Portfolio asset allocation and
trends within UK advisers’
portfolios in 2020

 Portfolio asset allocation and trends within UK advisers’ portfolios in 2020

By Joshua Woodruff, head of portfolio analytics and consulting, and Monika Dutt, portfolio consultant

Have you ever wondered why your portfolio is not performing quite as you had expected? Vanguard has conducted an in-depth analysis to help advisers understand more about the portfolio inefficiencies that could be costing them and their clients valuable returns.

We lifted the bonnet on 91 balanced1 portfolios sent to us by our UK clients between January and November this year. Our aim was to shine a light on their true positioning and the potential impact of unintended gaps, biases and concentrations versus the benchmark2. The resultant analysis revealed hidden trends that may come as a surprise to advisers.

The main structural change we found was that UK advisers had moved away from the 60% equity - 40% fixed income split of a classic balanced portfolio. While equity exposure remained stable, we observed that advisers allocated around a quarter of their fixed income holdings to non-traditional assets such as commodities, direct property and private equity.

In our view, while non-traditional asset classes can introduce diversification benefits, they can also increase costs, lower transparency and reduce liquidity. Furthermore, non-traditional assets delivered a wide range of outcomes, as evidenced by the 25% rally in gold and the 43% fall in oil in the ten months to the end of October3.

Looking at equities, one of the most striking findings was the broad underweighting of US stocks. On average, US equities represented only about 34% of advisers’ portfolios in our study, significantly lower than their average weight of approximately 56% in the global equity market during 20204. This underweighting held back portfolio returns, with the US equity market outperforming global stocks by approximately 5 percentage points from January to October5.

The advisers’ portfolios we examined also had a significant home bias, with an average allocation of approximately 30% towards UK stocks versus a global weighting6 of just 4.4%. Over the period we reviewed, this positioning will have weighed markedly on performance as the FTSE All-Share Index trailed the global average by approximately 24 percentage points7.

However, favouring the home market is often a conscious asset-allocation decision for reasons of familiarity and reduced currency risk. Therefore, a period of underperformance may not be a reason to change the underlying portfolio construction as long as it is still consistent with client objectives.

Our analysis also suggests that regional equity exposures can drive unintended sector positioning and influence returns unexpectedly. We saw, for instance, that a broad underweighting to US equities may have resulted in a lower relative exposure to technology, the best-performing sector over the observed period8.

Equity country and sector tilts can also influence a portfolio’s style biases. Our study found that advisers’ portfolios were underweight to large-cap growth stocks. This appeared to be less of an intentional shift, and more of a consequence of the low relative holdings in big US tech stocks. Once again, we saw how a regional preference can risk unbalancing exposures elsewhere in the portfolio.

Within fixed income we observed a number of trends. The main theme was a reduced government-bond exposure in favour of corporate bonds. Against low yields in government-bond markets, the attractions of corporate debt have risen following their inclusion in expanded central bank asset-purchase schemes. But advisers reducing exposure to government bonds may risk losing the valuable capital-preservation advantages of the asset class when sentiment collapses.

Different asset types, markets, sectors, styles and capitalisation groups will inevitably experience periods of under- and outperformance over time. Indeed, our trends study shows that at times of market dislocation, such as the current Covid-19 crisis, portfolios’ vulnerability to inefficiencies in their asset allocation can become more explicit.

To help ensure valuable performance is not needlessly sacrificed at times of heightened uncertainty, we caution clients to focus on long-term expected returns, adopt a diversified approach to asset allocation and avoid the temptation of trying to time such tumultuous markets.
