Sotheby’s CEO William Ruprecht is riding high times at the auction company. “Will we have the top lot of the season? Who knows? In the first six months, we grew about twice as fast as Christie’s. But we’re not in a race with Christie’s. We’re not in the same game. We focus on the high end, not on the mass market. We don’t sell Star Trek memorabilia as a major part of our effort. We don’t do online sales. We brought that to the art market five years ago, and we ditched it. Guess why.”
