Optimal Portfolios with Guarantee at Maturity: Computation and Comparison
نویسندگان
چکیده
Portfolio insurance allows investors to recover, at maturity, a given percentage of their initial capital. This limits downside risk in falling markets. Besides, it allows some participation in rising markets. One of the standard portfolio insurance methods is the Constant Proportion Portfolio Insurance (CPPI). We analyse options on cushion associated to CPPI. This kind of Power options corresponds in particular to the solution of a portfolio optimization problem in which an additional guarantee constraint must be satisfied at maturity. We also compare this strategy with the standard OBPI method JEL: C 61, G 11.

On the Computation of Optimal Monotone Mean-Variance Portfolios via Truncated Quadratic Utility
We report a surprising link between optimal portfolios generated by a special type of variational preferences called divergence preferences (cf. [8]) and optimal portfolios generated by classical expected utility. As a special case we connect optimization of truncated quadratic utility (cf. [2]) to the optimal monotone mean-variance portfolios (cf. [9]), thus simplifying the computation of the ...
متن کاملOutperformance Testing of a Dynamic Assets Portfolio Selection Supplemented with a Continuous Paths Levy Process
This study aims at getting a better performance for optimal stock portfolios by modeling stocks prices dynamics through a continuous paths Levy process. To this end, the share prices are simulated using a multi-dimensional geometric Brownian motion model. Then, we use the results to form the optimal portfolio by maximizing the Sharpe ratio and comparing the findings with the outputs of the conv...
متن کاملCorporate Bond Portfolios and Macroeconomic Conditions∗
We propose an approach to optimally select corporate bond portfolios based on bond-specific characteristics (maturity, credit rating, coupon, illiquidity, past performance, and issue size) and macroeconomic conditions (recessions and macroeconomic uncertainty measures). The approach relies on a parametric specification of the portfolio weights and allows us to consider a large cross-section of ...
متن کاملComparison of Portfolios Formed by Use of Grid Strategy Model Based on New and Traditional Variables Performance With Sharpe and Treynor Measures (Evidence of IRAN Exchange)
In this research, performance of portfolios formed by use of grid strategy based on new variables (aggressive, indifference and defensive stocks) presented by Rahnamaye Roodposhti (1388), and traditional ones (growth, growth-value and value stocks), calculated with Sharpe and Treynor performance measures and tested by an Active portfolio management approach to identify the portfolios by perform...
متن کاملPortfolio Selection with Options∗
I introduce dynamic option trading and non-linear views into the classical portfolio selection problem. The optimal dynamic option portfolio is characterized explicitly in terms of its expected sensitivities (Greeks) and the role of the meanvariance efficient portfolio is played by the “Greek-efficient” portfolio. This is the portfolio that has the optimal sensitivities to chosen risk factors. ...
