Does anyone have any recommendations for TSP fund allocation. I'm currently 42 years old, married with one child, and don't plan on using the money for at least 20 years. I am currently in the 2055 Lifecycle Fund, but worried that it might be too heavily weighted in the I Fund given the TSP restrictions on international investments. I have been reading that maybe it makes sense to do the following allocation given my long-term timeframe: 60% C, 20% I, 20% S. Does anyone have thoughts or recommendations?
I'm similar age and have a TSP. It's 100% in stocks, heavily weighted to the C fund personally, but there isn't really a wrong way to do it other than put all your money in G/F for your whole career.
I do think it's good that your are in the 2055 since that will keep you in stocks longer considering you'll be in your 70s by the time it gets to it's most conservative form. If I was you, I'd take the time to look at the allocation percentages over time and make sure the allocation over time is in line with your financial plans.
Someone mentioned it in one of the responses about how different folks manage treating pensions. I think some of the popular ideas are: 1) you don't need a bond allocation, or 2) less bonds depending on pension size, 3) <insert other ideas>. These are good things to consider as you go take a look at that allocation of your TSP over time.
One of the reasons I have mine in all stocks is when you go to withdrawal from TSP, you do not get to pick which pile it comes from from the way I understand it. So if you want 20k for the year and make that withdrawal, you just get handed the money arbitrarily from your allocation and possibly not from the pile you want. Probably nitpicky to the point that it won't matter assuming the world economy keeps ticking for the next 30-50 years, but it's something to consider. The other, bigger, reason is that TSP is not my entire nest egg, as I imagine it is likely not for you. Like another person mentioned, there is benefit to deciding how you allocate your TSP based on a holistic look at all of your assets.
Cheers
