We present efficient partial differential equation (PDE) methods for continuous time mean-variance portfolio allocation problems when the underlying risky asset follows a jump-diffusion. The standard formulation of mean-variance optimal portfolio allocation problems, where the total wealth is...

We provide evidence that speculative capital of hedge funds is a key determinant for the profitability of optimal carry and momentum strategies in futures markets across asset classes. We construct optimal carry and momentum portfolios from the perspective of a utility maximizing risk averse...

We reveal pitfalls in the hedging of insurance contracts with a minimum return guarantee on the underlying investment, e.g.\ an external mutual fund. We analyze basis risk entailed by hedging the guarantee with a dynamic portfolio of proxy assets for the funds. We also take account of liquidity...

The study indicates that Brownian motion, finite and infinite activity jumps are present in the ultra-high frequency VIX data. The total quadratic variation can be split into a continuous component of 29% and a jump component of 71%. Jump activities on ultra-high frequency VIX data are found...

We investigate the relationship between ex-ante total skewness and holding returns on individual equity options. Recent theoretical developments predict a negative relationship between total skewness and average returns, in contrast to the traditional view that only coskewness should be priced....

A time homogeneous, purely discontinuous, parsimonous Markov martingale model is proposed for the risk neutral dynamics of equity forward prices. Transition probabilities are in the variance gamma class with spot dependent parameters. Markov chain approximations give access to option prices. The...

The effect of self-default on the valuation of liabilities and derivatives (DVA) has been widely discussed but the effect on assets has not received similar attention. Any asset whose value depends on the status, or existence, of the firm will have a DVA. We extend Burgard&Kjaer (2011) to...

Traditionally derivatives and other assets have been valued in isolation. The balance sheet of which a derivative position is part, was not included in the valuation. Recently, aspects of the valuation have been revised to incorporate certain elements of the balance sheet in the valuation....

We study minute-by-minute behavior of the VIX index and trading activity in the underlying S&P 500 options to understand the impact of macro and microeconomic forces on risk neutral volatility. VIX often increases with macroeconomic news, reflects the credibility of Fed monetary stimulus, and...

The sovereign debt crisis challenged investors in European government bonds to deal with volatile interest rate spreads. For managing sovereign risk, “Eurex” introduced futures contracts on Italian government bonds reflecting risks of lower rated countries. We analyze hedging strategies for...
