SubStack NOTES:
GPT-LLM-ML: Use as a natural-language interface to a reliable and ideally well-structured database is, I think, one of the use cases for LLM's that is actually likely to be very useful soon. And Dave Guarino is on it!:
Dave Guarino: Using AI to make sense of policy documents <http://daveguarino.substack.com/p/using-ai-to-make-sense-of-policy>: ‘I've been experimenting with using AI to do "policy reasoning." That’s because fundamentally this is what staff have to do to answer questions about often complicated and complex rules.…. I think… pairing a policy question in an end-user’s own language with the specific policy language that a government staff member would use to answer it… [is] of promise…. I am working on experimenting and evaluating more. There are definitely ways that this would need to be hardened to be used in something closer to a production (real users) environment. Though my first step would most likely be to have a human in the loop, with something like an email support desk or a content web site as the service channel. (That mitigates a lot of the risk of having it be instantaneous)…
Economics: Somewhere along the road, orthodox finance economists lost the plot.
The Efficient Market Hypothesis was, originally: the market knows more than you do, and so you cannot “beat the market” in utility terms—if you do find a systematic way to “beat the market”, it will be because in the states of the world in which you receive high returns each unit of wealth is worth less to society than in the states of the world in which you receive low returns. You can benefit by holding other than the market portfolio if your rate of time preference is different from the market’s or if your tolerance for risk is different from the market’s or if your alternative portfolio aligns incentives. But you cannot beat the market.
But the returns to beta were never, plausibly, there because in the states of the world in which you receive high returns each unit of wealth is worth less to society than in the states of the world in which you receive low returns. And such claims for small vs. large, value vs. growth, robust vs. weak profitability, and conservative vs. aggressive on investment were an order of magnitude even more ludicrous.
So you can beat the market, by a lot over time, if you are patient and are willing to do five things systematically.
That is not an “Efficient Market Hypothesis”. That is a “Systematically Inefficient Market Hypothesis”. And only those for whom confusion is a friend and chaos is a ladder have any business calling it the EMH:
Market Sentiment <https://www.marketsentiment.co/p/great-expectations>: ‘Leverage Factors: The past 6 decades of data show us that 5 factors were able to explain 95% of the differences in returns between diversified portfolios (all figures are annualized). a. Market Risk (MKT-RF): The market beat one-month treasury bills by 5.37%. b. Size (SMB — small minus big): Small stocks beat large stocks by 2.04% c. Value (HML — high minus low): Value stocks beat growth stocks by 2.68%. d. Profitability (RMW — robust minus weak): Highly profitable companies outperformed weakly profitable companies by 2.8%. e. Investment (CMA — conservative minus aggressive): Companies that were conservative in asset growth beat aggressive growers by 2.93%. What this shows us in simple terms is that even if we believe in the Efficient Market Hypothesis, certain factors would get us better results through long-term exposure rather than just sticking to market-cap-weighted index funds…
War: There is something very, very wrong with Michael Ignatieff. Binyamin Netanyahu is not a person with limited options being “driven” “toward annexation and expropriation” by spoiler “settlers”. The the entire point of his government is to grab land. If, in the process, that gins up enough Arab rage to make the Israeli electorate reluctant to support more peace-oriented politicians—well, that is all to the good, from his perspective. The only thing he did not want was for so many Israeli civilians to die on October 7:

Oks & Williamson: ‘With the global population outside of Africa entering a long era of slow growth or decline, and African population in the midst of a long and spectacular boom, the future of development and poverty reduction will hinge on the future of Africa.

Well. I see that Krugman, in his column today, takes the same line that I did ... except that he thinks the confidence fairy is less plausible than I do. Not gonna lie, I'm feeling a little bit vindicated here, Brad. You were the one who came up with The Krugman Rule! :-)
Foser: I'm not a fan, but if Hanania were the world's worst racist, that would be a pretty good world.
