Warren Buffett's Successor, Greg Abel, Just Plowed $27 Million Into a Virtual Monopoly (No, Not Alphabet!)

Greg Abel, who took over Berkshire Hathaway after Warren Buffett's retirement, purchased $27 million worth of Sirius XM stock, increasing the company's stake to over 37% ownership. Abel is attracted to Sirius XM's status as a legal monopoly and its revenue model, which relies 76% on subscriptions rather than advertising, providing more stable cash flow during economic downturns. The stock trades at a reasonable valuation of 10x 2027 forecast earnings.
