Is A High Price-to-Earnings Ratio Good?

How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. Earnings growth means that in the future the 'E' will be higher. That means unless the share price increases, the P/E will reduce in a few years. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Blue Star increased earnings per share by 6.1% last year. And earnings per share have improved by 17% annually, over the last five years.

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. Thus, the metric does not reflect cash or debt held by the company. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

Blue Star's Balance Sheet

Net debt totals just 3.9% of Blue Star's market cap. So it doesn't have as many options as it would with net cash, but its debt would not have much of an impact on its P/E ratio.

Blue Star's P/E is 38.7 which is way above average (12.9) in its market. With modest debt relative to its size, and modest earnings growth, the market is likely expecting sustained long-term growth, if not a near-term improvement.
