Dynamic option-based investment strategies are derived and discussed for investors exhibiting downside loss aversion. The problem is solved in closed form when the stock market is characterized by stochastic...
For a correct aggregation of losses resulting from different risk types and, hence, a correct computation of total economic capital requirements, existing stochastic dependencies between risk-specific...
Risk budgets are frequently used to allocate the risk of a portfolio by decomposing the total portfolio risk into the risk contribution of each component position. Many approaches to portfolio allocation...

Counterparty risk is difficult to include systematically in credit default swap pricing. Reviving Merton’s structural approach – and generalising to higher dimensions – makes it tractable. By Alex Lipton and Ioana Savescu
The value of early termination clauses in derivatives depends crucially on the type of close-out value used and on the counterparty risk, and embeds optionality in even the most vanilla swap contracts. In the case of the so-called risk-free close-out,...
Withdrawal guarantees ensure the periodic deduction of a constant dollar amount from a fund for a fixed number of periods. If the fund is depleted before the last withdrawal, the guarantor has to finance the difference. Andreas Kunz derives a robust hedging...
Traditional models for wrong-way risk focus on the correlation between default and exposure – a blunt tool for a tail risk. Alternatives are thin on the ground, but a scenario-based approach may provide some fresh insight. Laurie Carver introduces this...
Debit valuation adjustments are becoming well understood for derivatives and liabilities – but can affect the asset side of the balance sheet too. Specifically, assets such as so-called goodwill depend on the creditworthiness of the firm. Chris Kenyon...
Withdrawal guarantees ensure the periodic deduction of a constant dollar amount from a fund for a fixed number of periods. If the fund is depleted before the last withdrawal, the guarantor has to finance the difference. Andreas Kunz derives a robust hedging...
The risk of exposure and counterparty default probability both increasing – so-called wrong-way risk – is usually understood in terms of the correlation between the two variables. But this approach is focused more on the centre of the distribution,...
