Objectives: To calculate beta & observe its significance.
Literature Review:
1. The beta estimation in Indian stock markets this study examines how beta is estimated in the Indian stock market and evaluates its reliability using statistical tools like regression and residual analysis. the research highlights that beta is widely used to measure market risk but may sometimes give biased results due to issues like volatility and data irregularities. (Dash, M. (2015)
2. An Empirical CAPM Exploration this research uses the Capital Asset Pricing Model (CAPM) to analyse how beta explains stock returns in the Indian market. It finds that market risk (beta) significantly influences stock returns, confirming that stocks move in relation to market indices like Nifty 50. (Farhana, K. C. P. M., & Azees, A. P. (2025).
Data Collection:
1. Data for Nifty 50 or your company was downloaded from National Stock Exchange company for the period 1st January,2025 to 31st December,2025. The data was manipulated to get Friday closing prices of Nifty Fifty and Power Finance Corporation Ltd.
2. Weekly returns were calculated. Weekly returns of nifty fifty are (X) and weekly returns of your company (Y) was regress on (X).
Data Analysis:
Y= 0.9395+1.0165x
N= 48, R2 = 0.94363 F = 770.147, t Stat = 27.75, P-value = 2.2543
The regression equation indicates the relationship between Market Return (X) and Power Finance Corporation Return (Y). The R Square value is 0.94, which means 94% of the variation in Power Finance Corporation’s return is explained by the Market Return, while the remaining 6% is due to other factors not included in the model. This shows a very strong explanatory power of the model. The F value is 770.15 with a Significance F (p-value) of 0.000, which is less than 0.05. Hence, the overall regression model is highly statistically significant at the 5% level. The p–value of the coefficient for Market Return is 2.25E-30, which is also less than 0.05. This indicates that Market Return has a statistically significant impact on Power Finance Corporation’s return. The intercept is 0.94, meaning that if the Market Return is 0, the return on Power Finance Corporation is expected to be approximately 0.94%. The coefficient (beta) of Market Return is 1.02, which implies that for every 1 unit increase in Market Return, Power Finance Corporation’s return increases by 1.02 units.
This shows that the stock return of Power Finance Corporation is slightly more volatile than the market and moves very closely in the same direction as the market (high positive correlation).
Conclusion:
The regression analysis shows that Power Finance Corporation has a strong and significant relationship with the market. With a high R² of 0.94, most of the stock’s movement is explained by market returns. The beta of 1.02 indicates that the stock moves slightly more aggressively than the market, but largely in the same direction. Overall, the model is statistically significant, confirming that market performance is a key driver of the company’s returns.
