A breadth thrust is a sudden burst of strong participation that follows a downtrend or bear market. For GDX (NYSE:GDX) we measure the breadth thrusts on a 15 and 25-day basis. Two breadth thrusts have been triggered in the last 11 years. It appears the 15-day thrust could trigger in a few days and the 25-day thrust indicator could potentially follow in a week or two. Obviously, Gold’s close on Friday will play a major role.
