Bloomberg Businessweek ranked the 50 top performers of the S&P 500. One REIT, Ventas, made it on the list, which included such corporations as Priceline.com (No. 1), Peabody Energy, Cliffs National Resources, Apple, Google and Gilead Sciences. Ventas ranks at No. 34 on the list. Its performance, Bloomberg Businessweek noted, was especially remarkable given the struggles of the real estate market.
