Introduction to Ramco Industries Limited
Ramco Industries Ltd. is an Indian company specializing in building materials, primarily fiber cement sheets, cement boards, and insulation products. Established in 1965, it provides durable construction solutions for residential, commercial, and industrial projects. The company is known for its commitment to quality and innovation in the construction industry.
Objective
The objective of this study is to determine the beta value of Ramco Industries Limited relative to the Nifty 50 index. Beta measures the stock’s volatility compared to the market. This analysis will help investors assess the risk associated with Ramco’s stock and make informed investment decisions.
Literature Review
1. Fama & French (1992) argue that the traditional Capital Asset Pricing Model (CAPM), which relies solely on beta to measure risk, fails to fully explain stock returns. They introduce additional factors like size and value, suggesting that beta alone is insufficient for capturing stock risk and return dynamics.
2. Black, Jensen, & Scholes (1972) find that while beta is significant in explaining stock returns, its predictive power is limited. Their study shows that other factors, beyond market risk captured by beta, affect stock pricing, challenging the idea that beta is the sole determinant of risk.
Data Collection
Data for Ramco Industries Limited and Nifty 50 was downloaded for the period from 1st January 2024 to 31st December 2024. The data was manipulated to calculate the Friday closing prices for both indices. The Nifty 50 was represented as X and Ramco Industries Limited as Y. A linear regression analysis was performed where Y was regressed on X.
Data Analysis
The regression analysis examines the relationship between Ramco Industries Limited’s stock price (Y) and the Nifty 50 index (X). Here’s what the result I get from the data:
1. Strength of the Relationship
R-Square (0.1318 or 13.18%)
→ Only 13.18% of Ramco’s stock movement is explained by Nifty 50. This means other factors also influence the stock price.
Multiple R (0.3631 or 36.31%)
→ This shows a weak positive relationship between Nifty and Ramco’s stock price.
2. Statistical Significance
P-Value for X Variable 1 (0.0131 or 1.31%)
→ Since 0.0131 < 0.05, the relationship is statistically significant, meaning Nifty 50 does have an impact on Ramco’s stock price.
3. Impact of Nifty on Ramco
Intercept (0.0026)
→ If Nifty = 0 (hypothetically), Ramco’s stock would start around 0.0026, but this has no real-world meaning.
X Variable 1 (1.0854)
→ For every 1% increase in Nifty, Ramco’s stock increases by 1.0854% on average.
→ Since Beta > 1, Ramco’s stock is more volatile than Nifty 50.
4. Confidence Interval (95%)
The real impact of Nifty on Ramco’s stock is likely between 0.2391 and 1.9317.
This range confirms that Nifty has a positive effect but with some uncertainty.
The three main point which I get from this after interpretation:-
Ramco’s stock is positively related to Nifty 50 and is more volatile.
The relationship is statistically significant but weak (low R²).
Investors should not rely only on Nifty movements to predict Ramco’s stock, as other factors also influence it.
Conclusion:
Since the Beta (1.08536) is more than 1, it indicates that Ramco Industries Limited is preferrable for short-term investment.
