Risk management of interest rate derivative portfolios : a stochastic control approach
Kiriakopoulos, Konstantinos; Koulis, Alexandros - In: Journal of risk and financial management : JRFM 7 (2014) 4, pp. 130-149
In this paper we formulate the Risk Management Control problem in the interest rate area as a constrained stochastic portfolio optimization problem. The utility that we use can be any continuous function and based on the viscosity theory, the unique solution of the problem is guaranteed. The...

Univariate and multivariate GARCH models applied to Bitcoin futures option pricing
Venter, Pierre J.; Maré, E. - In: Journal of risk and financial management : JRFM 14 (2021) 6, pp. 1-14
In this paper, the Heston-Nandi futures option pricing model is applied to Bitcoin futures options. The model prices are compared to market prices to give an indication of the pricing performance. In addition, a multivariate Bitcoin futures option pricing methodology based on a multivatiate...

Hedging long-dated oil futures and options using short-dated securities : revisiting Metallgesellschaft
Doran, James S.; Ronn, Ehud I. - In: Journal of risk and financial management : JRFM 14 (2021) 8, pp. 1-10
Since the collapse of the Metallgesellschaft AG due to hedging losses in 1993, energy practitioners have been concerned with the ability to hedge long-dated linear and non-linear oil liabilities with short-dated futures and options. This paper identifies a model-free non-parametric approach to...

Pricing perpetual American put options with asset-dependent discounting
Al-Hadad, Jonas; Palmowski, Zbigniew - In: Journal of risk and financial management : JRFM 14 (2021) 3, pp. 1-19
The main objective of this paper is to present an algorithm of pricing perpetual American put options with asset-dependent discounting. The value function of such an instrument can be described as VωAPut(s)=supτ∈TEs[e−∫0τω(Sw)dw(K−Sτ)+], where T is a family of stopping times, ω is...

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...
