@sumitkmr Definitely this is for sure that one can create good wealth only by long term investment.
But for that you should select a bunch of good stocks.
There is no any thumb rule to select good stock, it changes time to time.
Some time ago PSU were called wealth destroyer, now every Tom Dick Harry suggest to buy PSU.
Just like there are no. of subjects, but we select a group of subject and study. We can't say maths is better or geography or psychology or economics or so on.
Like that choose some set of rules to see in stock, like valuations, growth, future market, technical, moving average or so. Dnd follow your self made rules religiously.
You will definately succeed in your goal.
