I have a problem that doesn't seem too difficult but which is driving me crazy
I have 1,000,000 dollars.
10% in stock A
20% in stock B
40% in stock C
30% in stock D
The brokerage cost is 1% of the size of the transactions.
My question is: how much (exactly) should I buy in each stock in order to fully invest my 1,000,000 dollars?
