This is absolute Mayhem,keep this etched in your mind,needless to say that all investors are having nightmare.What have we learnt & vouch never to repeat in future.
1) Stop Loss ,an absolute must,for optimistic guys,plz atleast follow Weekly Chart to derive the Stop.
2) Learn to Hedge,Mini Nifty is being created for that purpose only.
A crude example to clear the conceptual part for uninitiated:=
Think having 2 one litre glass container in 2 hand,on the Left is portfolio,say it's value 5 lacks,comprising several stocks.Now find out each's Beta and multiply by each stocks value,total it,then you get a new value than original 5 lacks,then calculate how many number of Mini-Nifty Lot to be sold.
So the left hand glass container diminishes & almost the same amount increases in right hand container(where we have Mini Nifty Short).
If the opposite happens means Mkt goes up the Right hand container's Loss is compensated by Left hand containers gain.This is very elementary way to touch the conceptual part,so when we Hedge we actually LOCK the Profit & also the Loss.
Once dust settles down we close the right hand container (Mini Nifty Short),atleast we can have a good night sleep.
