As we can see there was good rise yesterday 10+ points but today it complete market down. I think its good time to re-enter if not already. because some reason market is on down but it will be bounce back tomorrow with all stocks.
So may be this is the time to take entry in coalindia because after few days it will give dividend so buying will done in this week till divined date.
According to my point of view today is time to buy coal india with discount price. - key point looks like there is some big position is build on price @230-238 on yesterday high.
Lets see what it say upto next week and review it on your own and put your point of view.
