| Abstract: | This paper analyzes not only the relationship of portfolio insurance strategy and option,but also that of portfolio insurance strategy and convex payoff function based on option pricing theory.By setting up portfolio insurance model we draw the conclusions of the characteristics of portfolio insurance investors under different conditions: 1) investors′ risk tolerance increases with wealth more rapidly than that of the average investor;2) investors′ expectations are more optimistic than average,would benefit from portfolio insurance. |
