Greg Abel initiated a major change soon after becoming Berkshire Hathaway’s top boss. He liquidated all of the company’s shares in Domino’s Pizza. The sale concluded a long stretch as one of Berkshire’s holdings. Abel reinvested the funds to buy stock in a separate firm. That holding is now the conglomerate’s fifth largest investment. The Globe and Mail says the moves took place shortly following Abel took over. The shift indicates a clear shift in how the company selects its investments. Abel’s moves come as he steps fully into Warren Buffett’s old role.
