Greg Abel took a bold step soon after becoming Berkshire Hathaway’s top boss. He sold off 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 different firm. That holding is now the conglomerate’s 5th-largest investment. According to reports the moves took place shortly following Abel took over. The shift indicates a clear shift in how the company picks its investments. Abel’s moves come as he assumes Warren Buffett’s old role.
