Nihon Seiko Co., Ltd. (TSE:5729) Stock Rockets 26% But Many Are Still Ignoring The Company

Simply Wall St

Despite an already strong run, Nihon Seiko Co., Ltd. (TSE:5729) shares have been powering on, with a gain of 26% in the last thirty days. The last month tops off a massive increase of 300% in the last year.

Even after such a large jump in price, given about half the companies in Japan have price-to-earnings ratios (or "P/E's") above 15x, you may still consider Nihon Seiko as a highly attractive investment with its 7.4x 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 limited.

Nihon Seiko certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. One possibility is that the P/E is low because investors think this strong earnings growth might actually underperform the broader market in the near future. If that doesn't eventuate, then existing shareholders have reason to be quite optimistic about the future direction of the share price.

How Is Nihon Seiko's Growth Trending?

There's an inherent assumption that a company should far underperform the market for P/E ratios like Nihon Seiko's to be considered reasonable.

Retrospectively, the last year delivered an exceptional 451% gain to the company's bottom line. Pleasingly, EPS has also lifted 204% in aggregate from three years ago, thanks to the last 12 months of growth. Therefore, it's fair to say the earnings growth recently has been superb for the company.

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

In light of this, it's peculiar that Nihon Seiko's P/E sits below the majority of other companies. Apparently some shareholders believe the recent performance has exceeded its limits and have been accepting significantly lower selling prices.

What We Can Learn From Nihon Seiko's P/E?

Even after such a strong price move, Nihon Seiko's P/E still trails the rest of the market significantly. 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 Nihon Seiko revealed its three-year earnings trends aren't contributing to its P/E anywhere near as much as we would have predicted, given they look better than current market expectations. When we see strong earnings with faster-than-market growth, we assume potential risks are what might be placing significant pressure on the P/E ratio. At least price risks look to be very low if recent medium-term earnings trends continue, but investors seem to think future earnings could see a lot of volatility.
