First of all, thanks to all who responded to my original question: viewtopic.php?f=1&t=101371
. I've read and re-read this and other posts and am now ready to make some changes.
To recap: I currently contribute the maximum to my TSP and a Roth IRA. In each of those, I'm fully invested in Target Date funds (L2040 and VTIVX ). I have decided to begin looking at my retirement assets holistically and to change my allocations to overcome the blind spots in the TSP's international holdings. I also hope to have some additional cash available in the next 12-18 months to open up a taxable account and wanted to be able to work that into my overall AA.
My (proposed) revised portfolio is as follows: Thrift Savings Plan (Traditional) -- 70%
38% C Fund
17% S Fund
5% F Fund
10% G Fund Roth IRA at Vanguard -- 30%
25% (VGTSX) Vanguard Total International Stock Market Index Fund
% (VGSIX) Vanguard REIT Index Fund Investor Shares
I've loosely based this off of Vanguard's Life Strategy Growth Fund (VASGX) and am generally comfortable with an aggressive asset allocation at this stage. I'm still young (33) and do not expect to retire until I am 65.
I would be very grateful for suggestions on revisions of these particular allocations or my strategy in general. In particular, I am uncertain as to the optimal breakdown between the G Fund and F Fund within the TSP.
