Appreciate the response! Yes, maxing out Roth IRA on top contributing to 401K, HSA etc. all to sit there for a minimum of 30 years.
Just didn't how big of a risk it was to put my entire Roth IRA into one fund (even though it's a mutual fund, which should be pretty safe being that it will sit there for 30 years).
Still a little new to investing, so always nice to double check with this smart group!
