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 …

A small but ambitious literature uses affine arbitrage-free models to estimate jointly U.S. Treasury term premiums and …

An Asset Pricing Theory of Volatility Tail Behavior
Bakshi, Gurdip - 2012
We contrast two different asset pricing models, where the pricing kernel either (i) increases in the volatility dimension, reflecting investors' aversion to volatility, or (ii) could be non-monotonic in volatility, reflecting heterogeneity in investors' beliefs. The two models yield opposite...

Understanding Short and Long-Run Risk Premia
Buraschi, Andrea - 2013
This paper studies the predictability of S&P500 returns using short term risk premia as a conditioning variable. We construct dividend prices using futures data and identify short term risk premia by projecting excess returns of dividend claims on their lagged prices. Regression results 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...

Time-Varying Risk Premiums and Term Premiums in Commodity Futures
Chaves, Denis B. - 2017
Term premiums, defined as the excess return of long-dated contracts over short-dated contracts, in commodity futures are strongly predictable, both in the time series and in the cross section, by roll yield spreads. Strategies that exploit this predictability show sizable Sharpe ratios and are...

Yields versus Expected Returns of Corporate Bonds : Some Unexpected Results
Beliaeva, Natalia - 2019
We derive expected bond return equations for various structural credit valuation models with alternative stochastic processes and boundary conditions for default given in Merton [1974], Merton [1976], Black and Cox [1976], Heston [1993], Longstaff and Schwartz [1995], and Collin-Dufresne and...

Beta Risk in the Cross-Section of Equities
Boloor, Ali - 2019
We develop a continuous-time intertemporal CAPM model that allows for risky beta exposure, which we explicitly specify. In the model, the expected return on a stock depends on beta's co-movement with market variance and more generally with the stochastic discount factor and deviates from the...

Disagreement Beta
Gao, George - 2018
When two investors agree to disagree on market prospects and bet against each other, both expect to profit from their trades. Hence, an increase in disagreement leads to higher perceived trading profits and lower marginal utilities for both investors, so disagreement betas can affect...

The Pricing of Market Jumps in the Cross-Section of Stocks and Options
Babaoglu, Kadir - 2018
Market index and individual stock returns exhibit jumps in addition to normal shocks. Equities have exposure to the market and sensitivity to the market is important for explaining equity returns and option prices. I develop a new factor model that explores (i) if a separate beta for market...
