2025 in review and our 2026 outlook

9/1/2026

 
Equities have recovered strongly from the tariff shock earlier in the year. Dollar weakness vs Sterling has weighed on the relative performance of US equities; however, this was a step-change and there are concerns for Sterling too.  Gold has continued to perform very strongly on the “debasement trade” and Central Bank buying.  Within Bonds, Emerging Markets are in better shape than Developed Markets, in our view.

deepseek ai vs chatgpt - what it means for markets

28/1/2025

 
Picture
What is Deepseek?
The new Chinese AI tool is the most downloaded app in the US and claims to be able to operate quicker and more cheaply than Chat GPT.  By requiring fewer chips and smaller server farms, DeepSeek can deliver its AI generated results, which incorporates self-corrective learning, at lower cost.  The arrival of DeepSeek in the AI field creates a challenge to Chat GPT and also means more could potentially be done with fewer advanced chips. The DeepSeek app is free, and its code is open source, which means companies in the US can easily create similar copycat versions of it. Its AI model is called R1 which has some 670 billion parameters, making it the largest open-source LLM (large language model) yet. The R1 is unlike traditional models that immediately generate responses. The R1 are trained to think extensively before answering. Its approach is similar to how a human carefully considers a complex problem before answering it. The method is known as test-time compute and requires the model to spend up to minutes working through its chain of thought. The company estimates it has cost $6 million to train the model compared to other AI models which cost over a $100 million each. The app challenges the notion that the only way of building better AI models is by spending large amounts of money buying high powered processing chips.

What happened to NVidia stock?
Lower potential demand for chips has led to a rapid sell-off in NVidia shares, which declined -17% in 1 day on 27th January 2025.  Because of NVidia - and the broader technology sector's high exposure within the S&P 500 this led to a US equity market sell off, dragging down market-cap weighted world equity indices too. Other stocks which suffered similar down moves were Oracle (-13.79%), Cisco (-5.06%), Broadcom (-17.40%). These companies along with Nvidia provide important components in building data centers and digital infrastructure to support training AI models. NVidia released a statement saying "DeepSeek’s work illustrates how new models can be created using that technique, leveraging widely-available models and compute that is fully export control compliant." While President Trump said the breakthrough in technology is a positive for America and that it is a wake-up call for US tech firms to not rest on their laurels.

Elevated concentration risk in the US equity market is well-documented and one of the reasons we recommend advisers we work with to balance traditional S&P500 market-cap weighted exposure (which was down -1.46%) with S&P500 Equal-Weighted exposure (which was up +0.03%), and also for active selections within Sectors and Styles.

How much NVidia is in a portfolio?
For a balanced, well diversified portfolio built with funds, direct exposure to NVidia should not be more than 2% or so.  This reflects the importance of diversifying away from stock-specific "idiosyncratic" risk.

​Creative disruption requires diversification
As with any paradigm shift, it's hard to identify clear-cut winners in advance.  We welcome the AI revolution as a broader technological innovation theme to consider within portfolios.  But this episode emphasises the value of having a diversified approach.

2024 investment review

3/1/2025

​
  • The US economy outperformed expectations
  • The long-awaited pivot came through
  • Portfolio resilience proved key

As we look forward to 2025, it is worth revisiting the themes and predictions of our 2024 outlook “turning the corner” to get a sense of what we anticipated at the time, how this informed our recommendations to UK adviser firms’ investment committees.  Asset class performance for 2024 is summarised in the chart above.  Our 2025 outlook is published separately.

Steady as she slows
In 2024, we anticipated a gradual deceleration in the U.S. economy, with markets pricing in the likelihood of a slight recession. In the event, the U.S. economy surprised on the upside. Growth forecasts were upgraded from 1.15% at the start of the year to an impressive 2.6% by year-end. This revision supported robust equity market returns and served as a reminder of the resilience of U.S. economic fundamentals.  In summary, a resilient US economy defied expectations.
What did we recommend to our clients at the outset and during the year? We took a balanced view between accepting concentration risk (traditional S&P 500) and diversified (active, sector exposures).  We also recommended clients lean in to broader US equity corporate landscape via 1) Equal Weight and 2) US Small Caps exposures.
By contrast, the UK had that shrinking feeling as regards economic growth, and although out of a technical recession, we are not confident of its prospects relative to the US.

Pause before pivot
At the close of 2023, we were focused on the Federal Reserve’s pause in interest rate hikes, noting that a rate cut was a question of when, not if. While the consensus view was that the first cut would be announced by mid-2024, we anticipated that the timing would hinge on the performance and strength of the U.S. economy. Indeed, the economy’s resilience delayed the start of what we anticipate to be a rate-cutting cycle to September 2024, when the Federal Reserve finally delivered a significant 50-basis-point cut.
In fact, the eventual BoE Fed pivot came a month or two later than we had estimated at the start of the year, but we recommended our clients remain dynamic with regards to duration management.  We recommended clients go strongly overweight duration in June as a good time to extend duration ahead of BoE cuts, with Fed following suit, and we saw the additional duration deliver returns on the bond side of the portfolio before attention shifted to debt supply and the UK budget later in the year, which led us to recommending to move back to neutral.

The importance of portfolio resilience
Our focus on resilience proved vital when it came to navigating the key macro factors in 2024: Growth, Inflation and Interest Rates.
For Growth, anticipating a soft landing for the US economy, we highlighted the potential outperformance of cyclical sectors, and momentum, yield and size factors. In the event, momentum emerged as the best-performing factor, with yield and size also delivering strong returns. For Rates, we adjusted duration exposure mid-year to capture the effect of falling policy rates, aligning portfolios with a changing interest rate environment. For Inflation, which remained above target, the inclusion of liquid real assets (but to a lesser extent than in 2022) and shorter duration inflation-linked bonds, ensured continued portfolio resilience.  We continue to emphasise the importance of a diversified alternatives exposure from a correlation perspective, not just in name.
Our recommendation to consider Private Market Managers and Gold & Precious Metals paid off during the year – as these were the best performing asset classes for the year, outperforming world and US equities.

Political and Geopolitical risks
In a year of elections, we saw a change in government in the UK and in the US following Trump’s Presidential win.  Both have a greater impact on bond yields and currency dynamics than equity markets, in our view.
Geopolitical risks remain elevated with the Russia-Ukraine war continuing to grind, escalating conflict and contagion in the Middle East – all at tragic human cost.

Conclusion
Markets did indeed turn a corner in 2024, with economic growth, earnings and equity market returns outperforming expectations.  With 2024 in the rear-view mirror, it’s time to look ahead to 2025.  Our 2025 outlook is published separately.

2022 proved to be a challenging year with pressure on equities and bonds a like in face of rising rates and soaring inflation.  In our 2023 Outlook: Looking for Light, we explore three key themes
1. Yield is back: for equities, bonds and alternatives - the yield drought is over
2. Selectivity matters more: within and across asset classes
3. Inflation is getting stickier: getting past the peak, but still a problem

​
  • Pandemic winners are suffering a fall from grace
  • Inflation risk is re-rating frothily valued sectors
  • Market uncertainty driving investors to dependable businesses
 
The uncertainty of the current market environment is prompting a pivot away from sectors that have served investors well, in many cases since the financial crisis but particularly during the Covid-19 pandemic. With inflation rampant, commodity prices spiralling, supply chains choked and the much relied-on ‘Fed Put’ (whereby central banks rescue markets by flooding them with liquidity) a thing of the past, investors are rotating away from Technology and Real Estate and into traditionally “boring”, but dependable sectors like Industrials, Materials and Energy.

2022 outlook: key themes

11/1/2022

​
  • Adapting portfolios for inflation
  • Income generation in a negative real yield world
  • Positioning portfolios for climate transition
 
2021 in review
Our 2021 market roundup summarises another strong year for markets in almost all asset classes except for Bonds which remain under pressure as interest rates are expected to rise and inflation ticks up.
Listed private equity (shares in private equity managers) performed best at +43.08%yy in GBP terms.  US was the best performing region at +30.06%.
Real asset exposures, such as Water, Commodities and Timber continued to rally in face of rising inflation risk, returning +32.81%, +28.22% and +17.66% respectively.

2022 outlook
We are continuing in this “curiouser, through-the-looking glass” world.  Traditionally you bought bonds for income, and equity for risk.  Now it’s the other way round.
Only equities provide income yields that have the potential to keep ahead of inflation.  Bonds carry increasing risk of loss in real terms as inflation and interest rates rise.
Real yields, which are bond yields less the inflation rate, are negative making traditional Bonds which aren’t linked to inflation highly unattractive.  Bonds that are linked to inflation are highly sensitive to rising interest rates (called duration risk), so are not attractive either.
How to navigate markets in this context?
The big three themes for the year ahead are, in our view:
  1. Adapting portfolios for inflation
  2. Income generation in a negative real yield world
  3. Positioning portfolios for climate transition
We explore each in turn, as well as reviewing updated Capital Market Assumptions for expected returns from different asset classes.

Fed up with cap-weighted indexes? Then don’t use them

12/1/2021

 
Picture

  • Tech performance is skewing cap-weighted indices
  • Increased concentration reduces diversification
  • Using cap-weighted indices is an active choice
 
Tech performance is skewing cap-weighted indices
The run up in technology stocks and the inclusion of Tesla into the S&P500 has increased both sector concentration and security concentration.  The Top 10 has typically represented approximately 20% of the index, it now represents 27.4%. 
The chart below shows the Top 10 holdings weight over time.
Picture
Picture
​Rather than looking just at Risk vs Return, we also look at Beta vs Correlation to see to what extent each strategy has 1) not only reduced Beta relative to the market, but also 2) reduced Correlation (an indication of true diversification).  Strategies with lower Correlation have greater diversification effect from a portfolio construction perspective.
Ironically, the last time the index was anything close to being this concentrated was back in 1980 when IBM, AT&T and the big oil majors ruled the roost.

From a sector perspective, as at end December 2020, Information Technology now makes up 27.6% of the index.

Increased concentration reduces diversification
This level of concentration is indeed skewing indices that rely on a traditional market capitalisation-weighted (cap-weighted) methodology, and does therefore reduce diversification.
But the issue of the best performing stocks getting a larger weighting in the index, is not an accident of traditional index design.  It’s its very core.  Cap-weighted indices reflect the value placed on securities by investors, not the other way round.

We should not therefore conflate the debate around “active vs passive” investment approaches, with the debate around index methodology.

If portfolio managers are concerned about over-exposure to particular company or sector within a cap-weighted index, they can either chose an active, non-index fund, that is not a closet-tracker.  Or they can access the target asset class through an alternatively weighted index, which uses a security weighting scheme other than market capitalisation.

Using cap-weighted indices is an active choice
The decision to use a fund that tracks an cap-weighted index is an active choice.  And for those seeking differentiated exposure, there is a vast range of options available.

We categorise these into 3 sub-groups: Style, Factor-based and Risk-based.
  1. Style-based: for example: Value, Growth, Income.  This is the classical style-based approach.  Value investing traces back to Graham & Dodd’s research in the 1930s.
  2. Factor-based: for example: Value, Size, & Quality.  Factor-based investing weights securities by their internal fundamental characteristicss that relate to their expected drivers of returns: for example securities included in a Quality index would be included based on profitability and/or Return on Equity metrics.  Min Volatility (lowest and Momentum relate to the performance of the security rather than its fundamentals.  Our recent CPD webinar explores factor-based investing in more detail.
  3. Risk-based: probably the least developed area.  Risk-based investing weights securities by their relationship to each other in order to target a particular target risk characteristic.  Examples include: Max Deconcentration (aka Equal weighted); Max Diversification; Max Decorrelation; Max Sharpe; Min Variance, Risk Parity (aka Equal Risk Contribution) and Managed Risk.  Our recent CPD webinar explores risk-based investing in more detail.
  4. Min Volatility or Min Variance? What’s the difference? Semantics, but for differentiation, we refer to Min Volatility when a strategy ranks securities by their volatility, to include only those lowest volatility stocks (hence used when referring to Factor-based strategies).  We refer to Min Variance when a strategy looks at risk and correlation structure between stocks to target a “minimum variance portfolio” of those securities (hence used when referring to Risk-based strategies).  So similar, but different.
With that array of index methodologies for US equities to choose from, there’s no excuse for complaining about being fed-up with the traditional cap-weighted approach.  Index selection, depends, of course, on portfolio construction objectives, and index methodology due diligence remains key.

How have US equity risk-based strategies fared?
Risk-based strategies have been in existence for some time, so we are able now to consider 10 year data (to December 2020, in USD terms).  In terms of risk-adjusted performance, Managed Risk index strategies have fared best, whilst Min Variance has delivered higher returns for similar levels of risk of a Max Diversification strategy.  Meanwhile Equal Weight has actually exhibited greater risk than traditional cap-weighted approach.
Picture
In this respect, Equal Weight (Max Deconcentration), also disappoints delivering higher beta and >95% correlation.  Likewise Min Variance, whilst delivering on Beta reduction, does not deliver on decorrelation.  Max Diversification delivers somewhat on decorrelating the strategy from the S&P500, but only modestly, whilst Managed Risk achieves similar decorrelation, reduced beta and better returns.  Finally Risk Parity 10% Volatility cap has delivered most decorrelation as well as beta reduction.
For more information about the indices and funds used to represent these different strategies, please contact us.
​
Summary
There are a broad range of alternatives to cap-weighted index exposures.  But consideration of style-, factor- or risk-based objectives will necessarily inform portfolio construction.
  • Fiscal and policy support should keep growth shock short and sharp
  • Inflation looks bottled – for now, but this is the key focus
  • Asset price recovery was welcome but vigilance now required
