Today’s stock chart scan examines Northgate Minerals (NXG) and Abercrombie & Fitch (ANF). Northgate exhibits a large symmetrical triangle pattern nearing its apex. With favorable precious metals prices and higher margins NXG could be set for a move higher. Abercrombie shows a classic head and shoulders formation with a neckline of $30.00.
