Over the past five years, the Southwest’s stock has performed very similarly to the AMEX Airline Index, an equally weighted composite of the world’s largest companies in the airline industry. However, Southwest has dropped off in recent months, as seen in the 6 and 12 month graphs. The S&P 500 outperformed both Southwest and the Airline Composite over both 12 months and 5 years. Southwest’s recent dip is likely attributable to lower than expected earnings over 2011. Most analysts seem to agree that that the stock is undervalued and that Southwest is well-poised for growth in 2012.13
