Greg Abel Raised Berkshire's Delta Stake 44% to 8.7%, Reversing the Airline Exit Buffett Made in 2020

Berkshire Hathaway’s cash pile has started to shrink as the company, under CEO Greg Abel since January 2026, returned to stock buying after a long stretch of net selling. By the first quarter of 2026, Berkshire had reached a record $397 billion in cash in its portfolio. In the second quarter, it became a net buyer for the first time in 14 straight quarters, purchasing about $23.5 billion in stocks and selling $3.7 billion. A key move was adding 17.5 million Delta Air Lines shares, boosting the stake 44% to 8.7%, now worth $5.4 billion.
