Beware of the Sharpe ratio - Use the Sharpe ratio
The new paper "How to use Sharpe Ratio" is an important reading for any analyst attempting to compare two managers or strategies based on the Sharpe ratio. Many of the implications associated with the Sharpe ratio have been discussed in previous papers; however, this one presents all the limitations and possible solutions in a single reading. The authors present several adjustments to the Sharpe ratio to account for issues such as non-normality, but they also list and comment on all past research that has been associated with the Sharpe ratio. The overall conclusion is that using quick calculations should be done with peril. Oftentimes, minor adjustments will help on the margin. This is important because often Sharpe ratios for many strategies are close to each other, so rankings will flip once you account for some of these adjustments

Central banks like gold more than Treasuries
This is one of the most interesting charts this month. Central banks have kept more gold than Treasuries for an extended period until about 1997, when there was a switch to holding more Treasuries. This was the period of Bretton Woods II, when central banks increased their reserves as a measure to help defend their currencies in a crisis. Now, these central banks prefer gold over the safe asset of Treasury securities. There is a fundamental change in the perception or common knowledge concerning Treasuries as a safe asset.

Economics and the need for history
"Forty years of investment in mathematizing economics has made it less acceptable among economists to admit ignorance of mathematics than to admit ignorance of history" - Deirdre McCloskey
You cannot be an economist today without knowing your math. To complete any PhD program, you will need to possess a strong understanding of mathematics, statistics, and econometrics. You will also likely have strong programming skills. Finance is being dominated by quants.
You will not need to know history in this environment; yet, as I get older, understanding history becomes a critical skill. All policy analysis needs context for what has worked in the past. You need history to describe "experiments" in the past. The past determines the path for the current and future.
In finance at the local level, you need to know the history of companies; their evolution is relevant. At the macro level, we need to know the specifics to appreciate our generalizations. It seems that one semester of economic history is not too much to ask for our experts.
This has been a common theme on how we think.
Finance needs more history to help with the future

Liquid Alternative Beta (LAB) performance for August
The Liquid Alternative Beta (LAB) indexes, available from HedgeIndex, formerly Credit Suisse, offer a comprehensive view of the performance of various hedge fund strategies in August. All the hedge fund strategies were positive for the month. Returns were consistent with the overall market, SPX, which gained 2.03% for the month. The LAB indexes beat the S&P500 growth and momentum factor-based indexes. The global strategy and managed futures indexes were able to take advantage of the tail winds from positive international equities and bond returns. This places most strategies with positive returns for the year, except for the managed futures and liquid indexes. The managed futures strategy has started to find trends after a difficult first half of the year.
The LAB indexes have lower volatility than the long-only benchmark strategies.
Prediction is not optimization
Many researchers and practitioners have questioned how the input parameters of MVO should be estimated. To this, Markowitz is said to have responded with wit and grace, “That’s your job, not mine.”
- Stephen C Sexauer and Laurence B Siegel. 2024. Harry Markowitz and the philosopher’s stone. Financial Analysts Journal
With the quant revolution, there have been significant advancements in the methods and types of optimization that can be used for portfolio management. However, the key to successful optimization remains the accurate predictions of expected return, volatility, and correlation. Optimization on the wrong inputs is a fool's errand.
The machine learning explosion has to focus on system predictions across a large set of assets, which can then be used as inputs into a traditional optimizer. Before using an optimizer, focus on the input variables.

European versus American trend-followers
A recent paper, "The Science and Practice of Trend-following System", makes the interesting observation that there is a difference between European and American CTAs or trend-followers. The paper tries to provide a unified system for trend-following, a noble cause. However, what piqued my interest was the authors' comment that there were three major trend-following classifications: European, American, and time series momentum.
I have always believed and commented that there is a difference between the major European and American trend-followers. I have stated that Americans are ideologues who adhere to a system developed in the 70's and 80's, while Europeans are pragmatists who focus on any technique that seems to generate profits. Sepp and Lucic hold the view that European CTA focuses on continually adjusting positions based on current risk, coupled with exponential moving average systems. American trend-followers emerge from the technical system world, focusing on breakout systems that involve full positions based on the signal. The third system focuses on time series momentum systems, which are correlated with moving average crossover systems.
You might think that these approaches are all the same, but you would be wrong. The American system has the highest Sharpe ratio, but the other methods are not far behind. In a given year, there will be differences, but it is hard to say that one approach is superior to another. You are left with the issue of finding a strategy that works for your risk tolerance, and in this case, risk tolerance is based on your comfort with the return generation process.

Jerome Brunner - Logic and narrative go together
Jerome Brunner, one of the towering figures in psychology and cognitive learning, developed a simple cognitive theory through framing experience into two models, propositional and narrative. Propositional thinking focuses on logic and formality, while narrative is based on storytelling. Narrative is emotional and needs to be personally convincing. It is the narrative that holds the propositional logic together as a useful tool. Simply put, we cannot develop theory and logic in a vacuum; instead, we use narrative as a tool to support our thinking or convey it through stories. The narrative provides an emotional connection.
We can use that framework to think about how stories are conveyed on Wall Street. Nothing is done through a review of model results. No talking head refers to a model. The models are condensed into a concise story or narrative. The narrative can provide a connection that is not present in a model.
Perhaps an extreme, but Fed independence is not presented as a formal problem in time inconsistency, but as a fight for control over a policy lever. The acquisition of a firm is not described in terms of numbers, although a price is associated with the purchase. There is a discussion of strategic advantage and how the whole will be greater than the sum of the parts.

Financial globalization is determined by state actors
State and the Reemergence of Global Finance: From Bretton Woods to the 1990s by Eric Helleiner is a fascinating book on the politics of international plumbing. As a macro person, I focus on models and price relationships, rather than regulation or international relationships across countries. This book highlights the significant impact of global policy choices by states on markets. This should be viewed as obvious, but we often focus on innovation and market forces as the drivers of change; however, it is frequently the will of the state that is the major contributing factor. Financial globalization was not an organic change to the international order but was orchestrated through the policies and dictates of state players. This was a different perspective that I did not fully appreciate.
Clearly, the world is being reset with respect to trade through tariff policies; however, we cannot forget that the world can also change through policies that impact capital markets and flows. Capital markets may have a greater impact on inter-country dynamics. While we have not seen capital flow policies change directly, the talk for a weaker dollar is clearly having an impact on flows. The sanctions placed on countries also have a flow constraint. We have not changed policies on capital controls, but the weakening of international organizations has spillover effects on capital flows. Financial globalization or deglobalization is in the hands of policymakers, and should be given more attention by all in finance.

What if Treasury bonds are not a safe haven?
The convenience yield for Treasuries
BlackRock suggesting higher allocation to hedge funds
The BlackRock Investment Institute announces that investors should increase their allocation to hedge funds. It is not clear what the rationale is for this increase. Equity markets are overvalued and bond yields are not expected to move lower. Private equity is facing liquidity issues. Hence, hedge funds are a safe haven by default. As a diversifier, hedge funds may do the job, but the story should be more nuanced. Stock-picking has improved with market dispersion, but many hedge funds have relatively high betas. If the market moves lower, hedged funds will likely also see lower returns, albeit muted.
The choice of hedge funds and the allocation are related to a market view. If there is a view that equity and bonds will not perform because of the macro environment, investment strategies should be focused on managed futures and global macro. For equity exposure, market neutral should be preferred.
However, there is a bigger issue associated with fund flows. If there is limited alpha, what will happen to returns if there is a major increase in fund flows into hedge funds? There has not been enough work on the flow effects on alpha returns. More money chasing the same number of opportunities will lead to lower returns. Part of good investing is being in strategies before the "big money" enters the trades.

The current problem with government statistics
In contrast to physics, there is no estimate of statistical error within economics in spite of Oskar Morgenstern’s book, On the Accuracy of Economic Observation. The problem of error in economic observations is still a widely neglected problem. The various sources of error that come into play in the social sciences suggest that the error in economic observations is substantial. As the error might be substantial, this paper argues that the usefulness of econometrics becomes questionable. - Philipp Bagus Rey Juan Carlos University
The multiple news stories about the change in leadership and the BLS miss the key point that we are facing with macroeconomic analysis. We are only as good as the data that we use. If there are significant errors with the underlying data used to make macro decisions, there will be greater market inefficiency. Major revisions will reduce he trust in the numbers. Minor modifications will help investors refocus their attention on this data. The market reaction to any announcement will decline. It is not that the market will make wrong judgments based on the data, but that no judgment will be made at all. There will be less market reaction on any announcement date, yet there is likely to be greater misallocation of resources.
Gold and the problem of fiat money
The US government has consistently tried to marginalize gold, and has all of the focus on the dollar, but that only works if we behave ourselves. If we add a lot of debt on top of a fiat currency, it doesn't work.” - Chris Walen

The quantity theory of money still exists
Tim Congdon authored a new book, The Quantity Theory of Money: A New Restatement, last year. It is a historical retrospective of the classic quantity theory of money with some new twists. It is not a easy book for those who are not familiar with the long history of money. It takes a number of twists and turns on why some explanation do not work, but in the end, Congdon again emphasizes that money is at the heart of any discussion of inflation.
The key insight is that money will impact not just the bond market which is the traditional view in the classic IS-LM modei but will also affect othe asset markets and goods markets. Money seeps into everything we do. We have to also focus on broad money, and how it affects asset purchases and goods purchase decisions. The link between money and credit is a better description of how it impacts transactions nd prices than the simple Friedman money multiplier.
The inflation post-COVID should not have been a surprise for anyone who follows the money trail.

A very important book even for finance people - Autocracy, Inc.
I don't often comment on non-finance issues, but I was moved after reading Autocracy, Inc. by Anne Applebaum. This was not an emotional feeling, but anger that the autocrats of the world are forming connections to maintain their power in their respective countries. These autocratic connections are thwarting democratic movements around the globe. Applebaum provides good descriptions with substantial evidence on how dictators want to work together for their common benefit.
The solutions to this problem are not obvious; however, there needs to be some form of international order and coordination between Western democracies to ensure that the global behavior of dictators does not rule over others. A coalition of democracies needs to actively engage in efforts to stop autocratic coordination. Obviously, this is being done, but the efforts have not been strong enough.

The next credit crisis - student loans again?
Corporate spreads are at all-time lows and household finances seem to be in good shape, but there is one area of concern - student loans. There was an extended moratorium on student loan payments during the Biden Administration due to the COVID pandemic, but that is in the past. Borrowers now have to pay up, and the bailouts are not there. The result has been an increase in delinquencies. This is especially the case for older borrowers who are nearing retirement. We are not at a crisis, but this is an area of concern that impacts spending and the ability of these consumers to take on any other debt.

HedgeIndex July performance - generally on track
We look closely at the HedgeIndex Liquidity Alternative Beta indexes that are replications of the HedgeIndex Composite Index returns. As a liquid alternative, investors can get a quick look at performance before many hedge funds report their monthly returns.
Returns were positive except the managed futures index, which continues to have a difficult time finding trends in the major futures markets. If there are no trends, the trend index will not make money. The other strategies continue to show positive gains. Nevertheless, the Liquid and Global Strategies are a weighted average of the other strategies and have been pulled lower in 2025 by the managed futures performance.
While the SPX generated a return of more than 2% for the month, these liquid alternatives have a lower volatility than the market beta. The LAB indexes performed better than the low volatility index, which returned a negative 29 bps this month. These indexes are not supposed to beat the major risk factors but should add diversification to any portfolio. The equity LAB indexes performed better than the fixed income composite.
A Simple rulle of thumb on trading - the 3M's
"Markets always trading the 3Ms… Macro, Momentum, and Misfit trades" - Michael Hartnett BofA.
I like this short description of trading because it covers almost all you need to know. Trade the macro or at least have the macro determine the asset allocation. Trade the momentum or the trends because this is a risk factor that usually works. Trade the misfits or the outlier anomalies that are away from fair value. This is it. This is all you need to know as the base case. From there, the real work begins on how to make this work with actual trades.
