The OKH Global Ltd. (SGX:S3N) share price has done very well over the last month, posting an excellent gain of 158%. The last 30 days bring the annual gain to a very sharp 94%.

Even after such a large jump in price, it's still not a stretch to say that OKH Global's price-to-earnings (or "P/E") ratio of 9.7x right now seems quite "middle-of-the-road" compared to the market in Singapore, where the median P/E ratio is around 12x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

OKH Global certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. The P/E is probably moderate because investors think this strong earnings growth might not be enough to outperform the broader market in the near future. If that doesn't eventuate, then existing shareholders have reason to be feeling optimistic about the future direction of the share price.

How Is OKH Global's Growth Trending?

OKH Global's P/E ratio would be typical for a company that's only expected to deliver moderate growth, and importantly, perform in line with the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 44% last year. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

In contrast to the company, the rest of the market is expected to grow by 7.6% 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 OKH Global is trading at a fairly similar P/E to the market. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh on the share price eventually.

The Bottom Line On OKH Global's P/E

OKH Global appears to be back in favour with a solid price jump getting its P/E back in line with most other companies. 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 OKH Global revealed its shrinking earnings over the medium-term aren't impacting its P/E as much as we would have predicted, given the market is set to grow. Right now we are uncomfortable with the P/E as this earnings performance is unlikely to support a more positive sentiment for long. Unless the recent medium-term conditions improve, it's challenging to accept these prices as being reasonable.
