There's Reason For Concern Over POPER Co.,Ltd.'s (TSE:5134) Massive 26% Price Jump

Despite an already strong run, POPER Co.,Ltd. (TSE:5134) shares have been powering on, with a gain of 26% in the last thirty days. Looking back a bit further, it's encouraging to see the stock is up 26% in the last year.

After such a large jump in price, POPERLtd may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 36.7x, since almost half of all companies in Japan have P/E ratios under 13x and even P/E's lower than 9x 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.

POPERLtd certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. 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?

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

Retrospectively, the last year delivered an exceptional 214% gain to the company's bottom line. Still, EPS has barely risen at all from three years ago in total, which is not ideal. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

This is in contrast to the rest of the market, which is expected to grow by 11% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's alarming that POPERLtd'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.

What We Can Learn From POPERLtd's P/E?

POPERLtd'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.

We've established that POPERLtd currently trades on a much higher than expected P/E since its recent three-year growth is lower than the wider market forecast. 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.
