Abstract


 This research seeks to analyze the development of syariah stock optimization method using Nonlinear Programming in order to provide an optimal portfolio as a reference in improving the quality of syariah capital market in Indonesia.

The data in this research is the stock price information syariah incorporated in the Jakarta Islamic Index (JII). Selected data with Reward to Variability (RVAL) were then analyzed using theories in financial mathematics and developed using quadratic programming. The result of this research is systematic step formulation to maximize profit level and minimize risk level of syariah share investment incorporated in JII in January 2015-December 2016 time domain.
