Statistical arbitrage with mean-reverting overnight price gaps on high-frequency data of the S&P 500
Stübinger, Johannes; Schneider, Lucas - In: Journal of risk and financial management : JRFM 12 (2019) 2/51, pp. 1-19
This paper develops a fully-fledged statistical arbitrage strategy based on a mean-reverting jump-diffusion model and applies it to high-frequency data of the S&P 500 constituents from January 1998-December 2015. In particular, the established stock selection and trading framework identifies...

Optimal control strategies for the premium policy of an insurance firm with jump diffusion assets and stochastic interest rate
Guerdouh, Dalila; Khelfallah, Nabil; Vives, Josep - In: Journal of risk and financial management : JRFM 15 (2022) 3, pp. 1-19
In this paper, we present a stochastic optimal control model to optimize an insurance firm problem in the case where its cash-balance process is assumed to be described by a stochastic differential equation driven by Teugels martingales. Noticing that the insurance firm is able to control its...

Default risk and cross section of returns
Cakici, Nusret; Chatterjee, Sris; Chen, Ren-Raw - In: Journal of risk and financial management : JRFM 12 (2019) 2/95, pp. 1-15
Prior research uses the basic one-period European call-option pricing model to compute default measures for individual firms and concludes that both the size and book-to-market effects are related to default risk. For example, small firms earn higher return than big firms only if they have...

Bond risk premia and restrictions on risk prices
Hevia, Constantino; Sola, Martin - In: Journal of risk and financial management : JRFM 11 (2018) 4, pp. 1-22
Researchers who estimate affine term structure models often impose overidentifying restrictions (restrictions on parameters beyond those necessary for identification) for a variety of reasons. While some of those restrictions seem to have minor effects on the extracted factors and some measures...

The equity curve and its relation to future stock returns
Stotz, Olaf - In: Journal of risk and financial management : JRFM 13 (2020) 2/19, pp. 1-16
Using option prices, a new method for estimating the term structure of expected stock returns (equity curve) is proposed. We analyse how the equity curve relates to future stock returns and obtain three main results. First, a higher level of the equity curve is associated with higher future...
