Let’s say I put $150k in a taxable account into VOO and it goes up 20% to $180k over a couple years. (Long term gains)
I then decide I only wanted $50k of principle invested, so I sell $100k.
My account value is now $80k.
In the long run, how would I keep track of my gains, if I’ve already realized the gain on $100k of the shares, but the profits are still showing in the account?
Would I be better off selling the entire account and opening a new account that way future gains are easier to keep track of?
