Southwest Airlines (LUV) Could Be 11% Undervalued On Its Cash Flow Reset

Simply Wall St · 1d ago

Southwest Airlines (LUV) has just tapped bond markets with new fixed rate notes, a funding move that puts fresh attention on how its balance sheet choices intersect with the stock’s recent performance.

The fresh debt arrives at a moment when momentum in Southwest Airlines’ stock has started to rebuild. The 7 day share price return of 4.76% and 30 day gain of 6.54% contrast with a 90 day share price return that is still down 5.53%. At the same time, the 1 year total shareholder return of 39.42% and 3 year total shareholder return a little above 2x both point to a much stronger longer term ride than the 1 day move suggests.
