Five risks for 2026

2025 has so far been a solid year for equity and fixed income returns. Despite a range of economic and policy uncertainties, investors have been willing to pay more for earnings in the US, resulting in a push higher in equity valuations. 

Policy rate expectations have moved lower in the US and Australia, helping bonds rally and credit spreads tighten. As we approach 2026, it makes sense to take stock of the risks for investors, both to the upside and the downside. In this note, highlight five key risks for 2026, and make some comments on the implications for investor portfolios. 

Risk 1: Returns revert to historic averages

Equity markets have ripped higher in the past 5 years, with double digit average total returns becoming the norm. The average total return in the US has approached 20%. In Australia, it is close to 15%.

These returns are unusual relative to history. Chart 1 shows something closer to 10% and 8% in the US and Australia respectively, over a 20-year period.

Chart 1: Average returns have been very strong over the past 5 years.

Valuations are now very stretched relative to history. Chart 2 shows a longer-run average, with both the US and Australia equity market sitting well above these averages.

Chart 2: Stretched valuations relative to history have not been good for forward looking returns.

Stretched valuations have historically coincided with weak forward-looking returns. It is important to note this does not mean negative returns. But we characterize these markets as having potentially had returns dragged from the future.

For investors, there are two key implications. First, investors may need to prepare for lower returns than they have experienced over the past five years. This could feel bad, even though the absolute return could be ok.

And second, it makes sense to carefully consider allocations to equities, especially if allocations have built up over the ripping bull market of the past five years. 

Risk 2: Australia outperforms the US

Australian equities have been a material underperformer relative to US equities over the past decade. Many of the reasons are well documented – the rise of technology and more recently, AI, US economic exceptionalism, structural slowdown in China weighing on Australia, among others.

Chart 3: US equities have delivered strong returns to investors over the past 10 years.

But this US outperformance has not always been a feature of global markets. The first part of this century saw Australia ride a mining construction boom to material outperformance. Australia truly was a lucky country, avoiding recession and experiencing significant financial inflows into its domestic markets.

Chart 4: A wider lens shows Australian equities have been a strong performer this century.

Right now, US exceptionalism remains a consensus market narrative. But Australia is not without its advantages. And economic and political uncertainty in the US remains a downside risk to ongoing US equity market performance.

We are cautious on the outlook for both US and Australian equities, given the elevated valuations described in Risk 1. However, given the relatively less stretched overvaluation in Australia, there is scope for Australian equities to deliver benefits within a diversified portfolio.

Risk 3: Active managers outperform passive indexes

Active managers have had a challenging time beating benchmarks over the past several years. There are several conditions that have made it difficult to outperform. Key among these is the extreme market concentration driven by US mega cap stocks. As these companies have grown as a share of the index, active managers have struggled to match returns from the very strong index rally in 2024 and early 2025.

Chart 5: % of managers that outperformed their benchmark in 2024.

Some active managers have performed better more recently. As an asset class, small cap managers did a good job outperforming their benchmarks in 2024 – although absolute performance was less strong.

Chart 6: In 2024, 54% of ASX200 stocks underperformed the index.

Chart 6 shows excess returns in the ASX200 were very narrowly distributed in 2024. More than half of the equities in the ASX200 underperformed the index. This started to change in 2025.

2026 is shaping up to be a potentially stronger year for stock pickers. Valuations are stretched, volatility is increasing, and rotations between sectors and factors has increased.

For investors, we think that while index allocations remain a valuable tool for portfolio construction, active managers may prove to be a valuable source of diversification and risk management over the medium-term.

Risk 4: AI fails to deliver

The artificial intelligence narrative has been the key driver of equity market returns over the past three years. The expectation that AI will permeate the economy and drive material productivity enhancements, support margins and sales, has driven equity market valuations to historic high levels.

It seems clear that AI will be an important part of the global economic outlook. In the US, the contribution to GDP from investment in information processing equipment has matched the contribution from consumption. Without that capex investment, the US may very well have already slipped into recession.

But it is less clear yet that all of the promise delivered by AI will be met. There are a number of risks that can be identified to the prevailing narrative. For example:

· A slowdown in AI capex spending could occur.

· AI could fail to improve materially from its current state.

· There could be a failure of widespread user cases for AI in the broader economy.

· There could be an accounting scandal because AI companies are depreciating their capital expenditures over ten years – well in excess of the likely useful life – which can boost reported profits at AI companies.

For investors, exposure to the AI theme has been an important driver of returns. But that has resulted in material concentration risk and exposure to a single thematic. We think diversification remains critical within equity market sleeves, and, given the significant rally over recent years, it makes sense to build resilience within equity sleeves.

Risk 5: Interest rates fall below market expectations

The rate cut in September was positioned by Fed Chair Powell as a risk management cut. But I expect the Fed is going to be cutting rates over the remainder of 2025 and into 2026. The market currently has 4 more cuts priced in, which seems broadly sensible.

The challenge for investors is that rates could be cut for different reasons. It could reflect a carefully implemented gradual reduction in rates from restrictive to neutral, allowing the US economy to stabilize without material inflationary pressures. On the other hand, the Fed may be forced to cut rapidly as the economy continues to slow, even as inflation remains sticky.

Chart 7: Rates could fall because markets are anticipating a slowing economy as job gains collapse.
