@jose96 I was thinking about this yesterday. Too many service members are afraid of stocks because of risk, yet we do risky jobs. We mitigate risk in our jobs to make them less risky. You can also mitigate risk to make stocks less risky as well.
The first way to mitigate risk in stocks is to have an emergency fund. If the stock market is down and you need money at the same time, then use the emergency fund instead of liquidating stocks at a loss. Having a low risk pot allows you to have a high risk pot after it.
Second way to mitigate risk is to invest long term. TSP is a retirement account so it is forcing you to invest long term. G fund will never lose you a numerical amount of money, but it still without risk. Right there in the disclosure it says its susceptible to inflation risk. US common stock is historically proven to be the best hedge against inflation.
Lastly, the TSP forces you to dollar cost average by contributing every two weeks. Dollar cost averaging is historically proven ti reduce your risk in stocks.
Long story short, the mechanics of the TSP reduces your risk in 2 of the 3 major ways to do so. By having an emergency fund and no high interest debt (over 4.5%), you are mitigating the final piece and should be invested in the stock based funds (C/S/I).
