Greg Abel took a bold step soon after becoming Berkshire Hathaway’s top boss. He divested all of the company’s shares in Domino’s Pizza. The sale concluded a long stretch as one of Berkshire’s holdings. Abel used the proceeds 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 just days after Abel took over. The shift indicates a clear shift in how the company picks its investments. Abel’s moves come as he takes on Warren Buffett’s old role.
