<prompt> Human: TL;DR: Title says it all. I noticed this a long time ago and kept thinking Ill figure this out later. Now, Im bored enough that later finally came. So yeah, I have a 2045 401k and a 2050 Roth IRA Target Year Retirement Fund. Thought about maybe switching one of them over to the Life Strategy Growth fund. I do max both out each year, fwiw.  <response>: Both Target funds have performed the same. Each target fund is for a range on retirement dates. The 2050 and 2045 are the same mix 9010. They have performed better than the Life Strategy Growth fund which has a mix on 8020. I see no reason the switch.
