The decision to sell the shares was as surprising as the decision to buy them. So let's move on to investing in Barrick Gold, including a 401k Gold IRA. The first thing to keep in mind is that we have no idea if Warren Buffett made this investment. He has transferred a large part of the portfolio to two investment managers, Ted Weschler and Todd Combs. While he sometimes reveals if he was behind a trade, he hasn't revealed it with regard to the investment in Barrick Gold, at least that's what I've seen.
