How many stocks do one usually holds on to and why?

Currently i have 1 ETF, and 13 local stocks in my portfolio which is manageable.
Periodically i wll review the perfomance of the stocks, plan to review n divest 1 or 2 stocks(which are not performing, at an appropriate time n share price) so that i can consolidate my shareholdings in the better performing stocks in my portfolio.

Hi there, our blog article on "What is The Perfect Number of Stocks to Have in Your Portfolio?" might help you.

"In the book Investment Analysis and Portfolio Management, authors Frank Reily and Keith Brown conducted a set of studies of randomly selected stocks and found that:

“…about 90 per cent of the maximum benefit of diversification was derived from portfolios of 12 to 18 stocks.“

To put it in another way, you get to enjoy about 90 per cent of benefits brought about by diversification, by having about 12 to 18 stocks in an equally weighted portfolio diversified over sectors, industries and geographical locations."​​​

I would say depending on indivdual.

Maybe this will give you an insight: https://seekingalpha.com/article/4418152-how-ma...

"Rather than trying to figure out how many stocks should be in your portfolio, you want to determine the max level of exposure to an individual investment you are comfortable with on a cost basis, and stick to it."

It's hard to monitor too many so I only have 8 stocks + 1 ETF. At the moment, my top 5 holdings are 71.3% of my portfolio.

Some folks will say the sweet spot is 10-15 stocks. I think you can have that, provided your portfolio is in the $100Ks.
