Title says everything; I just opened Roth IRA account at December of 2025 and looking for some insights for investment options. I opened my account in Fidelity and current balance is $14500 (7000 from 2025, 7500 from 2026)
While investing 100% in VT seems like a solid idea as it does the demographic diversification for you, I ran into couple mutual funds available by Fidelity that do not have transaction fee (FXAIX, FSKAX, FTIHX, etc...). FXAIX especially was interesting as its expense ratio was 0.015%, when that of VT was 0.06%.
1) For those who have been in this journey of long-term investment for quite some time, are differences in expense ratio and transaction fee really that impactful? If not, what other attributes are, if any?
2) My two options in my mind at the moment are ***100% VT*** vs ***65% FXAIX + 35% FTIHX***. Which of these two seems to diversify risk better? If both options do not sound right, which is possible, any recommendations are welcome.
Advice is much appreciated.
