Rebalancing Strategies

In order to keep risk under control, you should rebalance assets quotes from time to time, so to keep them at the original percentage of the asset allocation.

Rebalancing can be performed in several ways.

At fixed time intervals:
  • Yearly: Jan 1st
  • Half Yearly: Jan 1st, Jul 1st
  • Quarterly: Jan 1st, Apr 1st, Jul 1st, Oct 1st
When a component (at least one) diverges from its original weight beyond a certain threshold (e.g. 5% or 10%).
