Latest asset allocation quarterly reviews

December 2024 update – Review to 30 September 2024

The latest Willis Towers Watson (WTW) parameter review of the economic assumptions which underpin the optimised portfolios available through our platform sees slight changes to asset allocations this quarter with a circa 2.5% average portfolio turnover. The story of the quarter was one of decreasing yields across investment markets. 

As usual, the reallocations seen have been driven by the relative changes in the return assumptions, with only relatively minor changes in volatility this quarter. All asset classes have seen decreases in their return assumptions compared to the last update. There has also been an accompanying decrease in volatility, except for Cash, International Fixed Interest and Property - whose volatility remains unchanged from the previous quarters’ assumptions.

The assumptions have a 10-year time horizon, which are built on a combination of both short and very long-term assumptions. The short-term assumption for Cash has decreased this quarter. As risk asset return assumptions are calculated based on a risk premium above the local cash rate assumption, the decrease in Cash has in turn led to a decrease in the return assumptions of all other assets. Fixed Interest return expectations have also decreased this quarter because of a drop in short-term yields, however we expect these to trend upwards over the longer term.
