Introduction:
Tech Mahindra Limited is a prominent Indian multinational provider of digital transformation, consulting, and business re-engineering services. As a key part of the Mahindra Group, the company operates globally with a presence in over 90 countries, leveraging a massive workforce of over 145,000 professionals to serve more than 1,100 clients. Headquartered in Pune, it has established itself as a leader in the communications and enterprise sectors, focusing heavily on next-generation technologies such as 5G, Metaverse, and Generative AI through its “Scale at Speed” strategy. This report analyses Tech Mahindra Ltd’s stock performance and its sensitivity to the broader market index (Nifty 50).
Objective: To calculate Beta and observe its significance.
Literature review:
1: Volatility and Sectoral Resilience
(Bangur et al., 2023) this study provides a comparative analysis of the Nifty IT index and the Nifty 50 index, examining how severe market shocks impact volatility persistence. The findings demonstrate that while the broader Nifty 50 index experiences massive volatility spikes during macroeconomic crises, the IT sector exhibits distinct and occasionally more resilient variance patterns, highlighting its unique risk-return profile within the broader market.
2: Risk-Return Dynamics of IT Constituents
(IJRAR, 2025) this research evaluates five major IT firms (TCS, Infosys, Wipro, HCL, and Tech Mahindra) against the NSE benchmarks. It confirms that while Tech Mahindra offers competitive returns, its beta of 0.84 indicates a higher sensitivity to market fluctuations compared to “defensive” peers like TCS (beta 0.57), suggesting it is better suited for investors with a higher risk appetite seeking index-linked growth.
