Think about that for a second. You switch and you will have to pay capital gains this year. The stock goes down and you will have paid taxes on money that you lost lol.
When you take it out of IRA to move to Roth IRA, it's considered income for that year. It will add to your tax bill. If you (as most of us) think FNMA prices are going up, it's advisable to move it to Roth while keeping an eye on your tax bill. I began moving my stocks to Roth annually from 2017 through 2024.
