The arbitrage pricing theory (APT) attributes differences in expected returns to exposure to systematic risk factors, which are typically assumed to be strong. In this paper we consider two aspects of the APT. Firstly we relate the factors in the statistical factor model to a theoretically...

Algorithmic trading, so popular nowadays, uses many strategies that are algorithmizable and promise profitability. This research answers the question whether it is possible to successfully use a convexity arbitrage strategy in a bond portfolio in financial practice. It should provide a positive...

Focusing on capital asset returns governed by a factor structure, the Arbitrage Pricing Theory (APT) is a one-period model, in which preclusion of arbitrage over static portfolios of these assets leads to a linear relation between the expected return and its covariance with the factors. The APT,...

How can we assess whether macro-prudential regulations are having their intended effects? If these regulations are optimal, their marginal benefit of addressing externalities should equal their marginal cost of distorting risk-sharing. These risk-sharing distortions will manifest as trading...

Trading algorithms are an integral component of modern asset markets. In two experimental markets for long-lived correlated assets we examine the impact of alternative types of arbitrage-seeking algorithms. These arbitrage robot traders vary in their latency and whether they make or take market...

The article describes a global and arbitrage-free parametrization of the eSSVI surfaces introduced by Hendriks and Martini in 2019. A robust calibration of such surfaces has already been proposed by the quantitative research team at Zeliade in 2019, but it is sequential in expiries and lacks of...

Theory suggests that traders will be more reluctant to trade on negative private information about an ongoing merger if their trading will cause the merger to be canceled. This paper provides evidence on the existence of such endogenous limits to arbitrage and it's consequence on the...

The prices of exchange-traded funds (ETFs) can deviate significantly from their net asset values (NAVs). Exploiting such inefficiencies is often too costly because it involves taking positions in hundreds of underlying illiquid securities. We develop a method that identifies a liquid mimicking...

‘’Blockchain’’ is often described as a technology that allows the prevention of conflicts. The code is thus presumed to accurately execute the will of the parties. However, blockchain technology supports economic and social interactions between humans and, as in any social environment,...

I generalize the textbook arbitrage-pricing framework to characterize how uninformative flows generate price impacts. The modeled channel is that price impacts arise as marginal investors' risk compensation. I build a new model of price impacts that allows for common factors of flows and common...

In this paper we are concerned with the role of factor strength and pricing errors in asset pricing models, and their implications for identification and estimation of risk premia. We establish an explicit relationship between the pricing errors and the presence of weak factors that are...

This paper examines the implications of pricing errors and factors that are not strong for the Fama-MacBeth two-pass estimator of risk premia and its asymptotic distribution when T is fixed with n → ∞, and when both n and T → ∞, jointly. While the literature just distinguishes strong and...

Purpose - Nowadays popular algorithmic trading uses many strategies which are algoritmizable and promise profitability. This research assess if it is possible successfully use interest rates sensitivity arbitrage in bond portfolio (also known as convexity arbitrage) in financial praxis. This...

This paper aims to carry out a preliminary analysis of the arbitrage pricing theory in Argentine capital market, with special emphasis on inflation as a variable of interest for an emerging country, an underdeveloped financial market, and a period under analysis with inflationary trends and...

Modelling joint dynamics of liquid vanilla options is crucial for arbitrage-free pricing of illiquid derivatives and managing risks of option trade books. This paper develops a nonparametric model for the European options book respecting underlying financial constraints and while being...

The Svensson generalization of the popular Nelson-Siegel term structure model is widely used by practitioners and central banks. Unfortunately, like the original Nelson-Siegel specification, this generalization, in its dynamic form, does not enforce arbitrage-free consistency over time. Indeed,...

The no Butterfly arbitrage domain of Gatheral SVI 5-parameters formula for the volatility smile has been recently described. It requires in general a numerical minimization of 2 functions altogether with a few root finding procedures. We study here the case of some sub-SVIs (all with 3...

The European Union's push towards market-based procurement of redispatch services has sparked fears of so called Inc-Dec-Gaming, i.e. the incentive to engage in arbitrage between the national wholesale market and the local redispatch market. The latter would increase both likelihood and severity...

A natural liquidity mismatch emerges when liquid exchange traded funds (ETFs) hold relatively illiquid assets. We provide a theory and empirical evidence showing that this liquidity mismatch can reduce market efficiency and increase the fragility of these ETFs. We focus on corporate bond ETFs...

This paper studies the implications of arbitrage in a large asset market under conditions of (Knightian) uncertainty.First, I adapt the notion of arbitrage to a market in which the assets' returns are affected by uncertainty across probability distributions. The setting delivers the analog of...

This study applies the Caginalp & Balenovic (1999) model for asset flow dynamics to fully collateralized stablecoins. The analysis provides novel insights on how trend-reversion and reactions to peg deviations work together to keep stablecoin prices close to the price they are targeting. A...

A central conjecture of behavioural finance is that arbitrage opportunities appear as a result of systematic irrational investment behaviour and persist since real-world arbitrage trades actually involve costs and risks due to market frictions and non-fundamental risk. This paper shows that the...

Classical wealth management heavily relies on the linear and two-dimensional world of Modern Portfolio Theory. While this has generally worked for investors, many new investment offerings only inadequately map into the CW world. This inadequacy is a source of potentially large investor losses,...

I show that an important no-arbitrage consistent but costly collateral rental yield contributes to about two-thirds of the standard CIP violations. I measure this yield using two approaches applied to short- and long-term CIP horizons. First, I assume that the yield is observable and proxy it...

We study the dynamics of cash-and-carry arbitrage using the U.S. crude oil market. Sizable arbitrage-related inventory movements occur at the NYMEX futures contract delivery point but not at other storage locations where, instead, operational factors explain most inventory changes. We add to the...

This study outlines an affine term structure model (ATSM) of TIPS that decomposes yields into real expected rates, real term premiums, and liquidity premiums. The estimation incorporates an observable liquidity factor that more comprehensively captures limits to arbitrage implied by yield curve...

This paper is an attempt to study fundamentally the valuation of insurance contracts. We start from the observation that insurance contracts are inherently linked to financial markets, be it via interest rates, or – as in hybrid products, equity-linked life insurance and variable annuities –...

We study a segmented-markets setting in which self-fulfilling volatility can arise. The only requirements are (i) asset price movements redistribute wealth across markets (e.g., equities rise as bonds fall) and (ii) some stabilizing force keeps valuation ratios stationary (e.g., cash flow growth...

In a one price economy, the Fundamental Theorem of Asset Pricing (FTAP) establishes that no-arbitrage is equivalent to the existence of an equivalent martingale measure. Such an equivalent measure can be derived as the normal unit vector of the hyperplane that separates the attainable gain...

An extension of Merton’s (1974) model (EMM) taking account of the firm’s payments and generating a new statistical distribution for the firm value is suggested. In an open log-value space, this distribution evolves from the initially normal to negatively skewed one. When payments are zero or...

Arbitrageurs with a short investment horizon gain from accelerating price discovery by advertising their private information. However, advertising many assets may overload investors' attention, reducing the number of informed traders per asset and slowing price discovery. So arbitrageurs...

We use a no-arbitrage term structure model of equity yields computed from the prices of dividend swaps to estimate the yields on hypothetical bonds with cash-flows indexed to the level of US GDP. This provides a novel approach for estimating the possible relative cost of conventional and...

Rational frictionless asset pricing models imply that inflation swap rates and break-even inflation rates with same maturity must be equal. The data, however, suggest a persistent positive difference between these two quantities, which the literature attributes to mispricing of Treasury...
