Plan a Portfolio Rebalance After a Market Swing

The market moved, your allocation drifted, and now you are eyeing the sell button more out of anxiety than strategy. Rebalancing works best as a rule, not a reaction. This calculates the actual drift, recommends whether to rebalance with new money or by trading, and sets a review rule so this stops being a weekly panic.

<context>
Your target asset allocation is {TARGET_ALLOCATION} but recent market moves have shifted your actual holdings away from it. Current allocation: [current percentages].

**Plan** the rebalance:
1. Calculate the drift between target and current allocation
2. Recommend whether to rebalance by selling and buying, or by directing new contributions, and why
3. Note tax or fee implications of each method in general terms
4. Set a rule for how often to check this in future so it does not become a manual chore every week
