AgPa #25: The Economics of High-Frequency-Trading

The Economics of High-Frequency Trading: Taking Stock (2016)
Albert J. Menkveld
Annual Review of Financial Economics, Vol. 8, 1-24, URL/SSRN

This week’s AGNOSTIC Paper examines once again a somewhat controversial topic: high frequency trading. The (public) image of HFTs is quite mixed with a clear tendency towards negative. However, an open-minded and scientific analysis suggests that we are probably better off with HFTs than without them…

  • Trading costs strongly decreased between 2001 and 2011
  • HFTs are fast, well-informed, and often market makers
  • Order-preying and arm’s races – it’s not all good
  • The benefits seem to outweigh the costs

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 #19: ESG Confusion (2/2)

Aggregate Confusion: The Divergence of ESG Ratings (2022)
Florian Berg, Julian F. Kölbel, Roberto Rigobon
Review of Finance, Corrected Proof, 1-30, URL

The second AGNOSTIC Paper on the confusion around ESG. This one examines the disagreement of ESG ratings in much more detail and provide some explanations why they are so different…

  • ESG ratings disagree: the average correlation is just 0.54
  • 709 indicators and 64 categories: no wonder that there is disagreement
  • Most disagreement comes from “measurement” and “scope”
  • There is a “rater effect” for ESG ratings

AgPa #16: Concentrated Stock Markets (7/7)

Mutual Fund Performance at Long Horizons (2022)
Hendrik Bessembinder, Michael J. Cooper, Feng Zhang
SMU Cox School of Business Research Paper No. 22-11 via SSRN, URL

The seventh and final AGNOSTIC Paper on the extreme concentration in stock markets. This one is an out-of-sample test and documents very similar concentration and positive skewness for US mutual funds between 1991 and 2020.

  • Longer investment-horizons lead to extremer return distributions – also for mutual funds
  • Most active managers underperform passive benchmarks – especially over the long-term
  • Compared to the S&P 500, mutual fund investors lost about $1.3T between 1991 and 2020

But a picture is worth a thousand words…

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 #11: Concentrated Stock Markets (2/7)

Long-Term Shareholder Returns: Evidence from 64,000 Global Stocks (2021)
Hendrik Bessembinder, Ta-Feng Chen, Goeun Choi, K.C. John Wei
SSRN Working Paper, URL

The second of seven AGNOSTIC Papers about the extreme concentration within stock markets. This one goes beyond the US and examines global stock markets between 1990 and 2020. The pattern of extreme concentration is very similar for 41 countries beside the US and in some cases even stronger.

  • Longer investment-horizons lead to extremer return distributions – also outside the US
  • Just 2.4% of all companies created the entire net wealth in global stock markets
  • All stock markets are concentrated but there are regional differences

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

AgPa #4: Measuring the World’s Assets (2/2)

Historical Returns of the Market Portfolio (2019)
Ronald Doeswijk, Trevin Lam, Laurens Swinkels
The Review of Asset Pricing Studies 10(3), 521-567, URL

This is the second post on the global market portfolio and again examines two papers. It is designed to be a sequel, so I recommend to read the first part before.

The global market portfolio is a tough empirical challenge. Different methodology leads to different results and the papers disagree on several points. But there are some common insights that enhance our understanding of the market portfolio.

  • Most assets are not publicly traded
  • Stock markets are relatively small
  • Recent historical returns were 4.4% to 6.3% per year
  • The market portfolio is a good starting point

AgPa #3: Measuring the World’s Assets (1/2)

The Global Market Portfolio (2021)
Gregory Gadzinski, Markus Schuller, Andrea Vacchino
The Journal of Portfolio Management 47(8), 151-163, URL

This week’s AGNOSTIC Paper attempts to translate an important theoretical concept into practice – the global market portfolio.

The global market portfolio captures all available assets and each is weighted by its market value. The authors develop two proxies for this portfolio and present some interesting insights:

  • Global assets were worth about $667T in 2019
  • The investable market portfolio returned 4.7% p.a. from 2005-2020/Q1
  • The non-investable market portfolio returned 5.9% p.a. from 2005-2020/Q1
