"Disciplined Systematic Global Macro Views" focuses on current economic and finance issues, changes in market structure and the hedge fund industry as well as how to be a better decision-maker in the global macro investment space.

Valuing start-ups mainly on scorecards
Risk is not uncertainty

Exiting at the wrong time - the key investor mistake
Themes drive the big returns in equities

Are the great minds leading to innovation?
“the great minds of the Industrial Enlightenment had shown how the useful knowledge they were accumulating could be used to improve, to rationalise, and to innovate. The rest is commentary” - 2025 Nobel Prize winner in economics Joel Mokyr
The burden on government and higher education is to better mankind, and that is best done through innovation that increases economic productivity. This raises living standards for all. It is not a matter of regulation but nudging greater minds to improve living standards. This is what is needed for the EU and for emerging markets. It is necessary for the US and China. Technology, not behavioral restrictions, improves lives. We need to focus more on how to use knowledge to benefit humankind.

The three big US economic surprises for 2025
There have been a few surprises in 2025. There are three that jump out as making a difference on performance.
1. Financial conditions have improved for the year after a rocky start
2. Trade uncertainty has fallen after spiking in the spring.
3. Revision to global growth has come through US and not other parts of the world
Do not worry about the 2025 predictions. Think about the surprises of 2025 and whether they will create spillover in 2026.

Bubbles and crash risk is associated with positive expectations
Momentum is persistent - A history

Stock-Bond correlation term structure
Momentum across different factors
Momentum can be displayed across different forms, and it seems as though each has different forms of persistence:
- beta
- country
- factor/style
- industry
- stock
The factor and industry momentum are strongly persistent over the short and intermediate run. Stock-specific momentum is persistent over the intermediate but not the short run. Beta and country momentum do not show persistence. This has important implications for how we use the momentum factor. These issues are described in the paper, "Optimizing the persistence of price momentum: which trends are your friends." The critical takeaway from this work is that while momentum is pervasive, there are areas or pockets of momentum persistence that can be exploited. These points of persistence are extreme with factor and industry tilts. Industry behavior moves together as well as factor behavior. This is not found in the overall market or with individual stocks.

The many faces of uncertainty
From the PowerPoint notes for the book Warren B. Powell, Reinforcement Learning and Stochastic Optimization: A unified framework for sequential decisions, John Wiley and Sons, Hoboken, 2022 (1100 pages).
This is a fascinating book that dives into the complex issues of stochastic optimization. At a high level, I found the description of many types of uncertainty beneficial. Only through dividing or classifying the many kinds of uncertainty can a researcher understand where the key risks are in a problem.
Is there data uncertainty or model uncertainty? Is the inference uncertainty or transitional uncertainty? If researchers can explore these differences, they can better define the risks faced and the sensitivity to a given answer.
It would be interesting to take a given strategy and decompose all the uncertainties faced.
The AI model used differs by task
I found this simple graph that matches how I use AI models. There is not one single provider that works best. The choice of AI model will differ by the task. Given these differences, I will sometimes use more than one model for he same task by asking the same questions or using the same prompts across several models and then comparing the results. Claude is easy to work with, but ChatGPT will sometimes provide more useful answers. Gemini and Co-Pilot are easy to use because of their integration with workflow, although their answers for more complex questions are not as clear.
While good at answering quick questions, their usage is harder to intergrate with normal quant work.
Bonds don't look cheap in current environment
Bonds are still in a bear market, but valuations still look cheap. The problem is determining the current fair value and whether there will be a move toward a new equilibrium. The simplest bond valuation will be real growth plus expected inflation plus any term premium. Expected inflation is above 2% and is unlikely to fall to the target rate. The real GDP is above 2% for the Blue Chip forecast and above 3% for the Atlanta Fed GDPnow forecast. Even if there is no term premium, we are looking at something close to the current 30-year Treasury yield and slightly higher than the 10-year yield.
The only way to pick bonds is to assume a slowdown in GDP and a decline in inflation. This is possible for 2026, but this is not the current environment.
You are making a large macro bet if you think the bear market in bonds will reverse beyond current levels.

Alpha and cost containment - The value of AI
We have written about how hedge funds are trying to contain costs by trading more efficiently. We are also seeing cost containment and efficiencies through the use of AI. Similar to consulting, AI can make analysts more efficient at some of their core tasks through summarizing and sifting through data in reports. The use of AI through EDGAR filing is not new, but has become a core part of the work by both discretionary and quantitative researchers.
AI is being used as:
- information summary tool
- focused search tool
- quick news analysis tool
- pre-screening tool along with quant analysis
- simple idea generator
- proprietary prompt tool
Alpha and cost containment - trading costs
Hedge fund performance centers on alpha generation. Alpha can come in many forms, but one that is clearly dominating the attention of many firms is cost containment. The drive to cost containment is based on two key components. One, there is relentless pressure from institutional investors to cut fees. With fees always pushing downward, firms have to become more efficient. Second, as hedge funds increase their trading volume, transaction costs become an increasingly important area for potential value creation.
By cutting trading costs, there is an immediate gain in return that flows through to the bottom line, reducing performance and incentive fees. Lowering the bid-ask spread improves returns. Executing with less slippage again enhances performance. The gain from cost containment is generally immediate and does not have to wait until ideas embedded in trades generate returns.
Cost containment is especially valuable to firms that are gaining scale. There can be specialized trading desks, centralized research, and risk management that can use economies of scale. All provide an edge that will squeeze out smaller firms that cannot gain economies of scale.

The great equity reset - global dispersion
There is no question that this has been a great year for Communication Services and the Information Technology sector, which are up 34.88% and 24.36%, respectively, for the year through November. Still, we are seeing cracks in these sectors with differentiation across the Mag 7. What remains the key theme to watch is the rotation into global equities and emerging markets, which are up respectively by 29.84% and 22.40% through November. These indices are beating large, mid, and small-cap US stocks by a significant margin.
Buying a broad set of US stocks is not the direction for success in the equity markets. We are seeing low correlation across US stocks and high dispersion. Investors need to be selective with their stock choices. This is a global stock-pickers market. If you are not a stock picker, you can see it in the differentials across risk premia. High beta and momentum factors are showing strong returns, while low volatility and dividend stocks are underperforming, even amid the current talk of market bubbles.
