BPL:
You are already booking some loss in BPL. Technically it looks that it is bottomed out and further big downside is unexpected (< 52) . Now I don't expect the stock to touch a level of 70 overnight , but yes some uptrend is expected and you can minimize the loss. So Keep a stop loss at 50 and target for 62. If it does not archive the target by oct 07 end and neither go below 52, you better move out and book loss [ I seldom suggest someone to book loss].
Ind Bank Merchants : Not tracking.
JCT Ltd avg: you bought at 6.50 and CMP is 11.58, almost 100% profit. No technical call can be made on such small scrip. I might have been in your place, I would waited for further upper circuit, as the trend generally follows for 2-3 days, after that when the price stabilizes, you can book profit.
I did not get the last one, are you talking about :
Mangalore Chemicals & Fertilizers Ltd:
You bought at 18, CMP is 41.45. Keep a stop loss at 39, if it crosses 39, sell it out. Else Wait till Oct07 end for higher level.
