Though many investment professionals swear by rebalancing, some research shows that it’s not as important as people once thought. In The Little Book of Common Sense Investing, John Bogle writes, “Rebalancing is a personal choice, not a choice that statistics can validate. There’s nothing the matter with doing it…but also no reason to slavishly worry about small changes…” In other words, rebalance if your asset allocation is way out of line but don’t worry about small changes — especially if you’d end up paying a lot of fees by rebalancing.
