Bear of the Day: Southwest Airlines (LUV)

Southwest Airlines (LUV) now carries a Zacks Rank #5 (Strong Sell) after surging fuel costs began squeezing margins and eroding profitability.

The downgrade follows guidance management already trimmed. LUV cut full-year EPS guidance to a range of $3.25-$4.25, down from a prior outlook above $4.00. The company also halved its planned capacity growth, a defensive move that signals management sees little room to absorb higher input costs through volume. Analysts have responded by lowering estimates across the board, which is the input driving the Rank #5 designation.

The core problem is pricing power. Fuel cost increases are outpacing LUV's ability to raise fares, and the company books only 60 days in advance, limiting how quickly it can reprice for a cost spike. That short booking window means margin pressure shows up fast and recovers slowly.

Demand is not the issue. The article describes demand as strong, and new revenue initiatives show promise. In our interpretation, that makes this a cost story rather than a demand story: the top line may hold while earnings per share erodes, a setup that tends to keep estimate revisions pointing lower.
