Getting the Most from TIAA-CREF’s Variable Annuity Accounts

A previous study found that a dynamic asset allocation strategy with Vanguard index funds produced better returns than models with static asset allocations. Changing asset allocation according to stock-market climate produced much higher returns with less risk. TIAA-CREF’s variable annuity accounts can similarly be used to improve returns for participants. Results for three models with dynamic asset allocation are provided whose performance and risk measurements are all better than those of the variable annuity accounts alone, or static combinations of those accounts.

Vanguard’s Actively Managed Funds With Dynamic Asset Allocation: The Best Bet For High Returns

In continuation of our previous article “How Good are Vanguard’s LifeStrategy Funds? Much Better Returns From Vanguard Funds with iM’s (MAC-Vang)20/80” we show that exceptionally high returns can be obtained from Vanguard funds, when a dynamic asset allocation strategy is employed, and actively managed funds instead of index funds are used. Using a combination of bond-, stock-, and sector-funds in the model, and switching asset allocation according to stock-market climate, provided an annualized average return of over 15% for the backtest period Jan-2000 to Jul-2014.

More Retirement Income with iM’s Improved Floor-Leverage Rule: 6.5% Safe Withdrawal Rate

The original Floor-Leverage Rule for Retirement, as proposed by Scott and Watson, calls for two parallel investments. The first one is to establish a low risk Spending Floor Portfolio with 85% of one’s funds. The second, the Surplus Portfolio, is an investment of the remaining 15% in equities with 3× leverage. If the Surplus Portfolio exceeds 15% of the total portfolio value at annual rebalancing when withdrawals are made, it is adjusted to 15% of the total portfolio value with the excess being transferred to the Spending Floor Portfolio. The problem is that 3× leveraged stock portfolios can lose most of their value. For example, they lost 94% from 2000 to 2008, which would have wiped out almost 15% of retirement capital if one had followed the Original Floor-Leverage Rule. A better approach, and one that could avoid such losses, is to time one’s exposure to equities as put forward by our Improved Floor-Leverage Rule, which is a low-risk spending and investment strategy for retirees.
