Data Analysis
Rail Vikas Nigam Limited (RVNL) Returns = 455.67 − 0.0091 (Market Index)
The above regression equation explains the relationship between the dependent variable (RVNL stock returns) and the independent variable (market index) using 48 observations.
• The coefficient of X Variable 1 is negative (−0.0091), indicating a negative relationship between the market index and RVNL stock returns. This implies that a one-unit increase in the market index leads to an average decrease of approximately 0.009 units in RVNL returns, suggesting an inverse movement between the stock and the broader market during the observed period.
• The t-statistic is −5.73 with a p-value of 7.25E−07, which is significantly below the 1% and 5% levels of significance. This confirms that the coefficient is statistically significant, indicating that changes in the market index have a meaningful impact on RVNL’s stock returns.
• The R-square value of 0.4168 indicates that approximately 41.68% of the variation in RVNL stock returns is explained by movements in the market index, reflecting a moderate explanatory power of the regression model.

Conclusion
• The regression analysis indicates a moderate and statistically significant negative relationship between RVNL stock returns and the market index. The estimated beta coefficient (β = −0.0091) is negative and statistically significant (p-value = 7.25E−07), suggesting that RVNL’s returns tend to move oppositely to broader market movements during the study period.
• With an R² value of 0.4168, a substantial portion of the variation in RVNL returns is explained by market movements, indicating meaningful market linkage, though firm-specific factors also play an important role. The significant F-statistic confirms the robustness of the regression model. Overall, RVNL exhibits a statistically significant but inverse sensitivity to market trends, highlighting the importance of both macroeconomic conditions and company-specific dynamics in determining its stock performance.
