain in the last month alone. While recent buyers may be laughing, long-term holders might not be as pleased since the recent gain only brings the stock back to where it started a year ago.

After such a large jump in price, PlumbFast may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 23.2x, since almost half of all companies in Korea have P/E ratios under 10x and even P/E's lower than 6x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

For instance, PlumbFast's receding earnings in recent times would have to be some food for thought. 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. If not, then existing shareholders may be quite nervous about the viability of the share price.

Does Growth Match The High P/E?

PlumbFast'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.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 18%. As a result, earnings from three years ago have also fallen 32% overall. 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 36% 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 PlumbFast is trading at a P/E higher than the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. 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

The strong share price surge has got PlumbFast's P/E rushing to great heights as well. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

We've established that PlumbFast currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. 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.
