A Framework for Including Alternatives into a Portfolio

Over the years Kiwi Investor Blog has covered alternatives and the benefits they can bring to a well-diversified portfolio. What I have not done is provide a practical framework for how to actually introduce them.

This post attempts to do that. It is not a complete list. Think of it as a starting point.

A word on scope first. This is not an argument against equities and bonds. They will remain the core of most well-constructed portfolios and rightly so.

The case for alternatives is about enhancing those exposures, improving the overall risk and return profile of a portfolio, and building a portfolio that is more resilient across a range of different market environments.

The inclusion of alternatives is additive, not a replacement. Portfolio evolution, not revolution.

A Different Mindset Is Worth Considering

Successfully introducing alternatives into a portfolio is as much about mindset as it is about manager selection or asset allocation. The mindset question comes first.

A return-focused approach to investing, where the primary goal is maximising returns, beating a benchmark, or ranking well against peers, is a perfectly reasonable starting point for a traditional portfolio of equities and bonds. Returns are visible, measurable, and easy to communicate. There is nothing wrong with this orientation.

When it comes to including alternatives, a somewhat different way of thinking tends to be more useful. The investors who have most successfully built alternatives into their portfolios have generally approached the question from the perspective of risk and resilience first, with return as the outcome rather than the objective. The shift is subtle but it matters.

Rather than asking “how do we get more return?”, the question becomes “how do we build a portfolio that holds up well across a range of economic environments, and what role can alternatives play in that?” It is a different frame, and it opens up different possibilities.

This mindset is also consistent with maximising returns and ranking well against peers. Actually, it could be argued this mindset increases the probability of achieving these objectives.

This point is worth dwelling on, because it is subtle but important. Expected return is a single number, a central estimate of where a strategy might land on average. What an investor actually experiences, however, is just one outcome from a wide range of possibilities. A strategy with a higher expected return but a wide spread of potential outcomes may, in practice, have a lower probability of meeting a given return target than a strategy with a slightly lower expected return but a narrower spread.

Including alternatives can increase the probability of achieving an objective, even where the expected return of the portfolio is similar, or modestly lower. By reducing volatility around that expected return, alternatives can narrow the range of likely outcomes, which in turn lifts the probability of landing at or above whatever return is actually required. The goal shifts from maximising expected return to maximising the probability of achieving the return that is needed, a subtly different objective, but one that tends to align more closely with what investors are actually trying to do.

We will expand on this below, as alternatives have different roles to play in a well-diversified portfolio.

Anchoring to Goals and Outcomes Over the Cycle

This mindset shift is perhaps the most practical: moving from benchmark-relative thinking to goal-based thinking. Rather than measuring success against an index, the focus is on achieving clearly defined risk and return outcomes over the full market cycle. A market cycle is typically five to seven years.

The questions this raises are straightforward but important. What does the portfolio actually need to achieve? What income needs to be generated, and when? What level of drawdown is genuinely tolerable? What does success look like at the end of the investment horizon?

These questions are applicable for all investors, including KiwiSaver funds, those planning for retirement, charitable trusts, and ultra-high net worth individuals.

These different investors will have different answers. A charitable endowment might need to preserve real capital while distributing 4–5% per annum. A KiwiSaver member approaching retirement might prioritise avoiding a sharp drawdown in the final years before withdrawal. A family office might focus on inflation protection and multi-generational income. Each implies a different portfolio.

This longer-term, outcome-oriented framing is also what creates the right conditions for alternatives to be included. Once success is measured over a cycle rather than a quarter, the illiquidity of private markets becomes more of a feature than a constraint.

The investors who have thought carefully about their genuine liquidity needs, and found they can afford to look through short-term fluctuations, have generally been rewarded for it.

From Asset Allocation to Risk Allocation

A natural extension of this thinking is to consider not just how capital is allocated across asset classes, but how risk is allocated.

In a traditional 60/40 portfolio, roughly 90% of the portfolio’s volatility comes from equities, even though equities represent only 60% of the capital. The portfolio looks diversified on paper but is, in terms of risk, heavily concentrated. Making this visible is a useful exercise: it often motivates a genuine rethink of what diversification actually means in practice.

As I have written previously on this blog, true portfolio diversification does not come from investing in many different asset classes, it comes from investing in different risk factors. That is a foundation principle.

True diversification requires exposure to different risk factors. That is what alternatives, thoughtfully selected, can provide.

Designing for a Range of Environments

One of the most helpful ways to think about portfolio construction, and one that lends itself naturally to the inclusion of alternatives, is to design for uncertainty rather than optimise for a single forecast. Markets move in ways that surprise us. Economic conditions shift. What works well in one environment may struggle in another.

A useful starting point is to consider how a portfolio would perform across different economic conditions: periods of rising growth, falling growth, rising inflation, and falling inflation.

No single asset class does well in all four. Equities tend to thrive in rising growth and benign inflation. Bonds provide ballast in slowing growth and deflation. Real assets and inflation-linked securities come into their own when prices are rising.

A portfolio with some exposure across all of these environments is likely to be more resilient over time than one concentrated heavily in just one or two.

This way of thinking naturally leads to a broader set of portfolio building blocks, and alternatives, thoughtfully chosen, are part of that broader investment set.

Thinking About Downside, Not Just Upside

Another useful shift is to give more weight to downside protection. Returns compound, and losses interrupt compounding. A portfolio that falls 50% needs to gain 100% just to recover. Avoiding large drawdowns is not timidity; it is one of the more powerful tools available to long-term investors.

Thinking about the conditions under which a portfolio might suffer badly, and whether those risks have been adequately addressed, is a worthwhile complement to thinking about return potential. It does not mean avoiding risk. It means being deliberate about which risks are taken, and ensuring the portfolio is not unduly exposed to a single adverse scenario.

This framing also helps evaluate alternatives more clearly. A trend following strategy, for example, is often most useful not because it outperforms equities but because it tends to hold up, or even contribute positively, when equities are under stress. Evaluating alternatives on those terms, rather than purely against a return benchmark, tends to lead to better portfolio construction decisions.

A Framework for Thinking About Alternatives

Alternatives are not a monolith. Each category serves a different purpose within a portfolio, and understanding those purposes is critical to building a coherent strategy.

As Preqin have noted, investors’ motivations for investing in alternatives are quite distinctive. A useful way to think about this is through the lens of what each alternative brings to the table.

Private Equity — Access to companies and growth opportunities not available on public markets. The evidence for long-run outperformance over listed equities is well established, particularly among top-quartile managers. The trade-off is illiquidity and manager selection risk. Private equity rewards investors with long time horizons and the patience to stay the course.

Infrastructure (Unlisted) — Real, long-duration assets (e.g. toll roads, utilities, airports, renewable energy) that generate stable, predictable cash flows, often with inflation linkage. For portfolios with long-term income objectives, unlisted infrastructure is particularly compelling. It also tends to have lower correlation with listed markets, which is precisely the point.

Private Debt — Loans and credit instruments made outside the public bond markets. Private debt has grown substantially since the global financial crisis as banks retrenched from certain lending markets. It typically offers a meaningful yield premium over public credit in exchange for illiquidity, an attractive trade for investors who do not need immediate access to their capital.

Hedge Funds (and Alternative Risk Premia) — A broad category, but at their best, hedge fund strategies can provide genuine diversification: returns that are lowly correlated with both equities and bonds. Managed futures, global macro, and market-neutral strategies have historically performed well precisely when traditional portfolios have struggled. Not all hedge funds deliver on this promise. Manager selection and fee discipline matter enormously here.

The Attraction of Alternatives

Alternatives are generally added to portfolios for two primary reasons.

  • Enhance returns — for example, private equity and venture capital, where the objective is to access return premiums not available in public markets.
  • Diversification — for example, hedge funds and liquid alternatives, used to reduce portfolio declines at times of severe sharemarket falls.

Inflation hedging and yield enhancement are other reasons for allocating toward alternatives.

The motivations behind each allocation are quite distinctive. A Preqin survey of institutional investors found that investors’ reasons for holding different alternative asset classes vary considerably depending on the role each is expected to play in the portfolio. I covered this in more detail in Further growth expected for an Alternative future – Preqin.

The table below summarises the key findings.

Alternative Asset ClassPrimary Investor Motivations
Private Equity and Venture CapitalHigh absolute and risk-adjusted returns
Infrastructure and Real EstateAn inflation hedge and a reliable income stream
Private DebtHigh risk-adjusted returns and an income stream
Hedge FundsDiversification and low correlation with other asset classes
Natural ResourcesDiversification and low correlation with other asset classes
Insurance-Linked SecuritiesIncome and diversification

What stands out from this table is that no single alternative is being held for the same reason. Some are held for return enhancement, some for income, some for inflation protection, and some purely for diversification. This reinforces the broader point made: alternatives are not a single decision but a set of distinct building blocks, each chosen for a specific role within the overall portfolio.

Consistent with the above commentary, the following graph presents the rationale for investing in alternatives based on the CAIA Members surveyed in 2020.

Practical Considerations: Liquidity, Fees, and Manager Selection

Moving into alternatives is not without complexity. Three issues deserve careful consideration.

Liquidity is the most important starting point. Before allocating to illiquid strategies, investors should rigorously assess their true liquidity needs, not their perceived needs, but their actual cash flow requirements over a 5–10 year horizon. Liquidity should be treated as a budget: deploy it wisely.

Fees in alternatives are higher than in traditional asset classes, and that is a legitimate consideration. But higher fees are not automatically a problem. What matters is the return after fees. A private equity fund that delivers 4–5% above public equity returns net of all costs is clearly worthwhile. Every alternative should be assessed on its after-fee contribution to the portfolio. For a more detailed discussion on fees and alternatives, please see my previous post Investment Fees and Investing like an Endowment – Part 2.

Manager selection matters far more in alternatives than in listed markets. The spread between top-quartile and bottom-quartile private equity managers, for example, is enormous, far greater than the equivalent spread in traditional asset classes. Gaining access to top-tier managers is both critical and, for many smaller investors, genuinely challenging. Although fund-of-funds structures, co-investment platforms, and specialist advisers can all play a role here, the layering of fees and risk exposures is important, e.g. the liquidity framework.

Where to Start

For investors new to alternatives, a phased approach is sensible. A reasonable starting point for a medium-to-long-term investor might include the following:

  • Set a target allocation of 10–15% as an initial ambition, with the intention to build over time as governance capability and manager relationships develop.
  • Start with the most accessible categories. Unlisted infrastructure, private equity, and private debt tend to be more straightforward entry points than hedge funds. They are also easier to explain to stakeholders.
  • Build governance capability first. Alternatives require more active oversight, deeper due diligence, and clearer investment policy frameworks than listed strategies.
  • Commit across vintages. Private markets operate on multi-year cycles. Spreading commitments across different vintage years reduces timing risk significantly.

Pulling It Together

The argument here is not that equities and bonds should be abandoned, far from it. They remain the foundation of a well-constructed portfolio.

The argument is that a portfolio composed only of equities and bonds is leaving risk-adjusted return potential on the table, and accepting a concentration of risk that long-term investors can afford to reduce.

The mindset shift comes first: from a focus on return to one of risk management and resilience, from benchmark-beating to goal achievement, from optimising for one environment to building a portfolio that can perform across many. The framework for alternatives follows naturally from that shift.

The world’s best long-term investors understood this a long time ago. The opportunity for New Zealand investors, whether managing KiwiSaver assets, endowment funds, or family wealth, is to apply the same thinking here. The evidence is clear. The framework exists.

Welcome Back — and Welcome

This Is What Kiwi Investor Blog Is About.

Ten essential posts. The ideas that define this blog. A guide for new readers and a reminder for those who have been here before.

After five years away, this post reintroduces Kiwi Investor Blog: what it is, what it is trying to do, and where to start if you are new. Rather than simply listing posts, it curates ten of the blog’s most read and enduring pieces and explains, for each one, why the idea matters, what it challenges, and what a thoughtful investor should take away from it. If you have been here before, think of this as a reset. If you are new, think of it as a guided introduction to a set of ideas that most mainstream New Zealand financial commentary does not cover.

What Kiwi Investor Blog is — and what it is trying to do

Kiwi Investor Blog started from a simple observation: there is a gap between how the world’s best institutional investors think about building and managing investment portfolios, and what is available to most New Zealand investors in the way of independent commentary, research, and analysis.

The large global pension funds, endowments, sovereign wealth funds and insurance companies that manage hundreds of billions of dollars collectively have access to world-class research, sophisticated portfolio construction frameworks, and decades of accumulated experience in areas that barely feature in mainstream New Zealand investment conversation.

This blog’s purpose is to close that gap. Not by dumbing ideas down, but by translating concepts, frameworks, and research that institutional investors use routinely and making them accessible, relevant, and practically useful for a wider New Zealand audience.

The topics that most NZ financial commentary doesn’t cover — and why they matter

Mainstream personal finance commentary in New Zealand is overwhelmingly focused on a narrow set of topics: KiwiSaver fund selection, property versus shares, mortgage strategy, and the basics of budgeting. These are all very worthwhile subjects and covered well. But they represent a small fraction of the investment landscape that a thoughtful investor needs to navigate.

Kiwi Investor Blog has, since its inception, focused on topics that are discussed in institutional investment circles but are largely absent from the broader NZ investment conversation:

  • Behavioural finance — the systematic ways in which investor psychology undermines investment outcomes, and how to design against it.
  • True diversification — what it actually means to hold a portfolio whose components behave differently from each other, and why most ‘diversified’ funds are less diversified than they appear.
  • Alternative investments — the role of hedge funds, private equity, real assets, and liquid alternatives in building more robust portfolios, and why New Zealand investors have historically had limited access to them.
  • Liability-driven investing — the framework used by insurance companies and some pension funds to match assets to income needs, applied to the challenges facing individual NZ investors approaching and in retirement.
  • The limitations of the balanced fund — why the standard 60/40 portfolio carries more risk than investors fully appreciate, and what more robust alternatives look like.
  • Fees and their compounding effect — why even small fee differences are large in the long run, and how to read an investment fee disclosure with clear eyes.

None of these topics is especially complex. But none of them gets the sustained, rigorous treatment in NZ financial media that they deserve. That is the gap this blog exists to fill.

Ten essential posts — a guided tour of the blog’s core ideas

The following posts are selected from the blog’s archive based on two criteria: enduring relevance (the ideas are as important today as when they were written) and distinctive value (the content covers ground that is not widely available elsewhere in the NZ investment commentary landscape). They are presented with a summary of the key argument and the single most important insight for a reader to take away.

Post 1  ·  BEHAVIOURAL FINANCE

1. The Benefits of Behavioural Finance in the Investment Planning Process

Why do smart, well-informed investors consistently make the same predictable mistakes? Behavioural finance is the field that answers that question by drawing on psychology and economics to explain why human beings are systematically poor at managing money, even when they know better. This post introduces the key concepts of loss aversion, overconfidence, herding, and recency bias and explains how awareness of these tendencies can be built into the investment planning process itself. It remains the most-read post in the blog’s history for good reason: the insights are universal, timeless, and directly actionable.

Key insight:  Knowing that markets are irrational is useless if your own behaviour is equally irrational. The goal of behavioural finance is not just to understand markets but to also understand yourself as an investor.

2. A Short History of Portfolio Diversification

Diversification is the only free lunch in investing. That phrase is used so often it has lost its meaning. This post traces the intellectual history of diversification from Harry Markowitz’s 1952 mean-variance framework through to modern multi-asset portfolio construction, explaining not just what diversification means but why it works, when it doesn’t, and what institutional investors have learned about it over seven decades of practice. It is a foundational piece for any serious investor.

Key insight:  True diversification is not about holding many assets. It is about holding assets whose returns are driven by genuinely different economic forces. A portfolio of 20 funds all exposed to the same equity risk premium is not diversified.

3. Disaggregation of Investment Returns

One of the most practically useful posts on the blog — and one of the most underappreciated. Most investors think of their portfolio return as a single number. This post explains how that return can be decomposed into its component parts: the market beta, the factor exposures, the manager skill (alpha), and the fees extracted at each layer. Understanding which part of your return is coming from where is the foundation of intelligent portfolio evaluation. It is a concept that institutional investors use routinely and that is almost entirely absent from retail investment commentary in New Zealand.

Key insight:  Before you can assess whether your investment manager is adding value, you need to understand what portion of their return you are already paying for through passive exposure and what, if anything, is left over after fees.

4. The Traditional Diversified Fund Is Outdated — Greater Customisation Is Required

The one-size-fits-all balanced fund has been the default vehicle for New Zealand investors for decades. In most cases this suits investors well. This post makes the case for greater portfolio customisation to reflect the investor’s specific risk tolerances, time horizons, liability profiles, and income objectives. The argument draws on how large institutional investors such as pension funds, endowments, and sovereign wealth funds think about portfolio construction, and asks why individual investors are routinely offered something less sophisticated.

Key insight:  The institution managing a $10 billion pension fund does not use a balanced fund. It builds a portfolio around the specific liabilities it needs to meet. Sophisticated individual investors have specific financial goals too, and their portfolios should reflect them.

5. The Psychology of Portfolio Diversification

A companion piece to the behavioural finance post, focused specifically on how psychological biases affect the way investors think about and implement diversification. Home bias, the tendency to overweight familiar domestic assets, familiarity bias, mental accounting, and the illusion of diversification (holding many funds that are all highly correlated) are explored in detail. The post bridges theory and practice in a way that is immediately useful for investors reviewing their own portfolios.

Key insight:  New Zealand represents less than 0.2% of global equity market capitalisation. A portfolio that over-invested in NZ assets is not diversified; it is a concentrated bet on a single small economy.

Post 6  ·  FEES & COSTS

6. Five Myths About Investment Management Fees — Broadening the Fee Debate

Fees are the single most controllable variable in long-term investment outcomes, yet they are consistently misunderstood, underestimated, and obscured by the investment industry. This post takes on five of the most persistent myths about investment management fees, including the idea that higher fees reflect higher quality, that fee differences of less than 1% are immaterial, and that all fees are disclosed in a way that allows meaningful comparison. It is a post that will save most readers money simply by changing how they read a fund disclosure document.

Key insight:  A fee difference of 0.5% per annum appears small. Over 30 years of compounding on a $200,000 portfolio, it is worth approximately $85,000 in foregone wealth. Fees compound in exactly the same way as returns, but in reverse.

Post 7  ·  RISK & PORTFOLIO THEORY

7. Understanding the Impact of Volatility on Your Portfolio

Volatility is the most widely cited measure of investment risk and one of the most widely misunderstood. This post explains not just what volatility means statistically, but why the path of returns matters as much as their average level, a concept with profound implications for retirement investors in particular. The mathematics of volatility drag, the asymmetry between gains and losses, and the practical consequences for portfolio construction are all covered in a way that builds genuine intuition rather than just presenting formulas.

Key insight:  A portfolio that falls 50% needs to rise 100% to recover. This asymmetry, not widely appreciated by investors, is why managing downside risk is not the same as being conservative. It is the foundation of intelligent risk management.

8. Time to Move Away from the Balanced Portfolio — They Are Riskier Than You Think

Written before the events of 2022 made its argument unavoidable, this post explains why the traditional 60/40 balanced fund carries more risk than investors typically appreciate. The equity risk dominance of the balanced portfolio and the fact that in almost any significant market downturn, the balanced fund falls alongside equities is laid out clearly. The conditions under which bonds genuinely diversify equity risk are examined, along with the circumstances in which that diversification fails. Events since 2022 have provided a live demonstration of precisely the argument this post made.

Key insight:  In 49 of the last 50 years, when the US equity market fell, a 60/40 balanced portfolio also fell. The 40% in bonds has provided partial cushioning, but it has never been a genuine alternative to equity risk management.

Post 9  ·  BEHAVIOURAL FINANCE

9. The Regret-Proof Portfolio

One of the most distinctive posts on the blog and one that addresses a dimension of investing that almost no one in the industry discusses seriously. Regret is a powerful emotion in investment decision-making: the regret of having sold before a rally, of having stayed in a falling market, of having chosen the wrong fund. This post proposes a framework for thinking about portfolio construction that accounts for the investor’s own emotional responses not to indulge them, but to design a portfolio the investor can actually stick with through market cycles. A portfolio that is technically optimal but behaviourally unsustainable is not actually optimal.

Key insight:  The best investment strategy is not the one with the highest expected return. It is the one you will actually implement, hold through downturns, and not abandon at the worst possible moment. Regret minimisation is a legitimate and underused design principle.

Post 10  ·  RETIREMENT INCOME

10. More on Liability Driven Investing (LDI) for Beginners

Liability-driven investing is the framework that the world’s largest insurance companies and pension funds use to manage the challenge of converting an asset pool into a reliable income stream. In New Zealand, it is almost entirely absent from the mainstream conversation about retirement planning. LDI is directly applicable to the situation facing every KiwiSaver member approaching retirement. This post introduces the core concept in plain English: rather than asking ‘how do I maximise returns?’, LDI asks ‘what income do I need, when do I need it, and how do I build a portfolio that reliably delivers it?’ It is the intellectual foundation for this blog’s approach to retirement income, and remains as relevant today as when it was written.

Key insight:  Every investor approaching retirement has liabilities: the income they will need each year to fund their lifestyle. LDI matches assets to those liabilities explicitly. It is not exotic or complex. It is simply asking the right question first.

Further posts are planned across the blog’s core topics of behavioural finance, portfolio construction, alternatives, and retirement income.

A note to returning readers

If you subscribed to this blog before 2021 and found your way back: thank you. A lot has happened in markets over the past five years that this blog warned about, and a lot has changed that is worth examining together. The core thesis of this blog has not changed: that institutional-quality thinking, made accessible and applied honestly to the NZ investment landscape, is genuinely valuable to all investors. If anything, the events of 2022–2026 have reinforced rather than undermined that view.

If you are new: welcome. Start anywhere on the list above. The posts are independent of each other and do not require prior knowledge of the blog. What they do require is a willingness to engage with investment ideas, to question conventional wisdom, to think in frameworks rather than rules of thumb, and to accept that good investment thinking is demanding but not inaccessible.

The gap between how institutional investors think about this and what most New Zealanders have access to is real. This blog’s aim is to narrow it, one post at a time.
