I was in a similar situation while working. Was difficult for me to finance X number of stocks and build share count. Think I had topped out at about 34 companies in my non-retirement brokerage acct. A few years prior to retiring, whittled it down to 16. Have added about 6-7 in retirement. Was also financing retirement accts and bond funds/etfs.I am overly diversified with 87 stocks. Trying to whittle it down and buy more shares of the better ones.
May need 2-4 stocks in each sector to achieve about 90% diversification for the SP500.
