Frequently Asked Questions
What is the Rule of 110 in asset allocation?
The Rule of 110 estimates your stock allocation percentage by subtracting your age from 110 (e.g., at age 35, 110 - 35 = 75% stocks, with 25% allocated to bonds and cash).
Why does age play a key role in asset allocation?
Younger investors have decades to recover from short-term stock market downturns and benefit from higher equity growth, while retirees require capital preservation and steady fixed income.
What is the difference between stocks, bonds, and cash reserves?
Stocks offer high long-term capital growth with higher volatility. Bonds provide steady interest income and downside protection. Cash reserves offer emergency liquidity with zero volatility.
How does risk tolerance adjust standard age-based rules?
Aggressive investors add 10% to 15% more stock exposure to standard age rules, while conservative investors reduce stock exposure by 10% to 15% in favor of bonds.
What is a target-date fund?
A target-date fund automatically adjusts its asset allocation over time, shifting from aggressive equities to conservative bonds as you approach your target retirement year.
How often should asset allocation models be reviewed?
Review your asset allocation annually or whenever major life events occur (marriage, career changes, birth of a child, approaching retirement).
