¹Life starting dates for TSP funds are August 31, 2004. TSP Coach strategy has been in use since August 2004.

This table shows the risk based on monthly returns for each of the TSP Funds, Lifecycle Funds and TSP Coach. My TSP Fund allocations have reduced my risk, but does not lower it to levels that inhibit my returns. While I utilize the Sharpe Ratio in my calculations, and risk is an important part of this equation, I also perform proprietary calculations to ensure that the often times conservative nature of the Sharpe Ratio does not limit the performance of my Thrift Savings Plan investments.

I started with an initial value of $10,000 on January 1, 2005 and then compared my returns to other fee based TSP newsletters based on the information available on their websites. In cases where their programs started after 2005, I started them at the TSP Coach end of year fund value in order to provide an easy comparison. Additional comments are noted in the table.
