Abstract
The aim of this research is to provide a model for optimising the sectoral portfolio selection by using game theory during
a general elections phase. We select stocks from Bursa Malaysia and calculate the payoff for each stock and its coalition
sectors by averaging returns. The value of the game is at the same time the characteristic function of a multiple-player
game which will be applied to obtain the Shapley value using the cooperative game theory approach for finding the
optimal increment of the returns. We also compare the Shapley value percentages obtained for both periods of the 13th
Malaysia General Election (GE13) and 14th Malaysia General Election (GE14) to indicate the impact of GE14 on
investment. This research will lead to optimal portfolio selection before and after an election.
