Hi Chris,
Rebalancing typically performs well in volatile markets. The large daily swings can help increase returns. Every situation is different, so in bear markets it depends on what kind of bear market. For example, long term slowly declining asset value is never good. I can write an article at some point that details the different cases and how they perform with rebalancing. Let me know if you have any other questions! There are a lot of different situations, so each situation has different advantages or disadvantages with rebalancing.
Thanks,
