I am currently a resident with a Roth 401k through the hospital I am working for. I am planning on rolling this over to a Roth IRA upon entering my job as an attending.

My current asset allocation is roughly 75% US large cap index, 20% International index, and 5% US bond index. In thinking about the best tax situation, I understand low tax efficiency items should be placed in tax efficient accounts like a roth IRA.

So my question is, on rolling over into the roth ira, do I then get to change my asset allocation including type of fund (for example opening a REIT index fund) or are the 3 funds just placed into the new account? I am not sure if the lump sum of the money is available to me to reinvest as I see fit or if the funds themselves are just transferred into the new account.

Any advice would help.

Thanks
