Greg Abel initiated a major change soon after becoming Berkshire Hathaway’s top boss. He divested all of the company’s shares in Domino’s Pizza. The sale marked the end of a long stretch as one of Berkshire’s holdings. Abel reinvested the funds to buy stock in a new firm. That holding is now the conglomerate’s fifth largest investment. The Globe and Mail says the moves took place just days after Abel took over. The shift signals a clear shift in how the company picks its investments. Abel’s moves come as he takes on Warren Buffett’s old role.
