(Reuters) - Small and mid-cap industrial stocks fell on Friday after U.S. President Barack Obama unexpectedly asked the Environmental Protection Agency to withdraw a plan to limit smog pollution.
The President's comments followed a grim report on the labor market that U.S. employment growth ground to a halt in August with the unemployment rate stuck at 9.1 percent. The weak jobs report triggered a broad market sell-off, sending major indexes down more than 2 percent. The midcap industrials sector index .4GSPI fell 4.3 percent.
Shares of Koppers Holdings (KOP.N) fell 8.3 percent to $29.69. The company provides carbon compounds and commercial wood treatment products to aluminum, railroad, specialty chemical, utility, rubber, concrete, and steel industries.
