Keep in ur radar, Prabhjeetrana's technical comment "Lets see, a closing above 75 for 2 days will mean resistance taken out "
Regarding gud/bad news is concerned - demerger of this stock itself is a big news.
I have done some analysis at my end, including technical comments from few ppl and it is also based on couple of news(one was of demerger expected)...i expected some resistance at this level, but to be honest not a drop of around 5% in bullish market.
Since i'm not aware of any -ve development in between few hrs, i assume it is a buying oppurtunity and nothing to panic.
Keep watching this stock for couple of months(Mid Term), even if u r not invested in it.
