Equity-index put options written by Berkshire Hathaway Inc. started expiring in June, and the last of them will be gone by January 2026. Buffett, Berkshire’s chairman and chief executive officer, initiated the deals between 2004 and 2008 to bet that stock prices would rise in the long run. The options, tied to four major equity indexes, added a total of $2.4 billion to earnings from 2008 to 2017.
