An upward push took the Dow into positive territory, but the S&P 500 encountered resistance at the neutral line. Subsequent selling pressure has sent the broad market down to a fresh session low.
Materials stocks are down the most. Their 1.9% loss is almost twice as much as next worst performing sectors (industrials, -1.0%). Among the 30 names that make up the materials sector, Sherwin Williams (SHW 81.51, +0.12) and CF Industries (CF 129.12, +0.18) are the only two in positive territory. Steel stocks Nucor (NUE 45.99, -1.21) and U.S. Steel (X 54.24, -1.48) are under some of the sharpest pressure in the sector.
