1. INTRODUCTION
· Steel Authority of India Limited (SAIL) is a premier state-owned steel manufacturer and a designated Maharatna Public Sector Enterprise.
· The company manages a massive distribution network for iron and steel products, specializing in high-volume logistics and demand forecasting.
· SAIL focuses on large-scale industrial operations, utilizing its own captive mines for strategic raw material integration.
· Due to its complex supply chain and significant role in national infrastructure, it is a highly appropriate subject for operations and supply chain management research.
2. OBJECTIVE
· To calculate β of SAIL and observe its significance.
3. DATA COLLECTION
· Historical data of SAIL and NIFTY50 index data (downloaded from NSE website for the period 01-Dec-24 to 30-Nov-2025).
· The data was manipulated to get Friday closing prices.
4. LITERATURE REVIEW
· Research highlights SAIL’s status as a core sector leader focusing on modernization and value-added steel products to remain competitive.
5. DATA ANALYSIS
· Regression Equation: –
y = 0.060792236x + 1.394271302
where: –
y = Weekly Return for Redington Ltd.
x = Weekly Return for NIFTY
This equation tells us that if weekly returns of NIFTY increases, then weekly return for Redington Ltd also increases.
· Number of Observations = 48
· t-stat for β = 0.124929812
· p-value = 2.79465 × 10⁻⁶ èThis indicates that since p-value < 0.05, β is statistically significant at 1% level.
· R2 = 0.382597262 è This indicates that around 15% of the weekly return for Redington Ltd. is explained by the weekly return for NIFTY. 85% is the error due to the other variables which are not in model.
· F = 28.50566241 è The overall model is statistically significant.
6. CONCLUSION
Here β = 0.060792236 è Since β ≥ 1, it is good for short-term investment if NIFTY rises.
