I have recently rolled over 70k from my 401k to a traditional IRA. I will not be making contributions to this account as my contributions go to my 401k first up to employer matcg, then the rest in my Roth IRA. I’ve rolled over these funds to a Traditional IRA instead of Roth to avoid the I come tax hit. But being that this account will just have a one time deposit of 70k and no monthly contributions, is a Target Date Index Fund still a good option to invest the full amount in for the long term? 30+ years?
