Here I am in my early thirties, a rollover IRA at Fidelity from my first employer, 401k at Vanguard with my second, and about to enter into my new employer's 401k with an assortment of otherwise unrelated funds. Things are starting to get complicated. Fidelity has been doing fine by me lately, although I remember a long period of disappointing returns. Vanguard offers some nice options, but performance has been lagging lately. The new 401k plan doesn't seem to offer anything interesting, other than the Vanguard Index 500. I don't plan on touching any of this money until I retire, and I am inclined towards an aggressive mix, but I'm not sure what the pros and cons are of having my portfolio distributed among several institutions. Should I consolidate under one or two umbrellas, or maximize my options by keeping all three accounts? I have initiated the process to convert the Vanguard 401k to a rollover IRA. Then, assuming I can handle the tax hit, I will convert this IRA and/or the Fidelity IRA to Roth IRA's. The new 401k looks like it will be invested 100% in VFINX. Allocations in the IRA's will be moved to FMAGX and VFINX. With this distribution, I'm really not taking advantage of my many investment options, but it appears to have the best potential for long-term growth. Anyone care to comment?
