You are experienced and know how to play Operator driven stocks.... But to ensure that someone innocent doesn't get lured seeing the sort of Returns they generate in a very short time, here is one of the examples of Operator Activity.... It's the Daily Chart of Shree Ashtivinayak Cine Visions Limited....
It's okay if it continues to hit Upper Circuits.... But the day it would start hitting Lower Circuits, you won't be able to get out unless it's atleast 1/4th of the High (and possibly even lower - it was 1/10th in case of Shree Ashtivinayak).... Not because you don't want to book losses, but because of Lack of Buyers....
Edit: I personally know someone who bought it at the High... When it was about 47-48.... He is still holding it in his Portfolio....
