Delta Air Lines Inc (NYSE:DAL) shares are retreating Monday. Berkshire Hathaway revealed a major new position in the airline. Here’s what you need to know.

Berkshire Takes A Large New Stake

Delta is pulling back after today’s highs. Berkshire Hathaway disclosed a sizeable new investment in the carrier in its latest quarterly filing, CNBC reported. The conglomerate purchased $39.8 million Delta shares worth $2.6 billion at the end of March, making it one of Berkshire’s largest positions.

The buying activity marks Berkshire’s return to the airline sector under new CEO Greg Abel.

A Notable Shift From Berkshire’s Previous Airline Exit

The new stake stands out because Berkshire fully exited its U.S. airline holdings six years ago, when Warren Buffett sold more than $4 billion worth of positions in United, American, Southwest and Delta. Buffett said at the time that the pandemic had permanently changed travel demand.

Delta Air Lines’ Trend Is Doing The Heavy Lifting

Technically, Delta is still wearing the bullish uniform. The stock is trading about 0.9% above its 20-day SMA at $69.96 and roughly 10% above its 200-day SMA at $64.21, keeping the longer-term trend pointed up. The 20-day SMA sitting above the 50-day SMA adds to the constructive posture, and the golden cross from September 2025 remains the kind of longer-term tailwind trend traders don’t like to fight.

Momentum isn’t overheated, either. RSI at 52.54 is basically the market shrugging: not stretched, not washed out, just coiled. Zoom out further and the narrative stays friendly — 37.98% over the last 12 months, and still within striking distance of the 52-week high at $76.39. That’s why the nearby levels matter: $74.50 is the ceiling where rallies can stall, while $66 is the floor bulls want to keep unbroken if the broader market’s softness spreads.
