1. Relationship of Nifty 50 with JSW Steel
The Indian stock market index Nifty 50 represents the overall performance of the top 50 large-cap companies listed on the National Stock Exchange (NSE). JSW Steel, being one of India’s leading steel manufacturers, is influenced by broader market movements, economic conditions, infrastructure demand, and investor sentiment.
This study examines the relationship between Nifty 50 (independent variable) and JSW Steel share returns/prices (dependent variable) using simple linear regression analysis. The objective is to understand whether movements in the Nifty 50 significantly explain changes in JSW Steel’s stock performance.
The regression equation derived from the analysis is:
JSW Steel = 0.1821 − 0.5181 (Nifty 50)
This equation indicates a negative relationship, meaning that an increase in Nifty 50 is associated with a decrease in JSW Steel returns during the study period. However, statistical testing is required to evaluate the reliability of this relationship.

- Since Significance F (0.1504) > 0.05, the regression model is not statistically significant.
- This implies that Nifty 50 does not significantly explain changes in JSW Steel share price during the study period.
Coefficient Analysis
Intercept
- Coefficient: 0.1821
- P-value: 0.7839
The intercept is statistically insignificant, indicating no meaningful base value when Nifty 50 is zero.
Nifty 50 (Independent Variable)
- Coefficient: -0.5181
- t-statistic: -1.4624
- P-value: 0.1504
Although the coefficient suggests a negative impact of Nifty 50 on JSW Steel, the p-value indicates that this relationship is not statistically significant. The confidence interval includes zero, confirming uncertainty in the relationship.
6. Conclusion
The regression analysis reveals that the relationship between Nifty 50 and JSW Steel share price is weak and statistically insignificant during the study period. The model explains only a small portion of price variation, indicating that JSW Steel’s stock performance is influenced more by company-specific factors such as steel demand, raw material prices, global commodity cycles, and government infrastructure policies rather than overall market movements alone.
Therefore, investors should not rely solely on Nifty 50 movements to predict JSW Steel’s share price behavior. Future studies may include additional variables such as steel prices, GDP growth, interest rates, and global market indices for better explanatory power.
