Is this your first RMD? I suppose you want to take the full RMD and use it to buy stocks. Then pay the taxes when you do your tax return? You will get a 1099R form for it in January or Feb to enter into your tax return. It will also have codes you need to enter into your tax return. It will increase your income so be sure to have enough withholding or estimated payments to cover the extra tax so you don't have a underpayment penalty.
