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 reinvested the funds to buy stock in a new firm. That holding is now the conglomerate’s fifth-biggest investment. According to reports the moves took place just days after Abel took over. The shift indicates a clear shift in how the company chooses its investments. Abel’s moves come as he steps fully into Warren Buffett’s old role.
