If you want to set it and not touch it or look at it again until you retire its pretty good.
Otherwise I’m not a big fan of it. The G and F fund combined make up 15.5% of the fund which I think for a person that is 24 is too conservative, my own portfolio currently has 10% in bonds. I’d recommend you set your own allocation to closer to what TSP Paul is recommending.
Currently the L-2050 is allocated as follows
I agree with Morgan in that I’m not a big fan of the L funds. It really depends on your risk tolerance and what you are comfortable with. Since I’m closer to retirement, I am a little more risk adverse and a little more pessimistic on our current economic outlook but I do think that you should be primarily in stock at your age. 25% in I is a little riskier, 15% in G
& F is less risky. If we go into a bear market or recession, all stock funds are risky.
