How Does mBank's (WSE:MBK) P/E Compare To Its Industry, After Its Big Share Price Gain?

mBank (WSE:MBK) shareholders are no doubt pleased to see that the share price has had a great month, posting a 33% gain, recovering from prior weakness. But shareholders may not all be feeling jubilant, since the share price is still down 43% in the last year.

All else being equal, a sharp share price increase should make a stock less attractive to potential investors. While the market sentiment towards a stock is very changeable, in the long run, the share price will tend to move in the same direction as earnings per share. So some would prefer to hold off buying when there is a lot of optimism towards a stock. One way to gauge market expectations of a stock is to look at its Price to Earnings Ratio (PE Ratio). Investors have optimistic expectations of companies with higher P/E ratios, compared to companies with lower P/E ratios.

How Growth Rates Impact P/E Ratios

If earnings fall then in the future the 'E' will be lower. Therefore, even if you pay a low multiple of earnings now, that multiple will become higher in the future. Then, a higher P/E might scare off shareholders, pushing the share price down.

mBank's earnings per share fell by 12% in the last twelve months. And EPS is down 7.8% a year, over the last 5 years. This could justify a pessimistic P/E.

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

The 'Price' in P/E reflects the market capitalization of the company. 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.
