Portfolio Insurance: the Extreme Value of the Cppi Method
نویسنده
چکیده
This paper applies the extreme value theory to the Constant Proportion Portfolio Insurance (CPPI) . In particular, the choice of the standard multiple is detailed according to the statistical estimation of the behaviour of extreme variations in rates of assets returns. Moreover, we introduce the distributions of interarrival times of these extreme movements and show their impact on the portfolio insurance. We illustrate these results on S&P 500 data.

On Path–dependency of Constant Proportion Portfolio Insurance strategies
This paper evaluates the path–dependency/independency of the most widespread Portfolio Insurance strategies. In particular, we look into various Constant Proportion Portfolio Insurance (CPPI) structures and compare them to the classical Option Based Portfolio Insurance (OBPI) and with naive strategies such as Stop-loss Portfolio Insurance (SLPI). The paper is based upon conditional Monte Carlo ...
متن کاملConstant Proportion Portfolio Insurance in presence of Jumps in Asset Prices
Constant proportion portfolio insurance (CPPI) allows an investor to limit downside risk while retaining some upside potential by maintaining an exposure to risky assets equal to a constant multiple m > 1 of the cushion, the difference between the current portfolio value and the guaranteed amount. In diffusion models with continuous trading, this strategy has no downside risk, whereas in real m...
متن کاملOn the Stochastic Dominance of Portfolio Insurance Strategies
This paper compares the performance of the two main portfolio insurance strategies, namely the Option-Based Portfolio Insurance (OBPI) and the Constant Proportion Portfolio Insurance (CPPI). For this purpose, we use the stochastic dominance approach. We provide several explicit sufficient conditions to get stochastic dominance results. When taking account of specific constraints, we use the con...
متن کاملPortfolio Insurance: determination of a dynamic CPPI multiple as function of state variables
This paper examines the CPPI method (Constant Proportion Portfolio Insurance) when the multiple is allowed to vary over time. A quantile approach is introduced, which can provide explicit values of the multiple as function of the past asset returns and volatility. These bounds can be statistically estimated from the behaviour of variations of rates of asset returns, using for example ARCH type ...
متن کاملOptimal Portfolios with Guarantee at Maturity: Computation and Comparison
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 corresp...
