When the stock market gets stressed by a correction, emotions are magnified. Commentators attribute daily swings to the headline of the day.

One data point worth reviewing is from the American Association of Railroads (AAR). The AAR publishes weekly data on rail traffic.

According to the report for the week ending February 13, 2016, “total U.S. weekly rail traffic was 505,148 carloads and intermodal units, down 3.8 percent compared with the same week last year.” Total freight cars and intermodal units are down 5.8 percent compared to last year for the first 6 weeks this year. But of the 10 carload commodity groups, miscellaneous was up 27.4 percent and motor vehicles and parts were up 12.6 percent.

The sectors posting decreases compared to the same period in 2015 included, “coal, down 32.5 percent to 75,249 carloads; petroleum and petroleum products, down 23.4 percent to 11,303 carloads; and metallic ores and metals, down 15.4 percent to 19,196 carloads.”

The data points to a fairly healthy consumer sector and a supply correction in raw materials commodities. As supply adjusts to demand, prices stabilize and rebound. These are healthy adjustments for an economy on course for the old normal.
