Is A High P/E Ratio Good?

A higher P/E ratio implies that investors pay a higher price for the earning power of the business. That isn't a good or a bad thing on its own, but a high P/E means that buyers have a higher opinion of the business's prospects, relative to stocks with a lower P/E.

How Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. That means even if the current P/E is high, it will reduce over time if the share price stays flat. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

It's nice to see that Align Technology grew EPS by a stonking 42% in the last year. And it has bolstered its earnings per share by 24% per year over the last five years. So we'd generally expect it to have a relatively high P/E ratio.

A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

It's important to note that the P/E ratio considers the market capitalization, not the enterprise value. That means it doesn't take debt or cash into account. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

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.

Is Debt Impacting Align Technology's P/E?

Align Technology has net cash of US$721m. That should lead to a higher P/E than if it did have debt, because its strong balance sheets gives it more options.

The Verdict On Align Technology's P/E Ratio

Align Technology has a P/E of 33.7. That's higher than the average in its market, which is 17.8. Its net cash position is the cherry on top of its superb EPS growth. To us, this is the sort of company that we would expect to carry an above average price tag (relative to earnings).
