Latest asset allocation quarterly reviews

September 2024 update – Review to 30 June 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 4% average portfolio turnover. The story of the quarter was one of increasing yields across investment markets.  Note that because the asset allocations were left unchanged last quarter, our comparison is against the review done to 31 December 2023.

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 had increases in their return assumptions compared to the last assumptions update, and an accompanying increase in volatility, with the exception of both Cash and UK equity, the latter reducing in volatility.

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 assumptions for Cash have increased this quarter and, as risk asset returns are calculated based on a risk premium above cash (local cash rate) assumption, this increase has in turn increased the return assumptions of all other assets. Fixed Interest return expectations have increased in the latest expectations, in line with an expected upwards trend over the longer term.

As mentioned in last quarter’s review, WTW made two methodology changes which has made UK equities relatively more attractive – this is notable considering its lower expected volatility, shown below, whereas the expected volatilities of other asset classes have increased.  During this quarter we took the opportunity to update our expense assumption for UK equities to incorporate UK stamp duty reserve tax (SDRT). SDRT is incurred when buying the underlying securities in UK equity funds (0.50% on purchases) and typically passed on via tools such as dilution levies.

The WTW and SDRT changes had largely offsetting impacts, which is why there is relatively low turnover across the portfolios.
