I have been contributing to the TSP for about a year now with my allocation spread out evenly.I want to change it to the L Fund 2040.Do i put 100% in L2040 fund and they mange my account with the different funds?I guess my question is when i change my allocation do i put all my(100%)money in the L2040 fund if i want them to mange it for me.Any help will be appreciated and great forum.
