Introduction
The Indian stock market plays a crucial role in capital formation and economic development. Investors rely on various analytical tools to evaluate stock performance and make informed investment decisions. Among these tools, regression analysis is widely used to study the relationship between dependent and independent variables.
Rashtriya Chemicals and Fertilizers Limited (RCF) is a Government of India enterprise operating in the fertilizer and chemical sector. Its shares are actively traded on the National Stock Exchange (NSE). Understanding the factors influencing RCF’s share price helps investors assess risk and return.
This study applies simple linear regression analysis to examine how an independent market-related variable influences the share price of RCF.
Objectives of the Study
- To analyze the relationship between RCF share price and the selected independent variable.
- To measure the strength of the relationship using regression statistics.
- To test the statistical significance of the regression model.
- To understand the usefulness of regression analysis in stock market studies.

Literature Review
Several studies have highlighted the importance of statistical tools in financial analysis:
- Previous research indicates that regression analysis helps identify the impact of market indicators on stock prices.
- Studies on public sector undertakings (PSUs) show that macroeconomic and firm-specific factors significantly affect share prices.
- Many financial researchers conclude that regression models are effective for predicting trends, though not free from market risk.
Thus, regression analysis remains a widely accepted technique in investment research.

Interpretation:
The independent variable has a positive and significant impact on the share price of RCF. A one-unit increase in the independent variable results in an approximate 0.972 unit increase in the share price.
Conclusion
The study concludes that there exists a moderate and statistically significant relationship between the selected independent variable and the share price of Rashtriya Chemicals and Fertilizers Ltd.
The regression model explains approximately 35% of the variation in the dependent variable, indicating that while the model is useful, other external factors also influence share prices. The ANOVA and coefficient results confirm the reliability of the regression model.
Thus, regression analysis proves to be an effective tool for understanding stock price behavior, though investors should also consider qualitative and macroeconomic factors.
