By increasing shareholding in Occidental Petroleum, Buffett has contradicted one of his principles.

According to estimates from Barron's, reducing the shareholding in Apple caused Buffett to miss out on over $35 billion in earnings. Meanwhile, Occidental Petroleum and Sirius XM have both seen significant declines this year, with stock prices consistently below Berkshire's average buying cost. Buffett seems to be "pulling flowers and watering weeds."
