Title: Relation of Indices Nifty50 with Rail Vikas Nigam Limited (RVNL)
Author: Rituparna Prakash Baliarsingh
Introduction:
Rail Vikas Nigam Limited (RVNL) was incorporated on 24 January 2003 as a wholly owned enterprise of the Ministry of Railways, Government of India, with the objective of accelerating the implementation of railway infrastructure projects. RVNL was established to mobilize extra-budgetary resources and enhance project execution capacity for India’s expanding railway network. The company plays a key role in the development of new railway lines, doubling and gauge conversion projects, electrification, metro rail, and overseas railway infrastructure. RVNL was listed on the Indian stock exchanges in April 2019, marking a significant milestone in its evolution as a major public sector infrastructure company supporting India’s rail modernization efforts.
Objective:
To determine the Beta of Rail Vikas Nigam Limited (RVNL) with respect to Nifty 50 and assess its statistical significance.
Literature Review:
Varma (2018) investigates the extent of corporate governance practices in Indian Railway Public Sector Undertakings (PSUs), finding that while formal governance norms exist, adherence—particularly regarding independent directors and board effectiveness—remains limited. The study situates corporate governance as a vital mechanism for transparency and fraud prevention, noting its increasing importance for sustained organizational performance. This research aligns with broader scholarly work that highlights the governance challenges in Indian PSUs, where state control and weak implementation often undermine the full realization of governance frameworks. Together, these studies suggest a pressing need for strengthened governance protocols and improved compliance to enhance accountability and stakeholder trust.
The working paper by Sitharamaraju et al. (2020) examines public-private partnership (PPP) frameworks in Indian Railways, highlighting how financial constraints and investment challenges have driven policy shifts toward private sector collaboration. The authors situate PPPs as pivotal to bridging infrastructure financing gaps and improving operational efficiency in large public transport systems. Their review engages with earlier policy reports and national planning documents that discuss modal cost comparisons and the need for private capital infusion to augment rail infrastructure development. Findings from this paper align with broader infrastructure research that emphasizes the complexity of PPP implementation, particularly in balancing public interests with commercial viability and risk allocation.
Data Collection:
The data for Rail Vikas Nigam Limited (RVNL) and Nifty50 were collected for the period from 01-12-2024 to 30-11-2025. The dataset was manipulated to extract Friday closing prices, where Nifty50 was treated as the independent variable (X) and Rail Vikas Nigam Limited (RVNL) as the dependent variable (Y). A regression analysis was conducted on this data.
Data Analysis:
Equation: Rail Vikas Nigam Limited (RVNL) = 1.2688 + 2.0959 Nifty50
R square = 0.35260 | F value = 24.50897 | P value = 1.08E-05
No. of observations = 48
Interpretation:
The regression equation explains the relationship between the independent variable (X) and the dependent variable (Y) for Rail Vikas Nigam Limited (RVNL). The estimated regression equation is
Y = 1.2688 + 2.0959X, where the intercept value of 1.2688 represents the expected value of the dependent variable when the independent variable is zero. The positive regression coefficient of 2.0959 indicates that a one-unit increase in the independent variable leads to an approximate 2.10 unit increase in the dependent variable, signifying a positive relationship between the variables. Based on 47 observations, the R-square value of 0.3526 suggests that approximately 35.26% of the variation in the dependent variable is explained by changes in the independent variable, while the remaining variation is attributed to other factors not included in the model. The F-statistic value of 24.5089 with a significance level of 1.08E-05 indicates that the overall regression model is statistically significant at the 5% level. Furthermore, the t-statistic value of 4.9506 for the independent variable, along with a p-value of 1.08E-05, confirms that the independent variable has a statistically significant impact on the dependent variable. Hence, the results demonstrate a meaningful linear relationship between the selected variables during the study period.
Conclusion:
Beta is greater than one it is good for short term investment if Nifty 50 rises.
