Strategic Asset Allocation for High-Balance Super Accounts: Building Resilience in Uncertain Times
When your superannuation balance exceeds $500,000, the conversation around asset allocation shifts from simple growth-focused strategies to more nuanced approaches that balance wealth preservation with continued accumulation. This threshold represents a pivotal point where sophisticated planning can deliver substantial benefits, and where mistakes become significantly more costly.
The Foundation: Understanding Modern Portfolio Theory
Despite being developed decades ago, Modern Portfolio Theory remains relevant for high-balance super members. The core principle—that diversification allows you to reduce risk without proportionally reducing expected returns—becomes increasingly valuable as your balance grows. However, the practical application has evolved considerably.
Traditional asset allocation models relied heavily on the historical negative correlation between stocks and bonds. During market stress, bonds would typically rise as stocks fell, providing portfolio stability. Recent years have challenged this relationship, with periods where both asset classes declined simultaneously due to inflation concerns and central bank policy responses.
This breakdown of traditional diversification relationships means high-balance members must think more creatively about building resilient portfolios. The goal is constructing an asset allocation that can perform reasonably across multiple potential economic scenarios rather than optimising for a single expected outcome.
Beyond the Standard Options
Most retail super funds offer a tiered selection of investment options, typically ranging from "Cash" and "Conservative" through to "High Growth" or "Aggressive." While these pre-mixed options provide convenience and automatic rebalancing, members with substantial balances should carefully evaluate whether these standard allocations truly serve their interests.
Lifecycle or Target Date Funds: These automatically adjust from growth-oriented to conservative as you age. While conceptually appealing, they make broad assumptions about your circumstances that may not apply. Someone with substantial savings outside super, ongoing employment income, or defined benefit entitlements might rationally maintain higher growth allocations later in life than these funds provide.
Balanced Options: The traditional "Balanced" option, typically holding 60-70% growth assets, has been the default for many Australians. However, this allocation may be either too conservative for younger members with long time horizons or too aggressive for those approaching retirement with substantial balances they cannot afford to see significantly diminished.
High-balance members should consider whether their fund offers the ability to build custom portfolios by directly allocating across individual asset classes. This approach requires more engagement but allows precise tailoring to personal circumstances.
The Growth Asset Allocation Decision
Within growth assets, the split between Australian and international equities deserves careful consideration. Many Australians maintain a home-country bias, with allocations to Australian shares far exceeding our roughly 2% share of global market capitalisation.
Australian Equities: The ASX provides good exposure to financial services, resources, and increasingly, healthcare companies. Australian shares offer franking credits—tax benefits on dividend income that can be particularly valuable in the pension phase. However, the Australian market lacks significant exposure to technology giants and innovative growth companies that dominate global indices.
International Equities: Accessing global markets provides exposure to sectors and companies unavailable domestically. The US market alone offers access to the world's leading technology, pharmaceutical, and consumer companies. European and Asian markets provide further diversification benefits. However, currency fluctuations add an additional layer of volatility that must be managed.
Currency Hedging: For high-balance members, the decision whether to hedge international currency exposure becomes significant. Hedging costs money and reduces potential gains when the Australian dollar weakens, but provides protection when it strengthens. Many sophisticated investors maintain a partially hedged position, gaining some currency diversification benefits while limiting extreme outcomes.
The Defensive Allocation: Beyond Simple Bonds
The defensive portion of a portfolio traditionally consisted of cash and fixed income, but today's environment demands more sophistication.
Cash and Term Deposits: While providing stability and liquidity, cash holdings erode in real terms during inflationary periods. However, maintaining some cash allocation provides dry powder for opportunistic investment during market dislocations.
Government Bonds: Australian government bonds remain effectively risk-free from a credit perspective but have experienced significant volatility as interest rates have moved. Long-dated bonds are particularly sensitive to rate changes. For defensive allocations, shorter-duration bonds provide more stability.
Corporate Bonds: Higher-quality corporate bonds offer yield premiums over government securities. However, during market stress, corporate bonds can decline alongside equities as credit spreads widen, reducing their defensive portfolio role.
Inflation-Linked Bonds: These securities provide protection against unexpected inflation, adjusting both principal and income payments based on the consumer price index. For retirees drawing regular income, this inflation protection has substantial value.
Alternative Investments and Real Assets
With balances exceeding $500,000, members should investigate whether their fund provides access to alternative investment classes that can enhance portfolio resilience.
Listed Property and Infrastructure: REITs and infrastructure securities provide exposure to real assets with the liquidity of listed markets. These investments often generate steady income streams and offer some inflation protection as rents and user charges typically rise with general price levels.
Unlisted Property and Infrastructure: Direct holdings in shopping centers, office buildings, toll roads, or airports can provide enhanced returns compared to listed equivalents, though they come with reduced liquidity and higher fees. For long-term super investors not needing immediate access to capital, this liquidity sacrifice may be acceptable for higher expected returns.
Private Equity: Some industry funds and platforms offer access to private equity investments. These can deliver superior long-term returns but require patient capital and come with vintage year risk—the specific timing of investment significantly impacts outcomes.
Rebalancing Discipline
With larger balances, the dollar amounts by which your portfolio drifts from target allocations become more substantial. A 5% drift in asset allocation on a $500,000 portfolio represents $25,000—enough to warrant attention and action.
Systematic rebalancing forces you to "sell high and buy low," trimming positions that have performed well and adding to those that have underperformed. This contrarian discipline is psychologically difficult but mathematically beneficial over time.
However, tax considerations complicate rebalancing in super. Capital gains tax applies to assets in accumulation phase, making frequent trading potentially costly. In pension phase, with no tax on investment earnings, rebalancing becomes tax-free, providing greater flexibility.
Sector and Factor Considerations
Beyond broad asset class allocation, high-balance members should consider sector exposures and factor tilts within their equity allocations.
Traditional sector classification distinguishes between defensive sectors (healthcare, utilities, consumer staples) and cyclical sectors (financials, materials, industrials). Technology now defies easy categorization, containing both high-growth speculative companies and stable, cash-generative giants.
Factor-based investing attempts to capture systematic sources of return beyond broad market exposure. The most researched factors include:
Value: Companies trading below their fundamental value
Momentum: Companies with strong recent performance
Quality: Companies with strong profitability and balance sheets
Low Volatility: Companies with more stable price histories
Size: Small-cap companies historically outperforming large-caps
While factor investing has academic support, implementation matters significantly. Factor performance is cyclical, with extended periods of underperformance testing investor patience. For high-balance members, modest factor tilts can enhance diversification without dramatic strategy shifts.
The Income vs Growth Question
Members approaching or in retirement often shift focus from wealth accumulation to income generation. However, the distinction between income and growth is more semantic than substantive from a total return perspective.
A company paying 4% dividends that doesn't grow is economically equivalent to a non-dividend paying company whose shares appreciate 4% annually, yet behavioral psychology means investors treat them very differently. High-balance members should focus on total return—the combination of income and capital growth—rather than fetishising yield.
That said, reliable income streams provide psychological comfort and reduce the need to sell assets during market downturns. For retirees drawing pensions, constructing portfolios that generate sufficient income to minimize forced selling during bear markets represents sound risk management.
Monitoring and Adjustment
Investment strategy should not be "set and forget." Market conditions evolve, personal circumstances change, and new opportunities emerge. High-balance members should review their asset allocation at least annually, considering:
Has your risk tolerance changed based on age or circumstances?
Have any asset classes become significantly over or undervalued?
Has market volatility changed your sleep-at-night comfort level?
Do legislative or tax changes warrant strategic adjustments?
The goal is remaining appropriately dynamic without falling into the trap of constant tinkering that generates unnecessary costs and taxes while failing to add value. Finding this balance between engagement and patience marks the difference between successful and mediocre long-term investment outcomes.
