I have a question, i am planning to sell some shares of vtsax from my taxable account and will gain profit after selling. If i will sell the VTSAX, is that mean i cannot buy the same index fund on the following day??? Do you sell some of your index fund if you profit from it or just leave it and wait until you are ready to do the rebalance of the asset??? Just need some thought. This is the first time i am trying to sell the index fund. Thank you...
