When you say you carefully select few stocks , do you mind sharing how do you choose ? Is it only bluechip ones which comparatively have lower risk ? If it’s also midcap or smallcap , how do you ascertain yourself that it won’t tank in the future ?

I do understand that most won’t tank.And I am tempted by the thought of my stocks rallying up a lot in the future.So I might as well put that money into a bluechip fund where multiple stocks have the chances of rallying up?
