Greg Abel made his first big shift soon after becoming Berkshire Hathaway’s top boss. He sold off 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 different firm. That holding is now the conglomerate’s fifth-biggest investment. The Globe and Mail says the moves took place right after Abel took over. The shift signals a clear shift in how the company selects its investments. Abel’s moves come as he takes on Warren Buffett’s old role.
