Instantaneous Arbitrage and the CAPM
Nielsen, Lars Tyge - 2019
This paper studies the concept of instantaneous arbitrage in continuous time and its relation to the instantaneous CAPM …. Absence of instantaneous arbitrage is equivalent to the existence of a trading strategy which satisfies the CAPM beta pricing … relation in place of the market. Thus the difference between the arbitrage argument and the CAPM argument in Black and Scholes …

Put Option Exercise and Short Stock Interest Arbitrage
Barraclough, Kathryn - 2013
U.S. exchange-traded stock options are exercisable before expiration. While put options should frequently be exercised early to earn interest, they are not. In this paper, we explain an early exercise decision rule and then examine actual exercise behavior during the period January 1996 through...

Beta risk in the cross-section of equities
Boloorforoosh, Ali; Christoffersen, Peter F.; Fournier, … - 2017
We develop a conditional capital asset pricing model in continuous-time that allows for stochastic beta exposure. When beta co-moves with market variance and the stochastic discount factor (SDF), beta risk is priced, and the expected return on a stock deviates from the security market line. The...

Understanding Mortgage Spreads
Boyarchenko, Nina; Fuster, Andreas; Lucca, David O. - 2014
Spreads of agency mortgage-backed securities (MBS) vary significantly in the cross section and over time, but the sources of this variation are not well understood. We document that, in the cross section, MBS spreads adjusted for the prepayment option show a pronounced smile with respect to the...

Factor Glut in Asset Pricing through a Modern Optimization Lens
Bakshi, Gurdip; Christensen, Timothy; Crosby, John; … - 2023
This paper addresses questions regarding the dimensionality of the stochastic discount factor and the selection of the best factors that enter it. We analyze these questions theoretically and empirically with a novel methodology which performs both (i) estimation of factor loadings and (ii) best...

The Contribution of Frictions to Expected Returns
Hiraki, Kazuhiro - 2020
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 non-parametric theoretically founded identification strategy. The required conditions are that our estimator predicts the underlying...

The Pricing Kernel Is U-shaped
Sichert, Tobias - 2020
Numerous studies find S-shaped pricing kernels, which is conflicting with standard theory. In contrast to that, based on a novel GARCH model with structural breaks, I show that the pricing kernel is consistently U-shaped. The results are robust to variations in the methodology and hold for...

"Up" and "Down" Levy Jumps and Market Risk Premia Implications from S&P500 Options
Carverhill, Andrew P. - 2020
We model the S&P500 index options dynamics using the CGMY distribution, with independent "up" and "down" return jumps, and diffusive jump intensities. Allowing the up and down parts to be separately parameterised accounts for the dynamic smirk effect, without correlation between returns and...

Tax Risk and Asset Prices : Evidence from Dual-class Corporate Bonds in the Early 19th Century
Fleckenstein, Matthias - 2019
This paper exploits a natural experiment from the late 1800s in which many U.S. firms had inadvertently issued both taxable and tax-exempt bonds. Investors paid income tax on taxable bonds, but firms covered income tax on investors' behalf on tax-exempt bonds. Using a unique data-set of these...
