Title: The Rise of the Retail Trader – Estimating Retail Activity using Public Trading Data

The “Game Stop frenzy” and the broader “meme stock” phenomenon that has developed over the last year have prompted many questions from clients on how to effectively estimate retail activity. To address these questions, we have developed a model using publicly available data. Our model seeks to estimate both the level and direction of retail trading activity (i.e., how much of the daily trading volume in each stock is attributable to retail traders, and whether they were net buyers or sellers of that volume).
We find that insights into retail activity provided by our model can be used to generate alpha. We see a positive relationship between our estimate of the retail order imbalance and the subsequent stock returns. Stocks with a high buy imbalance tend to outperform stocks with a high sell imbalance over the subsequent one month. The signal can be further amplified by limiting the universe of stocks to those with high retail activity.

Title: Optimal Execution with Quadratic Variation Inventories
We describe and implement statistical tests arguing for the presence of a Brownian component in the inventories and wealth processes of individual traders. Using intra-day data from the Toronto Stock Exchange, we provide empirical evidence of this claim. Both for regularly spaced time intervals, as well as for asynchronously observed data, the tests reveal with high significance the presence of a non-zero Brownian motion component. Furthermore, we extend the theoretical analysis of an existing optimal execution model to accommodate the presence of Ito inventory processes, and we compare empirically the optimal behavior of traders in such fitted models, to the actual behavior read off the data.

Title: SEC EDGAR Filings Over the Years: Where Is Alpha Today? (Joint work with Bojun Li, Cornell University)
SEC Edgar data was launched in 1984 as a convenient way to widely distribute information on publicly-traded companies. With the proliferation of machine learning and data science techniques, mining EDGAR has never been easier. This has indeed translated into market efficiency. In this research, we explore various alpha components of EDGAR over the years and show that, even though the alpha from EDGAR has become much harder to mine, the inefficiencies still exist and the filings still carry useful information for market practitioners.

Title: Libor Transition: Looking Forward to Backward-Looking Rates


In this talk, we define and model forward risk-free term rates, which appear in the payoff definition of derivatives and cash instruments, based on the new interest-rate benchmarks that will be replacing IBORs globally. We show that the classic interest-rate modeling framework can be naturally extended to describe the evolution of both the forward-looking (IBOR-like) and backward-looking (setting-in-arrears) term rates using the same stochastic process. We then introduce an extension of the LIBOR Market Model (LMM) to backward-looking rates. This extension, which we call generalized forward market model (FMM), completes the LMM by providing additional information about the rate dynamics between fixing/payment times, and by implying dynamics of forward rates under the classic money-market measure. Our FMM formulation is based on the concept of extended zero-coupon bonds, which proves to be very convenient when dealing with backward-looking setting-in-arrears rates. Thanks to this, not only the bonds themselves, but also the forwards and swap rates, along with their associated forward measures, can be defined at all times, even those beyond their natural expiries.
Finally, we complete the FMM by embedding into a Markovian HJM to allow for the generation of any forward-looking or backward-looking rates, and hence for the pricing of any exotic payoff or derivatives portfolio.

Title: Multilayer heat equations: Application to finance (joint work with Alex Lipton and Dmitry Muravey)


In this paper, we develop a Multilayer (ML) method for solving one-factor parabolic equations. Our approach provides a powerful alternative to the well-known finite difference and Monte Carlo methods. We discuss various advantages of this approach, which judiciously combines sei-analytical and numerical techniques and provides a fast and accurate way of finding solutions to the corresponding equations. To introduce the core of the method, we consider multilayer heat equations, known in physics for a relatively long time but never used when solving financial problems. Thus, we expand the analytic machinery of quantitative finance by augmenting it with the ML method. We demonstrate how one can solve various problems of mathematical finance by using our approach. Specifically, we develop efficient algorithms for pricing barrier options for time-dependent one-factor short-rate models, such as Black-Karasinski and Verhulst. Besides, we show how to solve the well-known Dupire equation quickly and accurately. Numerical examples confirm that our approach is considerably more efficient for solving the corresponding partial differential equations than the conventional finite difference method by being much faster and more accurate than the known alternatives.

Title: Taxation Channels and Municipal Bond Yield Spreads


I analytically model and empirically examine how through property, income, and sales tax channels, household income and housing wealth permeates onto municipal bonds spreads. Theoretically, higher wages should attenuate yield spreads, especially through income and sales tax channels. Consistent with analytical predictions, household income attenuates yield spreads through sales and income tax channels. In theory, rising housing prices only narrow spreads if sales taxes due to housing wealth effect exceed the after-tax cost of mortgaging the housing wealth. Predictably, housing wealth attenuates yield spreads through property tax channel. Unpredictably though, household income also narrows spread through a pronounced property tax channel. Also unpredictably, housing wealth narrows spreads through sales and income tax channels. Counter theoretically, both household income and housing wealth extenuate yield spreads. Outside interactions with wages and housing wealth, none of local/state level taxes have standalone impacts on municipal yield spreads.

Title: Towards Non-Perturbative Finance: How Quantitative Finance can benefit from insights from Reinforcement Learning and Physics
In this talk, I will discuss non-linear models of market dynamics originating from the presence of market flows and frictions. Viewing these dynamics as decision making by external investors along the lines of the reinforcement learning methods, and using ideas from quantum mechanics, one ends up with a tractable non-linear model for the dynamics of the market or a single stock which is able to capture both benign and crises regimes (or alternatively regimes of small and large fluctuations). The resulting model is able to accurately match the market prices of options using a single volatility parameter, which stands in stark contrast to most of the models in the literature that usually consider more complicated models of noise such as local, stochastic or rough volatility models.

Title: Dual-Primal Simulation Algorithm for Pricing American Options


Pricing American options is one of the most classical problems of quantitative finance. In this talk, we present a novel simulation-based algorithm to this classical problem using deep learning techniques. In the standard primal-dual approach, one starts with finding the optimal strategy (primal) from cross-sectional regression and then extracting the martingale component (dual) from the corresponding value function. Instead, we propose a dual-primal approach. We start by solving the dual problem directly where replication martingales are parameterized by a neural network and optimized through the minimization of residual risk. The same neural network is applied to the temporal data at each time step so that the evaluation and training of the network can be done in a highly efficient time-distributed fashion. Then an exercise strategy can be constructed from the estimated optimal martingale by solving a classification problem. Both problems can be solved efficiently without relying on recursive schemes commonly used in such problems. In addition, the hedges obtained from the dual problem significantly reduce the variances of both lower and upper bound estimates and produce accurate confidence interval for the true price.

Title: Optimal Barrier Trading With and Without Transaction Costs


Utility optimization with distributions of returns that more accurately reflect the reality of market data indicate optimal portfolios should be non-linear functions of the alpha in the absence of transaction costs. A simple limiting case that involves positions that are only long, short, or flat is suggested by these results. For that limiting case it is possible to derive Sharpe Ratio maximizing solutions for an active trader that, functionally, resemble signal processing systems with hysteresis that are understood in a that context to be filters that reduce “jitter” around threshold crossings.

Title: Banking through Climate Change: Climate Risk and Opportunity


“Changes in climate policies, new technologies and growing physical risks will prompt reassessments of the values of virtually every financial asset. Firms that align their business models to the transition to a net zero world will be rewarded handsomely. Those that fail to adapt will cease to exist.” [Mark Carney, Chair of the Financial Stability Board and Governor of the Bank of England]. Banks play a critical role in financing the transition toward a net zero economy, and the world’s banking regulators are putting climate risk at the top of the agenda. In this talk, we will define climate risk, and discuss how banks identify, measure, monitor and manage the financial risks posed by climate change. This includes climate risk in pricing and valuing assets and climate risk from the transition to a low-carbon, clean energy economy. We will review the range of methodologies available for assessing climate risks and opportunities and focus on stress testing/scenario analysis and risk models that have taken center stage. Finally, we will take a closer look at the regulatory trends shaping the management of climate change risks in the financial industry in the United States and around the world, now and in decades to come.

Title: The decommissioning of LIBOR and its replacement by SOFR


In the wake of the 2008 financial crisis and the LIBOR scandals of early 2010s, it became obvious for regulators that LIBOR rates were not a suitable benchmark on which to index most of the interest rates transactions. LIBOR had to be decommissioned; and as early as 2017, SOFR, its replacement, was selected by the ad-hoc Alternative Reference Rates Committee.

We are today at a turning point. After five year of transition, SOFR has become the new market standard and LIBOR only has a year left. Which brings us to two fundamental questions:

  1. What are the differences between LIBOR and SOFR and their implications in the pricing of derivatives?
  2. What will happen to the $200 trillions of LIBOR-based transaction still existing today?

To answer these questions, we will first examine the reasons why LIBOR was decommissioned and the way SOFR was conceived not to reproduce the same mistakes. After a brief refresher on the most common interest rates derivatives we will then analyze what it means to price new products in a SOFR world and how to deal with old LIBOR trades.
