| Abstract: | Investment portfolio insurances have been widely used in investment industry worldwide since the invention of option theory. Constant proportional portfolio insurance (CPPI) strategies are the first choices of the portfolio managers of large size safe type funds because of the simplicity of the models, the flexibility to include risk profiles of the investors and the easiness to implement. In this paper we generalize the simple CPPI strategies to more general classes and find the relationship between CPPI and options. We also discuss the effects on CPPI strategies of no borrow constraints. We test the application of CPPI strategies in Chinese stock markets. |
