Literature review:
1) Sharma and Kulkarni (2024) examined the application of the Capital Asset Pricing Model (CAPM) on selected Nifty 50 companies using a Single Index Model approach. The study found that beta serves as a crucial indicator in measuring systematic risk and is instrumental in ranking stocks based on risk-return trade-offs. It also highlighted that stocks with higher beta tend to provide higher returns, validating the risk-return relationship suggested by CAPM.
2) Patel and Verma (2023) analyzed the performance of high beta stocks in comparison with the Nifty 50 index and concluded that beta significantly influences stock volatility and sensitivity to market movements. The study revealed that high beta stocks exhibit greater fluctuations than the market index, indicating that systematic risk plays a vital role in determining stock behavior during different market conditions.
