It's not a stretch to say that Olam Group Limited's (SGX:VC2) price-to-earnings (or "P/E") ratio of 13.4x right now seems quite "middle-of-the-road" compared to the market in Singapore, where the median P/E ratio is around 12x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/E.

For example, consider that Olam Group's financial performance has been poor lately as its earnings have been in decline. One possibility is that the P/E is moderate because investors think the company might still do enough to be in line with the broader market in the near future. If you like the company, you'd at least be hoping this is the case so that you could potentially pick up some stock while it's not quite in favour.

Does Growth Match The P/E?

There's an inherent assumption that a company should be matching the market for P/E ratios like Olam Group's to be considered reasonable.

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 70%. This has soured the latest three-year period, which nevertheless managed to deliver a decent 23% overall rise in EPS. 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 9.6% over the next year, materially higher than the company's recent medium-term annualised growth rates.

In light of this, it's curious that Olam Group's P/E sits in line with the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are willing to pay up for exposure to the stock. Maintaining these prices will be difficult to achieve as a continuation of recent earnings trends is likely to weigh down the shares eventually.

What We Can Learn From Olam Group's P/E?

We've established that Olam Group currently trades on a higher than expected P/E since its recent three-year growth is lower than the wider market forecast. Right now we are uncomfortable with the P/E as this earnings performance isn't likely to support a more positive sentiment for long.
