A few years back, I contributed to a Roth IRA, but after realizing that a traditional IRA was more advantageous (per mad fientist blog) it has sat there with only one years contribution in it. Consequently, I have under $10k in the Roth and have it sitting in VTSMX (expense ratio .16). I think I can set up a brokerage account inside the Roth and purchase the ETF with an expense ratio of .05. I know this is a minor difference especially given the >$10k number ($1 per $1000 if I'm doing my math right), but I wanted to know if I'm correct and should make the change.
Thanks experts!
