Title

A Brief History of Quant Investing – from Traditional Equity Factors to Machine Learning

Abstract

Over the past few decades, systematic quantitative investing has gathered interest from a wide range of investors ranging from hedge funds to asset owners. In this presentation, we review a few of the most emblematic systematic strategies, and discuss their more recent implementations making use of modern statistical learning. Differences in performance across factors and cycles highlight the importance of having a portfolio framework. We show how diversification can be a factor of performance in that field too.

Title

The Contribution of Frictions to Expected Returns: An Options-based Estimation Approach

Abstract

We document that properly scaled deviations from put-call parity estimate the contribution of market frictions to expected returns (CFER) accurately, by means of a nonparametric theoretically founded identification strategy. The required conditions are that our estimator predicts the underlying but not the synthetic stock’s return. The data satisfy the two conditions; the alphas of the estimated CFER-sorted spread portfolios are up to 1.86% per month. The estimated CFER covaries non-linearly with proxies of market frictions. An agent-based equilibrium model explains our findings; alphas can be twice as big as the round-trip transaction costs, thus corroborating the accuracy of our estimator.

Title

The Microstructure of Cointegrated Assets

Abstract

I will present a generalization of the micro price to multiple assets. This yields a notion of fair prices, as a function of the observable state of multiple order books. I will show how to compute the microprices of two highly cointegrated assets, using Level-1 data collected on Interactive Brokers. I will then test the model by designing an execution algorithm based on this two-dimensional microprice and show that it can save half of the bid-ask spread cost.

He is a Senior Research Associate at Cornell Financial Engineering Manhattan (CFEM) and was a VP of High Frequency Trading at Cantor Fitzgerald.

Title

The Impact of Collateral and Stays on Financial Stability

Abstract

We study the spread of losses and defaults in financial networks with two features: collateral requirements and resolution and bankruptcy stay rules. When collateral is committed to a firm’s counterparties, a solvent firm may default if it lacks sufficient liquid assets to meet its payment obligations. Collateral requirements can thus increase the risk of contagion. Moreover, one firm may benefit from the failure of another if the failure frees collateral committed by the surviving firm, giving it additional resources to make other payments. Contract termination at default may also similarly improve the ability of other firms to meet their obligations. As a consequence of these features, the timing of payments and collateral liquidation must be carefully specified to establish the existence of payments that clear the network. Using this framework, we show that committed collateral in the form of initial margin in over-the-counter derivatives markets may increase contagion and financial instability. We also compare networks under different stay rules in OTC markets. Our analysis shows that when firms are not highly leveraged in terms of derivatives transactions, full contract termination may reduce contagion.
