The simplicity of TSP is both a blessing and a curse! With only 5 core TSP fund options, investing in the TSP is very simple. There are 3 stock index funds, 1 bond index fund, and a special kind of money market fund. You can mix and match within the 5 funds or utilize the L funds which do the fund allocation for you based on your expected retirement date.
The C fund tracks the S&P500 index. The ticker symbol for the index is $SPX or SPY as the exchange traded fund (ETF)
The S fund tracks the Dow Jones U.S. Completion Total Stock Market Index. The ticker symbol for the index is $DWCPF or VXF as the ETF.
The I fund tracks the Europe, Australasia, Far East Index. The ticker symbol for both the index and the ETF is EFA.
The F fund tracks the Bloomberg Barclays U.S. Aggregate Bond Index. The ticker symbol for the index and ETF is AGG.
You can put these ticker symbols into any charting app or website to create a price chart of the corresponding TSP fund.
The G fund is a special type of Money Market fund created solely for TSP investors. There is no ticker symbol. The rate of return is tied directly to the FED Funds Rate. When interest rates are coming down, the rate of return for the G fund is declining. When interest rates are moving up, the rate of return of the G fund is also moving up. Most importantly, the G fund cannot have a negative quarter by statute. You can never lose your principle when invested in the G fund.
The L funds do not have ticker symbols. They are combinations of the 5 core TSP funds, reallocating quarterly to decrease exposure to the stock funds as you progress along in your career. The objective is to decrease risk exposure to the stock funds as you get closer to retirement.
The Mutual Fund Window (MFW) is an option added to the TSP fund line-up in 2022. The MFW enables TSP investors to transfer up to 25% of the amount of their TSP account into a separate, self-directed Mutual Fund account. The MFW gives TSP investors access to 5,000 +/- mutual funds encompassing virtually every possible asset class. The MFW is completely separate from core TSP and is not governed by the TSP rules for reallocation. Restrictions and fees apply.
There are 2 buckets of money associated with your TSP account. The first is the new money that you contribute to TSP each payday. This bucket is relatively fixed. It only changes when you change the amount you contribute. If you want to change the funds to which your new money is going, you click the Change Your Investment Mix tab and select Future Contributions Only.
* There is NO LIMIT to the number of times you can switch funds for FUTURE contributions *
There are 2 critically important rules to understand when actively managing your TSP account. The first is the "2 Move per Month Rule". While this seems very straight forward, the application of this rule can be tricky...
Each calendar month you get two unlimited moves between the core TSP funds. You can change the % invested between any of the 5 core funds and the L funds. After the second move in a calendar month, any additional move can only increase your holding in the G fund. From a tactical perspective, if you use your 2 moves early in the month, your options to maximize any market gains later in the month are extremely limited. We go into great detail describing the application of this rule, with examples, in the e-book. It's a MUST READ!
While we can track the indexes to which the core TSP funds are associated on a minute to minute basis, the TSP funds themselves are calculated after the market closes each night. If you submit request to reallocate funds before 1200 PM East Coast Time, you will get that day's closing price. If your request is made after 1200PM East Coast Time, you will get the next trading day's closing price. This can be extremely confusing! Again, we go into great detail, with examples, in the e-book.
Understanding your 2 buckets of money, and the restrictions that apply to each, is CRITICAL to effectively maximize your TSP account!
