Finding stocks following performance of certain investor, like BRK.B for Warren Buffet
A couple points, first you don't point out what investors you want to invest with, and second BRK.B does not track anything; it is just a very small slice of his entire holdings BRK.A minus the voting rights. One solid way to go would be to buy BRK.B and also a tech ETF like QQQ, or XLK, ..or both.
