On convergence of a pure factor portfolio model

Ely Klepfish
Director Quant Aspect

and

Julien Riposo
Quant

Pure factor portfolios, with exposure one to their own factors and zero otherwise, are derived in a sequence of two-step iterations alternating between multivariate cross-sectional and time-series regression. A criterion for convergence to a state of consistency between the two regressions is identified and is shown to be crucial for rigorous factor risk attribution.  A proof of convergence of the sequential derivation is presented.

Portfolio Market Impact

Costis Maglaras
Dean; David and Lyn Silfen Professor of Business – Columbia Business School
and
Ryoko Ito
Executive Director
Goldman Sachs International

Using a unique data set that pools all of Goldman Sachs’ US equities algorithmic trading activity we construct the net portfolios executed in successive 15 min intervals, and use these portfolio trades to estimate market impact. We examine how random (drift-less) price fluctuations in the discrete limit order book market contribute to execution costs, and subsequently estimate that effect which we find to be statistically significant and economically meaningful.  We characterize impact decay we see in that data set, and discuss implications on optimal execution.

Authors: Costis Maglaras (Columbia Business School, Columbia University), Michael Steliaros (Goldman Sachs, Global Markets), Ryoko Ito (Goldman Sachs, Global Markets)

Towards Net Zero!

Katharina Schwaiger
Executive Director
Blackrock

Climate change is “widespread, rapid, and intensifying” according to the most recent Sixth Assessment (AR6) report of the Intergovernmental Panel on Climate Change (IPCC, 2021), a United Nations body representing 195 member governments for assessing the science related to climate. In this talk we explore how investors can align their investments with the climate goals of the Paris Agreement – aiming to limit the global temperature increase to well below two degrees. We build systematic portfolios using new datasets such as the Science Based Targets Initiative (SBTi) and TRACE across equity and fixed income strategies that are both return enhancing as well as being climate-aware.

Macro Factor Investing with Style

Harald Lohre
Director of Research
Invesco Quantitative Strategies

Investors face similar macroeconomic risks and opportunities regardless of their individual investment preferences. To best navigate growth and inflation concerns, we propose building macro factor-mimicking portfolios diversified across asset classes and style factors. We focus on the macro factors Growth, Inflation and Defensive. Our approach allows for shaping the macroeconomic risk exposure of a given portfolio by applying systematic macro factor completion to effectively address specific economic outcomes.

Optimal portfolio implementation: The role of market impact and crowding in style-factor and ESG portfolios

Michail Steliaros
Managing Director
Goldman Sachs International
and
Giuliano De Rossi
Executive Director
Goldman Sachs International

In the first part of the presentation we analyse the cost of trading factor strategies using a market impact model estimated from actual transactions data, realistic and multiple portfolio construction techniques and up-to-date data. Our results suggest that, for realistic portfolio sizes, the typical costs of rebalancing factor strategies are unlikely to erode the factor premium.
In addition, by building portfolios across different factors and with alternative portfolio construction techniques over time, we are able to assess the degree of similarity amongst strategies, which can be viewed as a measure of crowding. The properties of our new crowding indicator are illustrated through an extensive empirical investigation.
In the second part of the talk, using the same models of market impact, we tackle a question that has thus far been mostly ignored: How does an ESG tilt affect portfolio liquidity and trading costs? Our results suggest that high-ranking ESG stocks tend to be more liquid than the rest of the universe, even after taking into account the fact that large companies tend to have higher ESG scores. Using the GS SUSTAIN scores from Goldman’s Global Investment Research (GIR), we simulate a number of strategies that add an ESG tilt to the major global indices. In addition, we analyse the cost of trading futures contracts as an alternative method of gaining exposure to this theme. Our results show that it is possible to boost the ESG profile of a portfolio, whilst mitigating market impact, through optimisation. The magnitude of the estimated transaction costs is not large enough to generate a significant drag on the recent outperformance of ESG stocks.

Central Bank digital currencies

Brunello Rosa
CEO
Rosa & Roubini Associates

Digital currencies are becoming increasingly present on both research and policy agendas, including for central banks. This event explores the rise of CBDCs as a new form of payment system, able to compete with cryptocurrencies and stablecoins. The Brunello will argue that CBDCs could be useful as a means for central banks to record transactions in an increasingly cashless economy and could help improve central banks’ monetary transmission. The event will also discuss the geopolitical role of central bank digital currencies, with a particular focus on China and the risk of cyber-attacks associated with that.
