While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

Looking back five years, both National Australia Bank's share price and EPS declined; the latter at a rate of 2.4% per year. This reduction in EPS is less than the 3.2% annual reduction in the share price. So it seems the market was too confident about the business, in the past.

ASX:NAB Past and Future Earnings, October 15th 2019

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for National Australia Bank the TSR over the last 5 years was 29%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

National Australia Bank's TSR for the year was broadly in line with the market average, at 19%. Most would be happy with a gain, and it helps that the year's return is actually better than the average return over five years, which was 5.2%. It is possible that management foresight will bring growth well into the future, even if the share price slows down.
