Your TSP’s stock and bond funds: Which is safest?

When people go into something like the Thrift Savings Plan, they think of it as a long term investment. Most believe that things like the bond-index F fund and the treasury securities G fund are the safest. Most also concede — and the long term numbers bear it out — that stocks outperform bonds over time. But what about the F fund out performing the G fund? If that’s the case, and the numbers show it to be true, which is the safest?

Financial planner Arthur Stein says that “safe” is a relative term. And he also says many feds don’t understand that their TSP retirement nest egg is not really an investment. He’ll be my guest today at 10 a.m. EST on Your Turn. You can listen live here or on the radio in the D.C. area at 1500 AM. Stein has lots of clients who are feds, active and retired. Some of them have more than a million dollars in their TSP account. Here’s the guest column he wrote to explain the “investment” part of your TSP.

If you have questions, send them to me before showtime. Meantime, here’s what he wrote:

Are TSP Funds Really an Investment?

Your TSP account is not an investment. The TSP Funds are not investments. Your account and the funds in it are a way to own two different investments – stocks and bonds. Depending on the fund you choose, your money is used to purchase either stocks, bonds or, if you use the L Funds, both stocks and bonds.

By choosing different funds, you determine the allocation between stocks and bonds and the types of stocks and bonds in your TSP account.

This is important because stocks and bonds have very different historical records for performance and volatility.

Over longer time periods, the stock funds usually outperformed the bond funds.

Past performance is no guarantee of future performance and, except for G, all funds carry the risk of loss. However, I do not know anyone predicting that bonds will outperform stocks over long periods of time in the future.

Over both short-term and long-term time periods, the stock funds were much more volatile than the bond funds.

Nearly Useless Factoid

New York architect Henry Bacon modeled the Lincoln Memorial in the style of a Greek temple. The classic design features 36 Doric columns outside, symbolizing the states in the Union at Lincoln’s death. The building measures 204 feet long, 134 feet wide and 99 feet tall, with 44-foot columns.
