The idea behind this is
First of all, I will try to get a grasp and understanding over the sector. That is, if a sector is positive and giving indications of going up, then the scripts of that sector should only be analysed for upside moves. There will be some scripts which will not go up, despite the sector being positive. But, we can easily identify and ignore those scripts. (Vice-versa for negative movement of the sector)
Then, I would try to find out if the heavy-weights of that sectors are listed in Nifty, if yes, how much weight they carry in the Nifty. Because, I have observed that Nifty did not carry any of the scripts of the BSE sector Consumer Durables.
following are the scripts listed in consumer durable index of BSE
Bajaj Electric
Blue Star
Gitanjali Gems
Rajesh Exports
Titan Industrie
Videocon Indust
VIP Industries
Whirlpool
and none of them is in Nifty. Now, the index of these scripts i.e. consumer durable index is showing that it has a signal for shorting. But simply because none of these scripts are listed in Nifty, I am avoiding it. My priority will be to first understand one index and its ingredients. And only after having a comfortable situation, move ahead.
Third is the weightage of each script in Nifty analysed along with the sectoral strength. For example, script xyz is carrying reasonable weight in Nifty and that script is also having reasonable weightage in the concerned sector to which it belongs. In that case, the movement of that(such scripts) will have more impact over the movement of Nifty. And that may help in deciding the expected movement of Nifty.
Fourth is, I have observed that there is an indirect though significant impact( on the overall shares ) generated by movement of indexes. Like if the Nifty is going down, even the scripts which are actually strong may not move up as expected, while the scripts which are weak will go down very sharply. Therefore, this info will also help in choosing the scripts carefully. For example, for the past 3-4 days, I am only trying to find out the scripts to go short. Even if the same script is having an upside move/signal, I am simply avoiding it because I found market breadth to be negative. And it has paid me. because the upmovement has remained restricted significantly, despite the script being strong, while the downside movement was significant and sharp.
Thanks big bro and please comment and help me.
