Few reasons...
1) Few years back when I was building my capital,I used to think that if I have X amount to trade, I will do very well.....but slowly over the years my capital increased to many multiple of x lakhs...so now the capital is no issue.
2) I am not inclined to do the marketing,systems ,administration efforts needed for running a PMS. Also I dont want to answer investors who get scared with 2-3 days of market coming down in correction...I do research and stock pickings for my portfolio which is of a reasonable size.
3) I dont want to tie myself with SEBI,its regulations,reporting etc I dont have organisation for all these.
4) I still recommend stocks to few close friends and family members who are doctors,industrialist etc...and they buy from their broker....nothing is charged to them..all done in friendship....they are busy professionals and high earners so they dont breathe down my neck.As this is done free, I command huge respect from these people.
