28y/o and approximately $43k in my Roth IRA with Vanguard. I’m currently \~75% VFIAX and \~25% VIMAX, for some reason, and have been researching VTSAX/VTIAX. Am I overthinking it? Been successful with what I have so far, but looking to find better efficiency if able.
Feels like it’s worth also asking about my TSP, which is about $103k in my TSP currently split at 80% C and 20% S.
