NEW YORK, NY--(Marketwire - Feb 26, 2013) - Aluminum industry is going through demand and supply imbalance, where supply surpassed demand, leading to price glut. The impact of the situation is clearly visible on the bottom-line of the leading companies. Noranda Aluminum Holding Corp. (NYSE: NOR) announced higher fourth quarter losses despite posting higher revenue. The depressed pricing exerts pressure on the company's margins. On the other hand, Alcoa Inc. (NYSE: AA) reported better results as it has a more diversified product portfolio. The sector is likely to see an uptick with improvement in the general economy and in specific sectors like auto and machinery.
