Portfolio Optimisation Using Risky Assets with Options as Derivative Insurance
We introduce options on FTSE100 index in portfolio optimisation with shares in which conditional value at risk (CVaR) is minimised. The option considered here is the one that follows FTSE100 Index Option standards. Price of options are calculated under the risk neutral valuation. The efficient portfolio composed under this addition of options shows that put option will be selected as part of th...
متن کاملThe appeal of risky assets
A fund’s performance is usually compared to the performance of an index or other funds. If a fund trails the benchmark, the fund manager is often replaced. We argue that this may lead to excessive risk-taking if fund managers differ in ability and have the opportunity to take excessive risk. To match the benchmark, fund managers may increase the risk of their portfolio even if this decreases th...
متن کاملFlexibility and the Demand for Risky Assets
To a decisionmaker facing a choice over a set of risky prospects the issue of ‘flexibility’, i.e., the ability to postpone other decisions until after the uncertainty is resolved, is a crucial one. Tisdell (1963) for example, has shown that the well known ‘preference’ of a risk neutral firm for random over constant prices (with the same mean) reduces to indifference when it is assumed that the ...
متن کاملHedging of Options in Jump-Diffusion Markets with Correlated Assets
We consider the hedging problem in a jump-diffusion market with correlated assets. For this purpose, we employ the locally risk-minimizing approach and obtain the hedging portfolio as a solution of a multidimensional system of linear equations. This system shows that in a continuous market, independence and correlation assumptions of assets lead to the same locally risk-minimizing portfolio. ...
متن کاملIterative Speedup by Utilizing Symmetric Data in Pricing Options with Two Risky Assets
The Crank–Nicolson method can be used to solve the Black–Scholes partial differential equation in one-dimension when both accuracy and stability is of concern. In multi-dimensions, however, discretizing the computational grid with a Crank–Nicolson scheme requires significantly large storage compared to the widely adopted Operator Splitting Method (OSM). We found that symmetrizing the system of ...
