TSP Allocation Model (TSP)

The Thrift Savings Plan is a defined contribution retirement savings and investment plan for Federal employees
and members of the uniformed services. It is one of the most effective retirement plans in use today, but it must be
managed on an ongoing basis if you expect it to be a primary source of retirement funding.

Many Thrift Savings Plan investors are lulled into a sense of complacency by the simplicity of their TSP accounts. They
are led to believe that they can simply choose a fund, set up a contribution amount, and their retirement will grow on
autopilot. However, this is not the case. TSP members are encouraged to update their allocations frequently, but few
take the time to do this, and even fewer know how to do this strategically.

If you are enrolled or are eligible to enroll in the TSP, the TSP Allocation Model (TSP Model) can help you earn
higher returns while taking on less risk. The TSP Model is designed to keep your account allocated to the strongest
performing funds, while still maintaining adequate diversification. Like all of our investment models, the TSP Model contains
a built-in
mechanism for moving to a position of safety during severe market declines.

The chart below shows the backtested performance of the TSP Model over the last 21 years (since the TSP’s current
incarnation). For comparison, the performance of the C Fund (an index fund that tracks the performance of S&P 500), the
F Fund (an index fund that tracks the Barclays U.S. Aggregate Bond Index), and a 60/40 blend of those two fund are
included in the chart. Make sure to read this entire page to understand how the results below were achieved and how you
can apply these results to your own portfolio.

TSP Allocation Model Historical Performance

Model performance represents total returns and includes reinvestment of dividends and interest. No management
fees or transaction costs are included. Historical performance is not an indication or guarantee of future
performance.

Notice that the TSP Model was able to largely avoid the losses associated with the dot-com collapse and the financial
crisis. This was achieved by dynamically reallocating investments into the F Fund during these periods of market
turmoil. When the other funds resumed their ascent, the TSP Model shifted back into the market to capture the growth in
those funds.

Not only was the TSP Model able to outperform various allocation strategies, as well as the broader market, it did so
with less portfolio volatility and overall risk. The table below contains a series of performance metrics that allow you
to compare the TSP Model against several benchmarks.

Key Performance Highlights:

  • Over the last 21 years the TSP Model’s compound annual return has significantly outpaced that of both stocks and
    bonds, as well as a blended portfolio.
  • When compared to stocks, the TSP Model generates strong excess returns (alpha) while experiencing significantly
    less volatility (risk).
  • The reduced volatility and enhanced returns provide for notably higher risk-adjusted returns, as evidenced by
    the Sharpe, Sortino and Treynor ratios, and a positive alpha.
  • Stocks lost over half their value during the financial crisis. The TSP Model was able to sidestep those losses
    by repositioning the portfolio into the F Fund.

The TSP Model utilizes the five individual funds below to achieve its high risk-adjusted returns. Please note that
the TSP Model does not use the Lifecycle Funds (L Funds) because target date funds are not a suitable option for TSP
investors. For more information on why investors should stay clear of target date funds, including the L funds,

The specific TSP Model performance seen above is based on the following criteria and allocations:

  • The performance of each TSP fund is analyzed monthly and the portfolio is reviewed and adjusted on the first
    trading day of each month.
  • The portfolio balance is allocated to the top 3 ranked funds, based on the following allocation percentages:
TSP Model Allocations by Rank
Fund Rank: 1 2 3
Allocation 50% 30% 20%
  • If any of the top 3 ranked funds do not meet specific performance criteria, that allocation is placed in the F
    Fund.

The end result is an innovative strategy that achieves steady growth, while protecting investors from major losses
associated with market crashes. Regardless of how much you currently have or contribute to your TSP account, the TSP
Model can help you achieve better returns with less overall risk.
