Ambertech Limited's (ASX:AMO) price-to-earnings (or "P/E") ratio of 11.9x might make it look like a buy right now compared to the market in Australia, where around half of the companies have P/E ratios above 20x and even P/E's above 37x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the reduced P/E.

For instance, Ambertech's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is low because investors think the company won't do enough to avoid underperforming the broader market in the near future. However, if this doesn't eventuate then existing shareholders may be feeling optimistic about the future direction of the share price.

Is There Any Growth For Ambertech?

The only time you'd be truly comfortable seeing a P/E as low as Ambertech's is when the company's growth is on track to lag 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 31%. The last three years don't look nice either as the company has shrunk EPS by 79% in aggregate. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

In contrast to the company, the rest of the market is expected to grow by 26% over the next year, which really puts the company's recent medium-term earnings decline into perspective.

In light of this, it's understandable that Ambertech's P/E would sit below the majority of other companies. Nonetheless, there's no guarantee the P/E has reached a floor yet with earnings going in reverse. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Final Word

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.

As we suspected, our examination of Ambertech revealed its shrinking earnings over the medium-term are contributing to its low P/E, given the market is set to grow. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. If recent medium-term earnings trends continue, it's hard to see the share price moving strongly in either direction in the near future under these circumstances.
