China global financial stress elevated but not unusual
Rates versus absolute change - Mistakes that investors make that matter
Behavioral biases exist and they really do matter for both the individual investor and markets overall. A provocative paper attacks one of the more obvious problem in finance that should have been explored much earlier. The paper, "Can the Market Multiply and Divide? Non-proportional Thinking in Financial Markets" studies the problem that investors don't seem to understand the difference between a $10 price change and 10% or proportional change.
We may be so used to hearing financial data presented in a certain way that we don't even notice the problem. A commentator will say stock x is up $5, or the benchmark index is up Y points without saying the percentage change is contributing to the bias.
This problem becomes obvious when you scale values by price, a $x change in a stock that has a low price will have a very different meaning from a $x change in a higher priced stock. Proportionality matters. Ineffective juggling between dollar price and percentage changes is a problem for the individual, but when explored at the market level it can explain some of the odd anomalies or puzzles seen in the stock market.
Investors usually think about dollar not percentage units which leads to more extreme responses to news for lower priced stocks. Higher price stocks will be less volatile - a doubling in price will lead to an approximate 25% decline in volatility. Consequently, volatility jumps after a stock split. Lower price stocks will respond more strongly to firm-specific news. This non-proportional thinking can explain size-volatility/beta relationships, the leverage effect and return drift.
Guard your thinking through always thinking about the proportional impact of prices.

The "extreme precariousness of the basis of knowledge"
"The state of confidence, as they term it, is a matter to which practical men always pay the closest and most anxious attention. But economists have not analyzed it carefully.... Our conclusions must mainly depend upon the actual observation of markets and business psychology.... The outstanding fact is the extreme precariousness of the basis of knowledge on which our estimates of prospective yield have to be made. Our knowledge of the factors which will govern the yield of an investment some years hence is usually very slight and often negligible."
- Chapter 12 "The State of Long-Term Expectation" from The General Theory of Employment, Interest and Money" John Maynard Keynes
I like the term "precariousness of the basis of knowledge". I had to help with a private company valuation in a fast-changing industry. The difference in valuation given some simple assumptions was enormous, and I was using some very standard valuation techniques.
The same uncertainty problem applies to any forward estimate of rates, inflation, or the dollar. Perhaps we can speak to trend or views in the short run, but the range of potential estimates out to a year or more is so wide to be almost useless. Our only savior is the range of past behavior over a year horizon, but in a highly uncertain macro environment that conditional restriction may also work against an effective forecast.

J Powell - The easy choice, but perhaps not the right choice
With Fed monetary policy at a crossroads, the conventional wisdom is that it is not good to change the chairman when there is policy choice uncertainty. Given the policy choices of the past few years and the choices ahead, it is not clear what is the value of conventional thinking other than a new choice may create even greater uncertainty.
Chairman Powell was the easy choice, but it may not have been the right choice. Taper speed will be an issue. Inflation is an issue. A rise in rates is an issue. Global finance is an issue. Bank regulation is an issue. Many of these issues are the making of the Fed. The argument will be made that the Fed did the best job possible given the events of the pandemic, and any criticism is just ex post sore grapes. We are not questioning the response in March 2020. The issue is the length and intensity of policy which now weighs on markets.
The tougher choice would provide some fresh perspective and admit there may have been mistakes, but that would have been in opposition of existing administrative thinking. The easiest choice is to accept that any failure could not have been avoided because the environment is out of the Fed's control, and they did the best it could.
Should Lael Brainard been given the nod? She is smart and talented, but it will not matter if the core policies are unchanged. We will see her skills put to the test as vice-chairman. This appointment should be a positive.
Both Powell and Brainard have commented on inflation being the top problem to be addressed in their thank you responses. This is a turn-around from the last few months. The market reaction was swift. The real question is how much the Fed is going to change course and become more aggressive addressing the inflation question now that the announcement has been made. Hearings are ahead, and both must now get in control of inflation.
Just-in-time strategy for an investment/trading portfolio
There is value from reading older work on strategic management and applying it to the money management industry. It gives a different perspective with needed structure for making better investment and business decisions. I found an old work "Just-in-time strategy for a turbulent world" by Lowell L Bryan useful for investment thinking. The core concept is that there should be diversification of projects - a diversification of timing for payback and risk as measured by familiarity.
In this just-in-time thinking, there are trade-offs between risk and timing horizon for an investment. Investor should think about having a mix of strategic trades and investments that may have different times to payoff with different types of risk. An investor should also think about the commitment of resources based on timing of pay-offs and the level of risk or familiarity of the project.
Risks can be classified according to relative knowledge or familiarity. There are low risks taken when you may have a high degree of distinctive knowledge that is unique to your organization. There are increased risks when others may have greater knowledge, and there is true uncertainty when there is difficulty with estimating payoffs.
Your level of trading or commitment to investing should vary with your level of familiarity. Greater investments and risks should be taken in highly familiar areas while low amounts of capital should be given to truly uncertain projects where there is low familiarity. When others have greater knowledge, limited investments should be made as a test or as basis for gaining knowledge. Nevertheless, if you only invest in project and trades where there is great familiarity, there will be a limit on growth and opportunity. If you only invest in uncertain projects, time commitments before a payoff will often be great.
The timing of resource investments can have an immediate payoff or will take time to provide a return. Firms should have a mix of projects to allow for long-term strategic growth. This thinking can be applied to research. There are short-term projects based on high familiarity, but those should be balanced against longer-term higher risk projects.

Trailing stops - the math says this is a complex decision

Beyond first order thinking ... second and third order matter more
What separates the great analysts from the good analysts? It is simple, second order thinking. Levels of thinking may lead to reversals in price from what is expected or market responses that are counter intuitive. A shock to a market may not behave as expected because money is flowing based on more complex thinking.
First order thinking is the result of immediate thinking based on what has been expected from the past. It is associated with generalized thinking, based on the concept that all else is equal. It is our initial fast thinking. It would be system 1 Kahneman thinking based on simple intuition. For example, higher gasoline prices will lead to less driving. This immediate conclusion is the end of thinking and does not involve the implications of initial actions. It is reactionary and safe thinking and will be the answer that the majority will use.
Second order thinking will extrapolate and think through the implications of what higher gasoline prices will have on other markets. It will question current assumptions and beliefs. This is system 2 thinking and is a deliberate approach to walk through the logical consequences of some action. It is hard focuses on uncertainty and complexity and my definition will not be conventional.
Second order thinking will walk through what other industries will be affected by the rise in gas prices. It will have an effect on refiners. It will impact travel and entertainment. It will impact demand for electric cars.
Third order effects will look at the implication of the second order effects to move to a third order. If there is higher demand for electric vehicles, there will be an impact on some industrial metals. Some of these higher order effects may prove to be illusionary; however, better analysts will think through events to form multiple hypotheses for opportunities.
Can a quant fund have second order thinking? This is very interesting question because a disciplined approach is often by definition literal. If "A" occurs, then do "B". The relationship between "A" and "B" has a sensitivity or coefficient of X, but the framework is very structured. Yet, second order thinking is critical for a good quant fund. A shock to one market may change the correlation among many assets. Second order thinking of a shock will look for correlation dislocations.
Think beyond the immediate or obvious and realize that others may also be thinking beyond the immediate. It is a game of anticipating the higher order thinking of others.

We just don't know much about inflation and money
I thought I knew about the causes of inflation and the link with money. I don't, but then others don't either. The conventional story is that higher money growth through QE should lead to lead to higher economic activity and then higher inflation if economic slack is diminished. The link may exist, but the sensitivities between money, growth and inflation are unclear.
We do have pre-COVID history from the BOJ, BOE, ECB, and the FED on massive QE programs with little evidence that inflation has greatly exceeded targets. We also have evidence that the money multiplier in all cases has fallen. The link between money and GDP has not been unstable rather it has been suggesting a desensitized relationship. See The International Experience of Central Bank Asset Purchases and Inflation by Gianluca Benigno and Paolo Pesenti.
Basics of data science - Machine learning is not econometrics
There are two cultures in the use of statistical modeling to reach conclusions from data. One assumes that the data are generated by a given stochastic data model. The other uses algorithmic models and treats the data mechanism as unknown. - Leo Breiman
Most analysts and investors who have gone to business school have taken at least one statistics class and perhaps an econometrics course. Business schools have integrated data science into the mix over the last five years, but finance has still been dominated by econometric thinking. With the econometric view, there is a proposed model for explaining markets. Data and statistics are used to test hypotheses and estimate parameters. Machine learning does not make any assumptions surrounding a model, rather the focus is on using data to make accurate predictions. If data is useful for predictions, then it has meaning.
From a practical perspective, data science techniques like machine learning focuses on engineering solutions. The goal is solely to predict and be accurate. There is no attempt to fit a model that can explain, although there may be a desire for the inputs to be intuitive.
The refocus on accuracy over causal reasoning should help with predictions; however, reasoning will be reversed. Inputs that provide an accurate forecast will now have to be assessed to understand their causal relationship with the variable to be predicted. Observational relationships obtained by machine learning will have to be given explanations. Nevertheless, data science should be embraced as a helpful investment tool.

IQ or RQ - The quotient of rational ability may be more important
“You don’t need to be a rocket scientist. Investing is not a game where the guy with the 160 IQ beats the guy with a 130 IQ. Rationality is essential,”
“Investing is not a game where the guy with the 160 IQ beats the guy with the 130 IQ. Once you have ordinary intelligence, what you need is the temperament to control the urges that get other people into trouble in investing.”
“If you have a 150 IQ, sell 30 points to someone else. You need to be smart, but not a genius,”
"Because you have all these smart people out there. The money doesn’t go to the people with the highest I.Q. There would be a very poor correlation between I.Q. and investing and results. And you say to yourself why does somebody with a 500-horsepower motor only get 100-horsepower out of it? And I would say that if you look at the intellect as being the horsepower that’s available, but you look at the output as reflecting the efficiency of that motor, it is rationality that causes the capacity to be translated in output."
-Warren Buffett
There is still a general mindset that IQ is a driver of success, yet the evidence points to a more nuanced view. There is a minimum intelligence needed for most jobs. That threshold may differ by profession, but it is not genius levels. Success is coupled with rationality which can be defined by several broad components —adaptive responding, good judgment, and good decision making. The smartest person in the room may not be successful if he cannot employ good decision-making.
The measurement of IQ (Intelligence Quotient) handles abstract verbal and quantitative mechanics, while an assessment of someone's RQ (Rationality Quotient) focuses on the ability to lay out a problem's logic as well as alternative analytical approaches. We have moved away from standardized IQ tests given our assessment that individuals can have several different skills, yet there has not been a willingness to add RQ measurement or testing to capture rationality.
Is rationality measurable? The answer is yes. While there are limitations like any testing format, questions have been derived to assess rationality. For more on this topic see The Rationality Quotient: Toward a Test of Rational Thinking by Keith E. Stanovich, Richard F. West and Maggie E. Toplak.
Investors should broaden their thinking on the skills necessary for success. Most have the minimum intellect, yet they need to assess and improve skills associated with rationality.

Liquidity down - risk up - A troubling sign for fixed-income
Government bonds are special because they provide liquidity when needed especially in a crisis. They are safe assets because you can buy what you want, when you want, at a price that is close to fair value and will not move when you execute size. Perhaps those days are over.
A look at top of the book liquidity suggests that liquidity is not there. If you want to trade size, you will move the market. Dealers are not present for immediacy. Rates have been so stable for so long that the big liquidity providers may not exist. There are traders in these markets but not sizable dealers.
There may be massive flows as financial institutions decide that monetary policy is changing, and it is time to hedge or rebalance a loan book, yet there are few who may take the other side of these trades for short periods to make a market. Treasury and German bond markets are seeing the same problem as the short-end of the curve. Liquidity is present for longer maturities. The result of a less liquid market will be investor avoidance. Don't play in markets subject to liquidity shortfalls. This will create a new policy problem. Will central bank have to serve as continuous liquidity providers to ensure that government bonds are a safe asset?

What if there was a "Great Bond Reset" and equities did not notice?
The front-end of yield curves for several countries have gone through a massive repricing in October. US 2-year Treasuries have doubled in yield during the month. Australian 2-years have increased by a factor five. There also have been significant moves in Sweden, Canada, and the UK. The great pandemic liquidity surge is over, or at least fixed income traders have said that the world has changed with higher inflation and policy will have to play catch-up. I don't want to say that bond vigilantes are back, long-end moves have been muted, but policy front-runners have made a statement.
So what do risky assets like US stocks have to say about this repricing? Not much. October saw a 7 percent gain in the SPY, a gain of over 8 percent for the top 50 stocks, and an increase of over 9 percent for growth stocks. High beta stocks are up over 50 percent above the benchmark for 2021.
Rates rises pushed forward in 2022, no problem. Slower third quarter GDP, no problem. Taper likely to start soon, no issue. Temporary inflation through the first half of 2022, still no worries. Yes, funds are available, but does this look like an early recovery environment? This looks like a cusp point into a new monetary policy regime.
