In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During three years of share price growth, International Consolidated Airlines Group moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. As it happens, International Consolidated Airlines Group's TSR for the last 3 years was 240%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that International Consolidated Airlines Group shareholders have received a total shareholder return of 41% over one year. And that does include the dividend. That gain is better than the annual TSR over five years, which is 21%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. It's always interesting to track share price performance over the longer term. But to understand International Consolidated Airlines Group better, we need to consider many other factors.
