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 marked the end of 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 5th-largest investment. It was reported that the moves took place right after 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.
