Jim, I would first do the homework Kristen wisely suggests.

After that, assuming that TDA doesn't come out way ahead, I would consolidate at Fidelity.

First, TDA doesn't specialize in 401(k) plans, and therefore it should be easier to move the IRAs to Fidelity than to move the 401(k)s away from them.

Second, Fidelity has its own extremely competitive index fund offerings, and TDA has nothing comparable. These funds can be excellent choices for retirement accounts.

Finally, Fidelity offers some perks (lower commissions, preferred customer service, etc.) if your assets cross certain levels. Consolidating there should get you closer to those key "breakpoints".

Having said that, they are both reputable brokerages with generally competitive offerings, so you can't go too wrong either way.

Hi Jimbo,

First I'd figure out how much it will cost to sell your positions and move your business elsewhere. I'd call each firm and ask them to calculate this cost for you.

Next, I'd look at each firm's fund selection. Do both firms offer a menu of funds that meets your needs? Fidelity and TD Ameritrade have a wide selection of funds - so I'm guessing you're OK either way you go here.

Finally I'd look at the brokerage's fees, the availability of advice and the firms' websites and customer service. You've worked with both firms so you should have an insider's perspective on these features.
