Portfolio rebalancing
Understand why rebalancing serves two functions: (1) risk control — without rebalancing, bull markets push allocations to dangerous stock-heavy concentrations; (2) systematic value investing — selling the asset class that grew (relatively expensive) to buy the one that underperformed (relatively cheap) is disciplined counter-cyclical investing.
In this lesson
Portfolio rebalancing is part of Investment Strategy & Portfolio. This preview shows how investment-universe connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.
Think about this money choice
Imagine this situation: Your target allocation: 70% stocks, 30% bonds. After a bull market, stocks grew to 85% of your portfolio. Rebalancing requires selling stocks and buying bonds.
How it works
Rebalancing serves two functions: (1) risk control — without rebalancing, bull markets push allocations to dangerous stock-heavy concentrations; (2) systematic value investing — selling the asset class that grew (relatively expensive) to buy the one that underperformed (relatively cheap) is disciplined counter-cyclical investing.
Apply it to a real decision
Real-life money moment: Your target allocation: 70% stocks, 30% bonds. After a bull market, stocks grew to 85% of your portfolio. Rebalancing requires selling stocks and buying bonds. Why is this psychologically difficult? The key lesson is: Rebalancing psychology: selling winners (stocks that just grew) and buying laggards (bonds that underperformed) runs counter to human instinct — which wants to keep winners and abandon losers.
