One of the most important issues in the capital market is awareness of the level Risk of Companies, especially “systemic risk (unavoidable risk)” that could affect stock returns, and can play a significant role in decision-making. The present study examines the relationship between stock returns and systematic risk based on capital asset pricing model (CAPM) in Tehran Stock Exchange. The sample search includes panel data for 50 top companies of Tehran Stock Exchange over a five year period from 1387 to 1392. The results show that the relationship between systematic risk and stock returns are statistically significant. Moreover, the nonlinear (quadratic) function outperforms the linear one explaining the relationship between systematic risk and stock returns. It means that the assumption of linearity between systematic risk and stock returns is rejected in the Tehran Stock Exchange. So we can say that the capital asset pricing model in the sample is rejected and doesn’t exist linear relationship between systematic risk and stock returns in the sample.

Model CAPM dapat menentukan minimum required return harga suatu asset dari investasi yang berisiko pada kondisi ekuilibrium. Dalam penelitian ini pengambilan sampel dilakukan dengan teknik non random sampling pada metoda purposive random sampling dikumpulkan melalui data sekunder dengan teknik pengumpulan data cross section. Penelitian ini mengacu kepada dua variabel yaitu, required return yang merupakan tingkat pengembalian yang diharapkan akan direalisasikan dari suatu investasi, dan Systematic risk sebagai suatu ukuran risiko yang tidak dapat dihilangkan melalui diversifikasi, yang mana merupakan risiko yang masih menjadi masalah bagi investor. Hasil penelitian diperoleh bahwa, semakin besar nilai required return, semakin besar pula nilai ?i saham tersebut begitu pula sebaliknya semakin kecil nilai required return semakin kecil pula nilai ?i saham tersebut.     Kata Kunci: Capital Asset Pricing Model, Systematic Risk, Required Return   ABSTRACT In an effort to develop the capital market industry in Indonesia, the BEI continues to educate and develop the industry in a better direction, the purpose of the BEI is not merely to focus on adding new investors, but also to invest in the capital market, which will indirectly increase the amount active investor in the Indonesian capital market.

This research is an explanatory study that explains investment and portfolio analysis using the capital asset pricing model as a tool for investment decision making on individual shares with a stock research population incorporated in the IDX30 BEI index. The CAPM model can determine the minimum required return on the price of an asset from investments that are at risk under equilibrium conditions. In this study the sampling was done by non-random sampling technique in the purposive random sampling method collected through secondary data with cross section data collection techniques. This study refers to two variables namely, required return which is the expected rate of return of an investment, and Systematic risk as a measure of risk that cannot be eliminated through diversification, which is a risk that is still an issue for investors. The results showed that, the greater the value of required return, the greater the value of the stock ?i and vice versa the smaller the value of the required return the smaller the value of the stock ?i.
