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.

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!

He has been applying Machine Learning to a variety of problems in Finance and has given many lectures on the topic in the Americas, Europe, and Asia over the past few years.

“Lightning Talk” Info:

CFEM alumna Yumeng Ding will discuss her team capstone project, which was titled, “Interpreting Machine Learning Models.” By utilizing Machine Learning interpretability models, the Cornell CFEM team, sponsored by Alliance Bernstein, explored how black-box models can be explained and evaluated in finance. The team analyzed S&P 500 constituents and explored the interpretability of some widely-used ML modes.

Yumeng Ding (MFE Cornell ’20, BA Finance Fudan University‘15) is a soon-to-be analyst in Strategic and Analytics at Deutsche Bank.

Title

Fourier-based methods for the management of complex insurance products

Abstract

This paper proposes a framework for the valuation and the management of complex life insurance contracts, whose design can be described by a portfolio of embedded options, which are activated according to one or more triggering events. These events are in general monitored discretely over the life of the policy, due to the contract terms. Similar designs can also be found in other contexts, such as counterparty credit risk for example.

The framework is based on Fourier transform methods as they allow to derive convenient closed analytical formulas for a broad spectrum of underlying dynamics. Multidimensionality issues generated by the discrete monitoring of the triggering events are dealt with efficiently designed Monte Carlo integration strategies. We illustrate the tractability of the proposed approach by means of a detailed study of ratchet variable annuities, which can be considered a prototypical example of these complex structured products.

This is joint work with Ernst Eberlein, Thorsten Schmidt and Raghid Zeineddine.
