Warren Buffett’s Favorite Indicator: Freight Car LoadingsIn an interview, Warren Buffett was asked to identify the single most important economic statistic he would choose if he was stranded on a desert island for a month and could only get one set of economic numbers. Buffett reported that his favorite “desert island indicator” would be freight car loadings. Freight car loadings measure the amount of raw materials, inputs, and supplies moving around the country every week, and this should be predictive of the future direction of the overall economy.Some data can be found at the Association of American Railroads.
