Can this skill handle multiple account types?

Yes, it includes logic for cross-account rebalancing across taxable, IRA, 401(k), and Roth accounts to optimize for household-level tax efficiency.

How does it assist with tax management during rebalancing?

It prioritizes using cash flows for rebalancing, identifies specific tax lots for selling, and integrates tax-loss harvesting to offset capital gains.

Does it account for trading costs?

Yes, the skill factors in commissions, bid-ask spreads, and market impact to ensure the benefits of rebalancing justify the implementation costs.

What rebalancing strategies does this skill support?

It supports calendar-based, threshold-based (band), and tax-efficient rebalancing strategies, including the Leland model for calculating optimal no-trade zones.

Implements professional rebalancing strategies to maintain target asset allocations while optimizing for taxes and transaction costs.

The Rebalancing skill provides a comprehensive framework for managing portfolio drift through calendar-based and threshold-based strategies. It enables Claude to calculate optimal rebalancing bands using the Leland model, assess the rebalancing premium through volatility harvesting, and implement tax-efficient execution across multiple account types. By integrating transaction cost analysis and tax-loss harvesting logic, it helps wealth managers and investors maintain investment discipline and risk profiles while minimizing the friction of market movements.
