Booming stock market is fueling a mega-billion return to classic art and a backlash to junk

A booming stock market and increased disposable income among the ultra-wealthy have fueled a $2.2 billion fall auction season in New York, led by Gustav Klimt's "Portrait of Elisabeth Lederer," which sold for $236.4 million at Sotheby's. Other major sales include Frida Kahlo's "El sueño (la cama)" setting a record for a female artist at $55 million, and Mark Rothko's "No. 31 Yellow Stripe" fetching $62 million at Christie's. The surge is attributed to a convergence of high-quality estates coming to market—including those of Leonard Lauder, Robert and Patricia Ross Weis, and Jay and Cindy Pritzker—and renewed confidence among wealthy buyers after a stagnant period for art prices.
