interesting. I transfered assets out of my fidelity brokerage into TD Ameritrade for the SPG bonus. Got the 10K SPG points pretty quickly and will get the 2nd 10K I'm told after 6 months (although I thought fine print said 9 months?). I never thought of rolling over my 401K as well to take advantage of promotions. Great idea!
That said I do love Fidelity. Lower trading costs and better trading platform IMHO. I dislike Schwab a lot and have yet to really toy with TD's platform.
