A bear market can sometimes throw your finely tuned asset-allocation mix out of whack. As stocks lag, your bond portfolio may start to outperform. Next thing you know, your “ideal” 70%/30% asset mix might be drifting toward a 60%/40% or even a 50%/50% split, and your actual mix no longer matches your risk profile.
You should consider adopting a portfolio rebalancing strategy—even during down markets when it’s tempting to let your “winners” keep growing while your “losers” are taking their lumps. That’s because rebalancing helps you “buy low” and “sell high”—an investing adage that’s easy to say and hard to do.
The chart below illustrates hypothetical outcomes for three different investment strategies.
Bottom line: Rebalancing is an important investment discipline, whether you do it annually or use a rules-based system to rebalance only when stocks decline by a certain amount.
