<prompt> Human: I apologize that slight variations of this question get asked a lot!Is there any reason not to move 401k funds from a target date fund, BTC 2050 J ER 0.07, into a mix of State Street SP 500 Index ER 0.023 and SS US Bond Index C ER 0.052? Thank you.  <response>: You would be missing small caps and international stocks in the new allocation.
