Occidental Petroleum (OXY) has become a significant investment in Warren Buffett's largest energy bet, as it becomes increasingly a balance-sheet story, a capital-return story, and a Buffett stock. The company closed at $53.12 on March 10, down 2.99% on the day after oil prices surged due to geopolitical tension and a potential supply shock, but this move was a catalyst for OXY's resurgence. The focus is now on debt reduction, with management focusing on improving the balance sheet and creating a stronger shareholder-return narrative. Despite this, the company's appeal is different as it believes it can reduce debt, improve flexibility, raise the dividend, and create more room for buybacks.
