Detection Technology Oyj's P/E tells us that market participants think the company will perform better than its industry peers, going forward. Clearly the market expects growth, but it isn't guaranteed. So further research is always essential. I often monitor director buying and selling.

How Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. Earnings growth means that in the future the 'E' will be higher. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Detection Technology Oyj's earnings per share fell by 5.5% in the last twelve months. But over the longer term (5 years) earnings per share have increased by 30%.

Remember: P/E Ratios Don't Consider The Balance Sheet

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. So it won't reflect the advantage of cash, or disadvantage of debt. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.
