How to Rebalance Your Portfolio After 3 Years of Bull Markets

A portfolio that began 2022 with 60% allocated to equities has, through three years of compounding gains, likely drifted to 70% or beyond. No decision was made. No trade was placed. Yet the investor now carries meaningfully more equity risk than they intended, and meaningfully more exposure to a correction they have not planned for.

The post-2022 bull market, which saw individual stocks like Nvidia surge approximately 1,476% from their November 2022 trough and the S&P/ASX 200 close above 8,600 in early May 2026, has silently restructured the risk profile of portfolios left unattended. This is not an issue confined to aggressive traders. It is a structural condition affecting a broad range of Australian investors, from self-managed super fund (SMSF) trustees to set-and-forget industry fund members.

This guide walks through how to recognise allocation drift in a portfolio, when the right moment to act is, what rebalancing options are available inside Australian tax structures, and where reallocated capital can go, including fixed income, private credit, and market-neutral strategies.

Why three years of equity gains have quietly changed your risk profile

Allocation drift is a passive phenomenon. When equities outperform other asset classes over an extended period, they grow as a share of the total portfolio without any investor action. The result is a portfolio that carries more potential upside, but also more downside exposure, than the investor originally intended.

The scale of that drift since 2022 has been substantial. Consider how far the largest global equities have travelled from their November 2022 trough:

• Nvidia: approximately 1,476%
• Meta: approximately 613%
• Alphabet: approximately 269%
• Amazon: approximately 177%
• Microsoft: approximately 122%
• Apple: approximately 115%

Australian investors with even modest international equity exposure, whether held directly or through managed funds and exchange-traded funds, have absorbed some of this appreciation into their portfolios.

An investor who held a 60/40 equity-to-defensive split at the start of 2022 could, without placing a single trade, now hold closer to 70/30. That ten-percentage-point shift is not a rounding error. It represents a structurally different risk profile.

The S&P/ASX 200 closed at 8,697.10 on 4 May 2026, reflecting sustained elevation despite a sell-off in March 2026. For investors who have not reviewed their asset allocation since 2022 or 2023, the portfolio they hold today may bear little resemblance to the one they designed.

What portfolio rebalancing actually means and why it works

Rebalancing is the process of selling portions of outperforming assets and redirecting that capital to underperforming or underweight asset classes, restoring the portfolio to its target allocation. It sounds simple. The difficulty is psychological.

The discipline at the core of rebalancing is counterintuitive: it requires trimming the assets that have performed best. In a portfolio where equities have surged, rebalancing means selling some of those winners and buying into asset classes that have lagged. This feels uncomfortable. It also enforces a systematic sell-high, buy-low logic that, over time, reduces the portfolio’s vulnerability to sharp corrections in any single asset class.

Calendar-based versus threshold-based triggers

Two primary methodologies determine when to rebalance:

1. Calendar-based rebalancing: Reviews are scheduled at fixed intervals, typically annually or semi-annually, regardless of what markets have done in between. This approach removes timing anxiety and ensures the portfolio is assessed at regular intervals. Annual or semi-annual reviews remain the professional standard confirmed by practitioner consensus in 2026.
2. Threshold-based rebalancing: Action is triggered when any single allocation drifts more than a predetermined band, commonly 5%, above or below its target. This method responds to market conditions rather than the calendar, catching large moves that occur between scheduled reviews.

Most Australian advisers recommend using both in combination. The calendar review provides structure; the threshold check serves as an early-warning mechanism between scheduled reviews. The March 2026 ASX sell-off, for example, was the kind of volatility event that would have triggered a threshold-based review for investors whose equity allocation had already drifted above target, creating an opportunistic window to rebalance while equities were temporarily cheaper.

How Australian tax structures change the rebalancing calculus

Understanding the mechanics of rebalancing is one step. Executing it efficiently inside the Australian tax system is another, and the difference between account types can be worth thousands of dollars.

Rebalancing inside a superannuation or SMSF structure avoids immediate capital gains tax (CGT) at the investor’s marginal rate. Earnings within the fund are taxed at the concessional rate of 15%, making the cost of selling appreciated equity positions substantially lower than in a taxable account. For investors whose super balance represents a significant portion of their total wealth, this is the most efficient vehicle for executing rebalancing trades.

The efficiency advantage of rebalancing inside superannuation is real, but it co-exists with structural costs embedded in fund architecture, including CGT drag from member exits, indirect cost ratios, and swap-based index financing spreads, that never appear as line items on a member’s annual statement.

For taxable account holders, the calculus is different. Selling long-held appreciated equity positions triggers CGT. However, the 50% CGT discount available to Australian individuals and trusts for assets held more than 12 months reduces the effective tax cost. An alternative approach, one that avoids triggering CGT entirely, is to direct new contributions or dividend income toward underweight asset classes rather than selling overweight positions. This is slower but lower-friction.

For investors in taxable accounts where selling appreciated positions would trigger CGT, directing new contributions to underweight assets over a structured period functions as a lower-friction rebalancing mechanism, one that also creates multiple CGT parcels with distinct acquisition dates, adding flexibility to future disposal decisions.

The interest rate environment adds a further dimension. With the RBA cash rate expected at 4.35% as of 5 May 2026, fixed income has returned as a genuinely competitive yield destination. Bonds and term deposits now offer returns that make them a meaningful rebalancing target, a significant shift from the 2020-2022 low-rate environment when defensive assets offered negligible income.

Where to put the capital you trim from equities

The question that follows any rebalancing decision is immediate: where does the freed capital go? For Australian investors in 2026, the range of viable destinations is broader than it has been in years.

Fixed income and cash are the most straightforward options. After years of near-zero returns, bonds and term deposits now offer competitive yields supported by the 4.35% RBA cash rate environment. For investors whose defensive allocation has fallen below target, simply topping up fixed-income holdings restores balance while generating meaningful income.

Domestic fixed income yields have repriced substantially alongside the RBA tightening cycle, with the Australia 10-year government bond yield reaching 5.02% in April 2026, a level that makes duration-conscious bond allocations a more meaningful rebalancing destination than at any point since the pre-2020 rate environment.

Private credit and market-neutral funds as rebalancing destinations

Private credit has emerged as a rebalancing destination that sits between traditional fixed income and listed equities. Australia’s private credit market has matured significantly, with some products now accessible to retail investors at minimums as low as $2,000. Targeted returns of approximately 6-9% per annum, with monthly income distributions, position these products as income-generating alternatives that do not carry listed equity beta.

Evaluating private credit products requires discipline. Four criteria warrant attention:

• No concentration in property developer loans
• Short average loan duration
• At least monthly liquidity provisions
• No lock-up periods

ASIC’s 2026 key issues outlook identifies product design and disclosure in private credit as a primary area of regulatory concern. Retail investors should review product disclosure statements carefully before committing capital to any private credit fund.

ASIC’s key issues outlook for 2026 identifies product design and disclosure in private credit as a primary regulatory concern, with the regulator specifically focused on risks of unsuitable product selection and inadequate disclosure for retail investors accessing private market products through managed investment schemes.

Market-neutral arbitrage funds represent a second alternative. These strategies are designed to generate returns with minimal or no correlation to listed equity markets, making them structurally useful in a rebalanced portfolio. A documented track record of double-digit returns is a relevant selection criterion when assessing these funds.

For context, major Australian super funds held approximately 59% in equities as of late 2025, with funds such as AustralianSuper targeting 10-15% in private equity allocations. The institutional trend toward diversification beyond listed markets is directionally consistent with the rebalancing logic available to individual investors, though the specific products and access points differ.

Establishing a sustainable rebalancing plan

A rebalancing strategy only produces results if it is executed. The most common failure is not misunderstanding the mechanics; it is delay. Investors who understand the logic of trimming equities during a bull market frequently postpone the decision because it feels like leaving gains on the table.

The 2026 context provides a useful counter to that hesitation. Elevated valuations, stretched pricing in AI-related sectors, and the March 2026 sell-off serve as reminders that markets do not move in straight lines. Investors who had pre-specified their trigger thresholds before March were positioned to act with clarity rather than uncertainty.

Three steps build a discipline that holds:

1. Document target allocations: Write a brief investment policy statement specifying the target percentage for each asset class. This creates an external commitment that reduces the behavioural temptation to let winning positions run indefinitely.
2. Set trigger thresholds: Define the drift percentage (commonly 5%) that will prompt a review, regardless of what the calendar says.
3. Schedule a fixed review date: Choose an annual or semi-annual date for a full portfolio assessment, and treat it as non-negotiable.

Institutional commentary from Invesco Australia, State Street Global Advisors, and Vanguard Australia in 2026 directionally favours cyclical and yield-oriented repositioning, alongside a reduction in mega-cap concentration risk. The professional consensus supports the logic of trimming equity overweights created by the post-2022 rally.

The cost of waiting is higher than most investors assume

Three years of equity outperformance have silently shifted the risk architecture of many Australian portfolios. The longer that drift persists, the more exposed investors are to a correction that returns valuations toward historical norms.

The practical pathway is clear: assess current allocations against target, use super or SMSF structures where possible to minimise tax friction, evaluate fixed income and selective alternatives such as private credit and market-neutral funds as capital destinations, and commit to a documented trigger-based or calendar-based review discipline.

Rebalancing in 2026 is not about predicting a correction. It is about ensuring the portfolio an investor holds today still reflects the risk they intended to carry, rather than the risk the last three years of markets silently assigned to them.

The first step is straightforward. Pull a current allocation statement, compare it against the target, and measure the gap. For investors who need guidance on tax-efficient execution, consulting a FAAA-member financial adviser can help translate intent into action.
