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.

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.

Title

A Tale of Two Tails: Size, Volatility and Uncertainty

Abstract

We derive the firm’s equity valuation mainly by focusing on the two tails that involve optionality. The equity shareholders possess two call options on the firm’s equity value. An upside potential benefit call and a downside risk protection call represent these two tails of the firm. An optimal capital structure could be derived from these two classes of call options. Navigate the SIZE and Volatility portfolios show resulting significant effects on the tails. Furthermore, we show that they are highly significantly correlated with uncertainty indices such as EPU and/or VIX.

Title: “Stoptions”

Abstract

We introduce a new derivative security called a stoption. After paying an upfront premium, the owner of a stoption accrues realized price changes in some underlying security until the flow is stopped by the owner. Upon stopping, the reward is the sum of all of the previous price changes plus a deterministic amount which can vary with the stopping time. Stoptions are finite-lived and hence must be stopped at or before a fixed maturity date. We propose dynamics under which we can determine the optimal stopping strategy and value the stoption premium in closed-form. We also present an application to DVA (debit valuation adjustment) under full collateralization.

Title

Can We Still Blame MBS Hedgers?

Abstract

Part of fixed-income folklore is the idea that directional moves in the rates markets can get exaggerated by the duration-rebalancing decisions of mortgage-backed security (MBS) investors and market-makers.  Under stable regimes, we could posit that this theme resides in the market’s “background noise.”  In those backdrops, there’s a consensus toolkit for interpreting its effect and how it fits with other price drivers.  In periods of harder-to-rationalize repricings in rates space this “convexity effect” attracts more attention:  The risk attributes (such as the distribution across the coupon “stack”) of the outstanding “stock” of MBSs and the sector’s relative value are major determinants of the rebalancing strategy, and thus of the effect’s magnitude.

The advent of the Fed’s quantitative easing (QE) programs (currently taking $40 billion of agency MBSs out of private hands per month, net of principal redemptions) and the continuing sell-down of GSE’s balance sheets mean that there’s a significantly reduced amount of MBS paper held by “players who hedge.”  Can we still blame the MBS hedgers when we experience greater-than-expected rates volatility?

Title

Option-Implied Semimartingale Characteristics

Abstract

We propose nonparametric methods for the recovery of the spot semimartingale characteristics of an asset price from noisy short-dated option data. The estimation is based on forming portfolios of options with different strikes that replicate the (risk-neutral) conditional characteristic function of the underlying price in a model-free way. The recovery of spot volatility is done by making use of the dominant role of the volatility in the conditional characteristic function over short time intervals and for large values of the characteristic exponent. The estimation of the tail jump variation measures, on the other hand, is based on their representation as integrals of the Laplace transforms of the jump compensator. The latter are in turn recovered from the second derivative of the option-implied characteristic function estimate, de-biased by its value at high frequencies to account for the diffusive volatility. We apply the estimation techniques to real data and illustrate the use of the extracted option-implied semimartingale characteristics in asset pricing applications.

Title

In Pursuit of Samuelson: Studies of Commodity Volatilities and Correlations

Abstract

Empirical analysis of price returns is an essential component in the valuation methods in any asset class. Energy commodities present unique challenges: seasonality and inventory are crucial for covariance structure; forward price volatility increases dramatically while approaching contract’s expiration: the famous Samuelson effect; liquidity in commodity futures and options liquidity is concentrated at short tenors.

This fact makes the term structure of volatility and correlations very important in pricing and hedging decisions. In this presentation, I give the results of my work with NYU students devoted to this subject. We will follow three goals:

  • Parameterization of Samuelson effect and the calibration procedures for commodities futures, including seasonal commodities as gas and power.
  • Samuelson effect for commodity correlations, parameterizing calendar correlations.
  • Contrast between the traditional Black and its long-ago predecessor Bachelier model in view of recent dramatic events in oil markets in Spring 2020.

Bio

Roza Galeeva has extensive experience of over 18 years with commodity derivatives – modelling, pricing, and risk management. She has been employed at senior levels as a quant at Williams Energy, Northeast Utilities, and most recently, for 13 years, 2005-2018 at Morgan Stanley. She worked at MS in different roles and departments, including the Valuation Group, and later the MS strats and modelling group. Prior to the industry, Roza was teaching courses in mathematics in different countries. She has a PhD from Moscow State University in Mathematical Physics. She published papers in geometry, PDE, dynamical systems, and financial engineering. She made her come back to academia in 2017 at NYU with teaching courses in financial engineering and working with NYU students on research projects on Commodity Derivatives.

Title: “Some Applications of Machine Learning in Finance”

Abstract

Finance has always tried to make use of all available information to optimize investment decisions. The advent of efficient Machine Learning algorithms, alternative data, and computational powers has deeply impacted many fields in finance. To mention a few, rotation of factors according to market regimes in factor investing, option pricing and hedging, anomaly detection, covariance matrix cleaning, transaction cost analysis. Alternative data include texts from news and tweets, supply chain data, satellite images, vessel routes, weather data, credit card transactions, geolocation data.

This overflow of information opens the door to endless number crunching and apophenia. The desperate search for a signal leads to overfitting and unstable relationships, so beware. As I like to say, the market is a machine made to destroy the signal!
