<prompt> Human: This is currently my 401k asset allocations and I have funds invested in a 2040 and 2045 funds. Is there any purpose in this or should I re-balance and choose one or the other?Current investments -  <response>: You can sort of create a 2042.5 fund by doing that but theres probably not enough a difference between 2040 and 2045 for that to matter. Id consolidate things just to make it simpler.
