A recent update to the Market Assumptions within the software is now available.
What do these changes impact?
Note these changes to the Market Assumptions will not affect the plan if you have chosen to grow all investments and pensions by Entered Growth Rate.
Market Assumptions are used when a plan is grown by Portfolio (Asset Allocation). Therefore, these changes will impact investments growing by Portfolio. See here for more information: Growing an Investment or Pension using a Portfolio with Asset Allocation *AdviserGo*
The new defaults for the UK will be the Dimensional UK Market Assumptions 2026 for new clients created in subscriptions if your firm does not have either our white-labelling service where we build in your own assumptions or self-managed Custom Market Assumptions.
If you'd instead like to enter your own Market Assumptions you can buy a Rebrand of the software to include these or they can be self-managed using Custom Market Assumptions. See here for more information: Rebranding - About Voyant's rebranding / white labeling service or How to add custom market assumptions to your subscription.
Asset Classes
Due to the considerable differences between the asset classes used in these two sets of assumptions, we were unable to derive a suitable one-to-one mapping that would allow the old set of asset classes to be converted automatically to the new.
How do you update the Market Assumptions
Before updating to the new Market Assumptions, Update and Promote your plan, to save the previous version. See this guide: How to update the start date of a plan
Then:
- Go to Plan Settings > Market Assumptions and the Dimensional UK Market Assumptions 2026 will be shown. These are the assumptions now being used by your plan.
-
If you accidentally click 'Change Market Assumptions' and want to undo the change:
From the Dashboard, go to Plan Settings > Market Assumptions.
Click 'Change' on the right hand side shown as in the screen shot below
The assumptions for each selection are shown in the window that appears below.
- Select the 'Market Assumptions' as appropriate > Click 'Apply Changes' > then click 'Done' to save the changes:
Note if you do not update to the Dimensional UK Market Assumptions 2026 an error message will not appear when you open a client record stating these assumptions are no longer updated.
Note if you used asset allocations in a client's plan, created using one set of market assumptions, those asset allocations may no longer be valid if you change the plan to use a different set of market assumptions. This would typically be the case if the asset class names differ between the two sets of assumptions.
When you update a client's plan to use a new set of assumptions (click here for how to do this) you may see errors in the plan, if the asset class names are different from the original assumptions.
To fix this, firstly edit the default Asset Allocation in Plan Settings for the plan to one that works with the new market assumptions. This may resolve all of the errors in the plan. See here for more information: How to correct Asset Allocation errors after switching from one set of Market Assumptions to another.
