When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") above 18x, you may consider Silgan Holdings Inc. (NYSE:SLGN) as an attractive investment with its 15.3x P/E ratio. However, the P/E might be low for a reason and it requires further investigation to determine if it's justified.

The recently shrinking earnings for Silgan Holdings have been in line with the market. One possibility is that the P/E is low because investors think the company's earnings may begin to slide even faster. If you still like the company, you'd want its earnings trajectory to turn around before making any decisions. In saying that, existing shareholders may feel hopeful about the share price if the company's earnings continue tracking the market.

Is There Any Growth For Silgan Holdings?

Silgan Holdings' P/E ratio would be typical for a company that's only expected to deliver limited growth, and importantly, perform worse than 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 3.6%. This means it has also seen a slide in earnings over the longer-term as EPS is down 1.3% in total over the last three years. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Turning to the outlook, the next three years should generate growth of 8.9% each year as estimated by the eleven analysts watching the company. That's shaping up to be similar to the 10% each year growth forecast for the broader market.

With this information, we find it odd that Silgan Holdings is trading at a P/E lower than the market. Apparently some shareholders are doubtful of the forecasts and have been accepting lower selling prices.

The Final Word

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We've established that Silgan Holdings currently trades on a lower than expected P/E since its forecast growth is in line with the wider market. There could be some unobserved threats to earnings preventing the P/E ratio from matching the outlook. It appears some are indeed anticipating earnings instability, because these conditions should normally provide more support to the share price.
