TSP Seasonality Strategies

The best TSP strategies for 2026 use data-driven seasonality analysis to rotate between the C Fund, S Fund, I Fund, F Fund, and G Fund based on historical monthly performance patterns. Apex Equity's backtested strategies have shown CAGR as high as 20%+ over 10-year and 20-year periods, significantly outperforming traditional buy-and-hold approaches and the TSP Lifecycle (L) Funds.

Our top-performing strategies include the A10 (optimized for 10-year returns), A20 (optimized for 20-year returns), and A30 (optimized for lowest volatility). Each strategy is backtested against real TSP fund data so you can compare performance before subscribing.

TSP seasonality strategies analyze decades of historical Thrift Savings Plan fund performance to identify recurring monthly patterns. For example, certain TSP funds like the C Fund or S Fund tend to perform better in specific months of the year. By shifting your allocation to the historically strongest fund each month, you can potentially capture higher returns than staying in a single fund year-round.

Each month, our system evaluates the optimal fund allocation and sends you an alert with the recommended changes. You then log into your TSP account and execute the interfund transfer yourself.

Yes. Our backtested TSP seasonality strategies have consistently outperformed the L2065 and other Lifecycle Funds over 10-year and 20-year periods. Lifecycle Funds use a static target-date approach that gradually shifts to bonds as you age, which can limit growth potential. Seasonality strategies actively rotate between TSP funds based on historical data, capturing stronger monthly returns while managing risk through strategic allocation to the G Fund or F Fund during historically weaker months.

With Apex Equity's seasonality strategies, fund allocation changes are recommended on a monthly basis. You'll receive an alert at the beginning of each month telling you exactly which TSP funds to allocate to and at what percentages. TSP allows two interfund transfers per calendar month (with unlimited additional transfers into the G Fund), so our monthly rotation approach stays well within TSP's transfer rules.

TSP seasonality strategies work entirely within the existing TSP system using the standard interfund transfer process available to all federal employees, military members, and veterans. You never move money out of TSP or give anyone access to your account. The strategies use only the five core TSP funds (C, S, I, F, and G), and many strategies include the G Fund as a safe haven during volatile months to help manage risk and reduce maximum drawdown.

The optimal TSP fund allocation changes each month based on seasonality data. Rather than a one-size-fits-all answer, Apex Equity subscribers receive monthly alerts with the exact recommended allocation percentages across C, S, I, F, and G Funds. Our strategies are backtested over 10 and 20-year periods so you can choose a strategy that matches your risk tolerance. Explore our free backtester to compare strategy performance before subscribing.
