| Abstract: |
| In this article, we consider an optimal portfolio selection problem with power utility function under principal guaranteed. By Lagrange multiplier and portfolio replicating approach, we obtain the optimal wealth process and the optimal portfolio, which extends the results of optimal portfolio selection with constraint. |
| Key words: optimal portfolio Lagrange multiplier power utility funtion principal guaranteed |
