Rebalancing Frequency

Rebalancing frequency is the interval at which you sell overweight assets and buy underweight ones to return your portfolio to its target allocation. In crypto, where prices can move 20-50% in a single month, rebalancing decisions have outsized impact on returns.

Research by Shrimpy (2020) analyzed crypto portfolio rebalancing across different frequencies from 2017-2020. Their data showed that monthly rebalancing outperformed buy-and-hold by an average of 64% over the period, while daily rebalancing underperformed monthly due to transaction costs and tax events. Hourly rebalancing performed worst of all, eaten alive by fees and spread.

There are two main rebalancing approaches: calendar-based (rebalance every month regardless) and threshold-based (rebalance when any asset drifts more than a set percentage from its target, typically 5-10%). Threshold rebalancing is more responsive to major market moves but requires active monitoring.

For most crypto investors, monthly calendar rebalancing offers the best balance of simplicity and performance. It naturally implements a "sell high, buy low" discipline — trimming winners that have grown beyond their target weight and adding to losers that have shrunk below it. This systematic contrarian behavior is psychologically difficult but mathematically sound.

Tax implications matter too. In many jurisdictions, each rebalance triggers a taxable event. Quarterly rebalancing reduces tax events by 67% compared to monthly while sacrificing only a small amount of risk reduction. Consider your tax situation when choosing frequency.
