Introduction
Vodafone Idea Limited is a major telecommunications provider in India, formed after the merger of Vodafone India and Idea Cellular. The company delivers mobile voice and data services across 2G, 3G, and 4G networks to millions of customers nationwide. It aims to provide affordable connectivity, improved network coverage, and digital solutions to support everyday communication needs. Vodafone Idea continues to play an important role in strengthening India’s digital and telecom infrastructure.
Objective: Calculation of Beta of Vodafone Idea and observe its significance.
Literature Review
The existing literature on Vodafone Idea Limited largely focuses on the impact of the merger between Vodafone India and Idea Cellular and its implications for market competitiveness and operational efficiency. Studies highlight that the merger was strategically aimed at achieving economies of scale, optimizing spectrum usage, and strengthening market position in response to rising competition in the Indian telecom sector. Researchers note that while the merger created one of the largest telecom operators in India by subscriber base, the expected synergies were challenged by intense price wars, declining average revenue per user (ARPU), and rapid technological shifts toward data-centric services.
Another stream of literature examines Vodafone Idea’s financial and strategic challenges, particularly its high debt burden, regulatory liabilities such as AGR dues, and the need for continuous network investment. Industry analyses emphasize that these factors have constrained capital expenditure and affected the company’s ability to compete effectively with stronger rivals.
At the same time, recent studies point to Vi’s efforts in network modernization, customer retention, and selective technology upgrades as crucial steps toward long-term sustainability. Overall, the literature suggests that Vodafone Idea’s future performance depends on regulatory support, financial restructuring, and its ability to balance cost efficiency with service quality improvement.
Data Collection: The data of Nifty 50 and the data for Vodafone idea was downloaded from 01-12-2024 to 30-01-2025 form NSE India.com. This data is used for finding out the Friday closing prices for Nifty 50 and Vodafone idea. Weekly return was calculated by the formula (Yt+1-Yt)/Yt*100 and then weekly returns of the Nifty 50 was taken as X and the equity of Vodafone Idea was taken as Y. Y was regressed on X.
Data Analysis
Vodafone Idea Returns = 0.3799 − 0.0801 (NIFTY 50 Returns)
N = 48 | R² = 0.00044 | F = 0.0204 | P-value = 0.8869
- The above regression equation explains the relationship between the weekly returns of Vodafone Idea Limited (dependent variable) and NIFTY 50 weekly returns (independent variable).
- The coefficient of the NIFTY 50 returns is negative (-0.0801), indicating a weak negative relationship between market movements and Vodafone Idea’s weekly returns. This suggests that a 1-unit increase in NIFTY 50 weekly returns leads to an approximate 0.08-unit decrease in Vodafone Idea’s weekly returns, implying that the stock does not move in line with overall market trends and behaves defensively or independently.
- The t-statistic for Beta (β) is -0.143 with a p-value of 0.8869. Since the p-value is significantly greater than both 1% and 5% levels of significance, the beta coefficient is not statistically significant, indicating that market returns do not have a meaningful influence on Vodafone Idea’s returns.
- The R-square value of 0.00044 indicates that only 0.04% of the variation in Vodafone Idea’s weekly returns is explained by movements in the NIFTY 50, while nearly all variation is due to firm-specific or external factors. The F-statistic of 0.0204 with a significance value of 0.8869 shows that the overall regression model is statistically insignificant, confirming a very weak relationship between Vodafone Idea returns and market returns.
Conclusion:
β = –0.08
Since β is less than 1 and negative, Vodafone Idea’s stock shows very low sensitivity to market movements (NIFTY 50), indicating low systematic risk but high firm-specific risk. The stock does not move in line with the market and is largely influenced by company-specific factors rather than overall market trends. This makes Vodafone Idea unsuitable for market-driven or aggressive trading strategies, and it may be considered only by high-risk investors who are willing to take exposure based on turnaround potential rather than market performance.
