I have been following a few momemtum stocks e.g. GDL, DRL, BEML, IDFC, SAIL, ESCORTS,..... However, I happen to enter the stocks, the day it shoots up mostly at higher levels. Then it starts retracing at higher leveles for a few days, which I find unable to hold. Again it starts shooting its second leg. I would like the seniors to guide me about retracement levels in simple language...........................................
