Talk 1: **Analyzing FOMC press conferences using video recordings**

Abstract:

This talk will be about harvesting information in unconventional data such as video images in order to forecast the equity market. I will argue that the behaviour of the President of the Federal Reserve (Fed) captured on camera during important meetings can be used to extract a new generation of signals. Specifically, I propose a new tool to characterize the resolution of uncertainty around the Federal Open Market Committee (FOMC) press conferences. It relies on the construction of a measure capturing the level of discussion complexity between the Fed Chair and reporters during the Q&A sessions. I show that complex discussions are associated with higher equity returns and a drop in realized volatility. The method creates an attention score by quantifying how much the Chair needs to rely on reading internal documents to be able to answer a question. This is accomplished by building a novel dataset of video images of the press conferences and leveraging recent deep learning algorithms from computer vision.

**Note** that this talk is unrelated to Alexis' current employer and what Alexis is doing at his current job. The presentation covers previous work done during his PhD. This work was presented publicly at several academic and semi-academic conferences in Europe.

Speaker bio:

Alexis Marchal is a quantitative researcher in one of the largest sovereign wealth fund. He has received a master degree from the university of Geneva and a PhD from the Swiss Federal Institute of Technology in Lausanne and the Swiss Finance Institute. His main research interests are at the intersection of machine learning, asset pricing, and alternative data. Notably, he has worked on applications of Natural Language Processing and Computer Vision to financial markets.

Talk 2: **Hierarchical PCA: Incorporate (fundamental) priors into PCA**

(a tribute to the late Marco Avellaneda)

Abstract:

PCA is a useful tool for quant trading (stat arb) but in its naive implementation suffers from several forms of instabilities which yield to unnecessary turnover (trading cost...) and spurious trades.
In order to regularize the model, several techniques are available.
We will discuss one in particular: The Hierarchical PCA (HPCA).
With HPCA, we modify the empirical correlation matrix such that it incorporates information from a prior (fundamental) hierarchical classification: For example, sectors and industries for stocks and bonds; protocols, layers and use cases for cryptos.
We will illustrate this presentation with some basic python code and results comparing PCA and HPCA for stocks and cryptos.

**Note** that this talk is unrelated to Gautier's current employer and what Gautier is doing at his current job. The presentation covers material published by Marco Avellaneda in the paper *Hierarchical PCA and Applications to Portfolio Management* https://arxiv.org/abs/1910.02310.
