Greg Abel took a bold step soon after becoming Berkshire Hathaway’s top boss. He liquidated all of the company’s shares in Domino’s Pizza. The sale ended a long stretch as one of Berkshire’s holdings. Abel used the proceeds to buy stock in a different firm. That holding is now the conglomerate’s fifth largest investment. According to reports the moves took place shortly following 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.
