The formula for P/E is:

Price to Earnings Ratio = Share Price (in reporting currency) ÷ Earnings per Share (EPS)

### Is A High Price-to-Earnings Ratio Good?

The higher the P/E ratio, the higher the price tag of a business, relative to its trailing earnings. All else being equal, it’s better to pay a low price — but as Warren Buffett said, ‘It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price’.

### How Does Bank of China’s P/E Ratio Compare To Its Peers?

### How Growth Rates Impact P/E Ratios

Generally speaking the rate of earnings growth has a profound impact on a company’s P/E multiple. Earnings growth means that in the future the ‘E’ will be higher. And in that case, the P/E ratio itself will drop rather quickly. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

Bank of China saw earnings per share improve by -2.7% last year. And it has improved its earnings per share by 2.0% per year over the last three years.

### Don’t Forget: The P/E Does Not Account For Debt or Bank Deposits

The ‘Price’ in P/E reflects the market capitalization of the company. Thus, the metric does not reflect cash or debt held by the company. 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.

### Bank of China’s Balance Sheet

Bank of China has net cash of CN¥120b. This is fairly high at 12% of its market capitalization. That might mean balance sheet strength is important to the business, but should also help push the P/E a bit higher than it would otherwise be.

Bank of China trades on a P/E ratio of 4.5, which is below the HK market average of 9.6. EPS was up modestly better over the last twelve months. Also positive, the relatively strong balance sheet will allow for investment in growth. In contrast, the P/E indicates shareholders doubt that will happen!
