Soliton Systems K.K. (TSE:3040) Stock Rockets 25% As Investors Are Less Pessimistic Than Expected

Simply Wall St

Despite an already strong run, Soliton Systems K.K. (TSE:3040) shares have been powering on, with a gain of 25% in the last thirty days. Looking back a bit further, it's encouraging to see the stock is up 45% in the last year.

Following the firm bounce in price, given around half the companies in Japan have price-to-earnings ratios (or "P/E's") below 14x, you may consider Soliton Systems K.K as a stock to potentially avoid with its 20.1x P/E ratio. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

For example, consider that Soliton Systems K.K's financial performance has been poor lately as its earnings have been in decline. One possibility is that the P/E is high because investors think the company will still do 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.

Does Growth Match The High P/E?

In order to justify its P/E ratio, Soliton Systems K.K would need to produce impressive growth in excess of the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 4.2%. Regardless, EPS has managed to lift by a handy 9.7% in aggregate from three years ago, thanks to the earlier period of growth. Accordingly, while they would have preferred to keep the run going, shareholders would be roughly satisfied with the medium-term rates of earnings growth.

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 Soliton Systems K.K'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 Soliton Systems K.K's P/E

Soliton Systems K.K shares have received a push in the right direction, but its P/E is elevated too. We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

Our examination of Soliton Systems K.K 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.
