Frequently Asked Questions
It depends heavily on your age and risk tolerance. A classic '60/40' portfolio puts 60% in high-risk equities (stocks) and 40% in low-risk fixed income (bonds). Younger investors often opt for 80/20 or even 100% equities.
Over time, winners outgrow losers, throwing your target percentages off. Rebalancing forces you to 'sell high' on assets that have grown and 'buy low' on underperforming assets to restore your original risk profile.
