Why optionality matters more than optimisation right now

A THOUGHT that often crosses my mind is how the same mindset in different contexts can lead to staggeringly different results.

As a student, success usually involves learning what is in the curriculum and optimising performance within those clear boundaries.

In adult life, however, there is no single rule book or clear guide for success. Objectives are less clear; outcomes are harder to define. The world is simply more complex than before.

When you look at the markets through this lens, generally, optimism and the willingness to invest for the longer term in financial markets are key guiding forces. Long-term asset appreciation and the ability to hold through volatility work together synergistically.

But beneath this are also structural shifts in the assets driving returns over that time horizon.

For decades, portfolio optimisation has been based on expected returns, and finely tuned risk-return models have been the focus, grounded on the idea that markets are overall efficient and somewhat predictable. This is still a core of how we allocate investments today.

But I would argue that, right now, there is a strong case to value optionality more than pure optimisation.

Markets today are shaped by new asset classes, regime shifts and rapidly evolving technologies that disrupt established assumptions. Economic and market cycles are more unstable and shorter, requiring faster responses and greater flexibility.

Optimisation is, by definition, positioning for a base-case future. Optionality, by contrast, is about creating the ability to benefit from multiple possible futures.

Recent experience highlights why this matters. The sharp rise in interest rates in 2022, the tariff-related challenges of 2025, and the rapid emergence of artificial intelligence as a dominant investment theme all required investors to reassess and reposition quickly, often with limited information.

Leaving room for strategic adjustments

Optionality as a portfolio characteristic is not a new concept. The ability to invest in distressed or out-of-favour assets has long been viewed as a common investment style.

What deserves more attention today is the value of being able to pivot strategy as conditions change. If done well, this flexibility can mitigate downside risks by allowing positions to be exited, while also creating convexity, which is defined by the potential to benefit non-linearly if conditions shift again.

A purely optimised portfolio would typically utilise all available resources to target a single outcome. In doing so, it leaves little room for these strategic adjustments.

On the other hand, preserving capacity for optionality adds both insurance and opportunity to an otherwise stable portfolio designed to compound returns over time.

For ultra-high-net-worth families and family offices, this question has long been top of mind.

Investment horizons can span generations rather than years, making it inevitable that major structural shifts will occur. These challenges are often compounded by changes in operating businesses, evolving family dynamics and succession-planning considerations – all factors that cannot be addressed through a simple optimisation exercise.

At the same time, developments in financial markets have made it easier to build optionality into portfolios. Diversification is more accessible than ever, with a broader range of asset classes, markets and investment vehicles available to investors, from regular funds and exchange-traded funds to hedge funds and private assets.

Liquidity dynamics are also better understood following multiple shorter market cycles, allowing for more informed planning, particularly during times of stress. In addition, financial innovations have expanded the range of solutions that offer investors liquidity, each with its own trade-offs.

Taken together, these developments mean investors now have more ways to construct portfolios that retain flexibility, without having to remain in cash or cash-like holdings.

While holding cash remains the simplest and most immediately available source of optionality, it is not always the most efficient. Unless there is an urgent need to reposition, there is often an allocation window to deploy capital in a more laddered and measured way, reducing the long-term drag associated with cash.

Many liquid assets, or investments with liquidity features, are widely accessible now and can help strike a balance between maintaining a stable core allocation and retaining the ability to act on opportunities as they arise. Structural liquidity should not be confused with structural cash alone.

A place in long-term strategy

Each family and each portfolio is different, so broad generalisations should be avoided. But the core argument here is that optionality is a desirable feature of a consistent investment philosophy.

Where forecasts look less certain, optionality becomes more valuable. Where resilience matters more than precision, optionality prevails. Where your investment time horizon extends long enough for the world to change meaningfully, optionality prevails.

A common counterargument to this is that optionality may reduce returns in a bull market.

This may be true in the short term, but it is far less clear across full market cycles. I would compare this to the common sentiment on insurance: It often feels unnecessary when you are healthy, and its value is only apparent in hindsight. In that sense, underperformance in a bull market is a relatively good problem to have.

Another concern commonly flagged is that cash is a drag, lowering returns.

As noted earlier, this issue has become easier to address now that financial innovation has created more options to remain invested while preserving liquidity.

Building resilience in a portfolio today can therefore come at a relatively lower cost than in the past, particularly for investors who already have an existing well-diversified and finely tuned portfolio.

For investors navigating an increasingly complex world, where considerations extend beyond maximising returns alone, this is no longer something that can be ignored.

The tools to achieve this are more available than ever. Markets do not always reward the most accurate forecasts, but they tend to reward those who stay invested and are able to adapt as circumstances change.

Optionality is a structural factor in portfolio design that deserves a place in long-term strategy, even while we remain optimistic about future growth.

In doing so, we can continue to be like students, learning and adapting rather than assuming we know what tomorrow will bring.
