YAHOO [BRIEFING.COM]: Equities began the session with an opening sell-off as disappointing earnings combined with Moody's downgrade of five Spanish regions fueled the bearish sentiment. Stocks reached session lows during the first hour before attempting to rebound. The tech-heavy Nasdaq showed intraday resilience, but the attempt to reclaim its early losses was cut short when late-day selling sent the index back near the middle of its range. As a result the Nasdaq ended lower by 0.9% while S&P 500 lost 1.4%.

Stocks in the materials space saw the biggest weakness. Among steel producers,
AK Steel (AKS 5.19, -0.32) fell 5.8% despite beating on earnings and reporting revenues in-line with Capital IQ consensus. However, based on current conditions, the company expects to incur a net loss during the fourth quarter. This includes an anticipated non-cash tax expense resulting from an expected change in the company's tax valuation allowance. Other steel producers also traded lower. ArcelorMittal (MT 15.64, -0.92) slid 5.6%, while Cliffs Natural Resources (CLF 43.55, -1.44), Nucor (NUE 40.37, -0.75), and United States Steel (X 21.90, -1.01) all lost between 1.8% and 4.4%.
