The past five years for Southwest Airlines (NYSE:LUV) investors has not been profitable

Southwest Airlines Co. (NYSE:LUV) shareholders should be happy to see the share price up 12% in the last quarter. But over the last half decade, the stock has not performed well. You would have done a lot better buying an index fund, since the stock has dropped 38% in that half decade.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

In the last half decade Southwest Airlines saw its share price fall as its EPS declined below zero. The recent extraordinary items contributed to this situation. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. However, we can say we'd expect to see a falling share price in this scenario.

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Southwest Airlines the TSR over the last 5 years was -35%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Southwest Airlines shareholders are up 15% for the year (even including dividends). Unfortunately this falls short of the market return. But at least that's still a gain! Over five years the TSR has been a reduction of 6% per year, over five years. It could well be that the business is stabilizing. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
