A quick question for all you financial wizards out there:
The best long-term approach to investing seems to be dollar-cost-averaging into a diversified set of index funds. Is there a way to do this without paying a commission through your broker every time you make a purchase? For example, if I have an account through TD Ameritrade and want to put $100 a month into Fidelity's Total Market Fund, is there a way to do this without paying the $9.95 commission every month?
Thanks.
