Rebalancing is the process of periodically reviewing smallcases by their creators. It ensures that the smallcase continues to reflect the original idea. You should review & apply the update as you receive them.
Please Note:
If you skip or customize the update, your smallcase may no longer follow the original idea and may thereby impact your returns.
Your SIP (if active) will also be updated
You can check the rebalance schedule on the original smallcase page
