Abstract

The study aimed to construct an optimal portfolio using Sharpe’s Single-Index Model under the constraint of no short selling. To achieve this, daily stock data from companies listed on the Abu Dhabi General Market Index (ADI) were analyzed using Excel for the period from January 1, 2021, to August 31, 2023. The findings indicated that investors can select securities for their optimal portfolio by applying the simple gradient method with specific financial ratios in the Abu Dhabi Securities Market. Additionally, the study revealed that, according to this model, investors can choose well-performing securities and exclude those with lower performance. The optimal portfolio constructed using Sharpe’s model provides the best risk-return trade-off compared to the reference portfolio or the Abu Dhabi market portfolio. The study recommended that investors adopt the Sharpe Single-Index Model and leverage its results to construct optimal portfolios efficiently, saving time, effort, and cost. Moreover, it suggested conducting further research to explore the application of Sharpe’s model in building optimal portfolios in other Arab markets, to benefit from its findings.
