Question: What is better. Traditional or Roth IRA? I have my Roth IRA invested in the Vanguard Total International Stock Index Fund (VGSTX)? I am 38 years old.

Answer: While this subject is not free of doubt, I prefer the Roth IRA. Both the Roth and traditional IRA's are tax-deferred accounts. But, unlike a traditional IRA, Roth IRA contributions are made with already-taxed income.
