How does portfolio rebalancing work?

Rebalancing means periodically adjusting your investments back to your target mix. Over time, winners grow and shift your allocation; rebalancing sells some of what's grown and buys what's lagged, keeping your risk level steady and enforcing 'buy low, sell high'.
