AK Steel (AKS -16.2%) is the S&P's worst performer at this hour, as Q2 earnings and revenue fall short of estimates. Management identifies the culprit as rising iron ore prices, calling the quarter "solid" otherwise. Shares of U.S. Steel (X -8.6%), which issued its own lackluster Q2 report, Nucor (NUE -2.8%) and Steel Dynamics (STLD -2.8%) also are lower.
