<prompt> Human: Please tell me whats good, bad, and ugly about the Vanguard Target Retirement 2045 Fund.  <response>: Good: The fund is diversified across US and international, stocks and bonds. The fund changes the proportions held in these asset classes very slowly as you approach the year 2045, to be more conservative. The fund rebalances daily so it doesnt stray from its asset allocation. It is a set-and-forget option if its your only investment and you agree with its glide path.Bad: The cost ratio 0.16 is lower than lots of mutual funds, but you technically could build your own collection of a few funds for less, though it wouldnt be rebalanced and reallocated for you automatically. The asset allocation isnt something you can change. If you have other investments, you need to do some math to assess your allocation. It might not be optimally tax efficient, if you are trying to prioritize placing dividend generating assets in tax deferred space.Ugly: VTIVX is kinda an ugly name.
