There's Reason For Concern Over Zero One Technology Co., Ltd.'s (TWSE:3029) Massive 34% Price Jump

Despite an already strong run, Zero One Technology Co., Ltd. (TWSE:3029) shares have been powering on, with a gain of 34% in the last thirty days. The annual gain comes to 103% following the latest surge, making investors sit up and take notice.

Following the firm bounce in price, Zero One Technology may be sending bearish signals at the moment with its price-to-earnings (or "P/E") ratio of 28.4x, since almost half of all companies in Taiwan have P/E ratios under 21x and even P/E's lower than 14x 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.

The earnings growth achieved at Zero One Technology over the last year would be more than acceptable for most companies. It might be that many expect the respectable earnings performance to beat most other companies over the coming period, which has increased investors’ willingness to pay up for the stock. If not, then existing shareholders may be a little nervous about the viability of the share price.

Does Growth Match The High P/E?

In order to justify its P/E ratio, Zero One Technology would need to produce impressive growth in excess of the market.

If we review the last year of earnings growth, the company posted a terrific increase of 16%. EPS has also lifted 16% in aggregate from three years ago, mostly thanks to the last 12 months of growth. 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 24% shows it's noticeably less attractive on an annualised basis.

With this information, we find it concerning that Zero One Technology 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. 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 Zero One Technology's P/E?

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

It's always necessary to consider the ever-present spectre of investment risk. We've identified 3 warning signs with Zero One Technology, and understanding them should be part of your investment process.
