AgPa #53: Investing in Interesting Times

Investing in Interesting Times (2023)

The Journal of Portfolio Management Multi-Asset Special Issue 2023, URL/AQR

Almost exactly one year ago, Antti Ilmanen (Partner at AQR Capital Management) released his outstanding book Investing Amid Low Expected Returns: Making the Most When Markets Offer the Least. The book is (in my opinion) a must-read and the timing couldn’t have been better. Many of the key themes began to materialize in 2022. Given how much markets have changed since then, Antti released a few updates for six of his major ideas in this week’s AGNOSTIC Paper.

  • The low expected return challenge
  • Investors’ response to low expected returns – private markets
  • What happened in 2022 and where we stand now
  • Long-only versus long-short strategies
  • Downside protection via trend-following

AgPa #42: Global Factors since 1800

Global factor premiums (2021)
Guido Baltussen, Laurens Swinkels, Pim van Vliet
Journal of Financial Economics 124(3), 1128-1154, URL

This week’s AGNOSTIC Paper is another out-of-sample test of the major factors and goes even further back in time than the last one. The authors examine the major factor premiums among equity indices, government bond indices, currencies, and commodities in a sample that ranges from December 31, 1799 to December 31, 2016.

  • Momentum, Value, and Low-Risk “worked” globally, in different asset classes, and out-of-sample
  • There is little evidence for factor decay

AgPa #41: US Factors before 1926

The Cross-Section of Stock Returns before CRSP (2023)
Guido Baltussen, Bart van Vliet, Pim van Vliet
SSRN Working Paper, URL

This week’s AGNOSTIC Paper is an unprecedented out-of-sample test of the four major factors (Momentum, Value, Low-Risk, Size). The authors construct a novel dataset of US stocks that reaches from 1866 to 1926. It therefore extends the extensively studied CRSP dataset by 60 years.

  • Momentum, Value, and Low-Risk were there before 1926
  • Factors weren’t stronger before 1926
  • Machine learning models find the same factors

AgPa #24: Market Capitalization vs. GDP

The big bang: Stock market capitalization in the long run (2022)
Dmitry Kuvshinov, Kaspar Zimmermann
Journal of Financial Economics 145(2), 527-552, URL

This week’s AGNOSTIC Paper is admittedly not very practical but probably more relevant today than ever before. The authors examine the outstanding performance of equity markets since the end of the inflationary 1970s and early 80s. A regime shift that they call the big bang. There are some surprising results, especially beyond the general debate about steadily falling interest rates…

  • The Big Bang: market capitalization detached from GDP growth after the 1980s
  • Most of the Big Bang comes from higher stock prices
  • Falling interest rates are surprisingly not the main driver
  • Higher profitability of listed firms is much more important

AgPa #15: Concentrated Stock Markets (6/7)

Extreme Stock Market Performers, Part I: Expect Some Drawdowns (2020)
Hendrik Bessembinder
SSRN Working Paper, URL

The sixth of seven AGNOSTIC Papers on the extreme concentration in stock markets. This one shows that even for the top wealth-creators, the road to success has been anything but smooth…

  • Even the best companies during their best decades had substantial drawdowns
  • Today’s drawdowns of tomorrow’s winners are even worse

AgPa #14: Concentrated Stock Markets (5/7)

Extreme Stock Market Performers, Part IV: Can Observable Characteristics Forecast Outcomes (2020)
Hendrik Bessembinder
SSRN Working Paper, URL

The fifth of seven AGNOSTIC Papers on the extreme concentration in stock markets. This one will finally examine how to identify the few big winners ex-ante (at least it will try). Future winners have some distinct fundamental characteristics today. That said, the picture remains noisy and it’s very difficult to find them systematically…

  • Future top-performers tend to be younger, produce higher drawdowns, and spend more on R&D
  • Future wealth-creators tend to be older, more levered, and pay higher dividends
  • Identifying big winners remains challenging

AgPa #13: Concentrated Stock Markets (4/7)

Extreme Stock Market Performers, Part III: What are their Observable Characteristics? (2020)
Hendrik Bessembinder
SSRN Working Paper, URL

The fourth of seven AGNOSTIC Papers about the extreme concentration in stock markets. This one goes one step further and examines the fundamental characteristics of big winners ex-post. The main insight is quite intuitive: outstanding stock performance usually comes with outstanding fundamental performance of the underlying company…

  • Big winners grow faster, are more profitable, and have smaller drawdowns
  • Observable fundamentals still explain relatively little

AgPa #12: Concentrated Stock Markets (3/7)

Extreme Stock Market Performers, Part II: Do Technology Stocks Dominate? (2020)
Hendrik Bessembinder
SSRN Working Paper, URL

The third of seven AGNOSTIC Papers about the extreme concentration within stock markets. This one examines the industry composition of the most and least successful companies between 1950 and 2019 in the US. Unfortunately, just looking at industries is not really helpful to identify the few big winners…

  • The Tech-Industry is not as dominant as it seems at first glance
  • There is (unfortunately) not “the one” industry to look at

AgPa #10: Concentrated Stock Markets (1/7)

Do stocks outperform Treasury bills? (2018)
Hendrik Bessembinder
Journal of Financial Economics 129(3), 440-457, URL

I try to be careful with superlatives, but I think that this week’s AGNOSTIC Paper(s) are a must-read for everyone seriously interested in stock markets.

A few very successful companies drive the entire US market while the majority of stocks underperform even risk-free treasuries. Moreover, the most frequent lifetime return for U.S. companies is -100%. Those brutal empirical facts have strong implications for investors.

AgPa #5: The Return on Everything

The Rate of Return on Everything, 1870–2015 (2019)
Òscar Jordà, Katharina Knoll, Dmitry Kuvshinov, Moritz Schularick, Alan M. Taylor
The Quarterly Journal of Economics 134(3), 1225-1298, URL

This week’s AGNOSTIC Paper is a deep dive into financial history. The authors estimate the total return of equity, housing, bonds, and bills in 16 advanced economies for the period from 1870 to 2015.

The paper is very comprehensive and I focused on the issues that are (in my opinion) most interesting for investors:

  • Real returns on risky assets were 7-8% from 1870 to 2015
  • Returns on risky assets were substantial but volatile
  • Realized risk premiums fluctuate widely across time and countries
