In my view, different stocks play different roles in a portfolio at any given point in time.

If you had frozen the March 2020 Portfolio of PPFAS flexicap as it is then in 2 years, their domestic folio beats overseas by 2.5:1

#PPFAS

I believe PPFAS suffers from typecasting. most investors believe the differentiation is an overseas component and not other features like going into cash/ value/ safety first etc.

no one looks at tax-efficient way of looking at returns along with risk is taken/ churn happened.

Persistent/ Mphasis/ CDSL are 4 to 7 X and with meaningful weight.

IEX is now 2.5-3X (though not part of Indian portfolio)

including dividend, ITC has beaten up amazon since then

There is no scientific way to find out which stock worked well. Only fund house knows buying prices.

this exercise can be done by any investor at any given point of time from factsheet date to any date. (relevant enough in my view)
