Introduction
Morgan Stanley is a leading global financial services firm providing investment banking, wealth management, and institutional securities services.
As a publicly traded company, its stock performance is closely linked to market indices such as the Nifty 50. Understanding its Beta (β) value helps investors assess its volatility and correlation with market movements.
Objective
To determine the Beta (β) of Morgan Stanley and assess its significance in relation to Nifty 50.
Literature Review
1. Market Volatility and Beta Analysis
Misra and Mohapatra (2015) analyze the impact of market volatility on Beta values, particularly for financial institutions like Morgan Stanley.
Their study highlights that global economic trends, interest rate changes, and monetary policies significantly influence stock movements and their correlation with major indices such as Nifty 50.
2. Stock Performance in Market Fluctuations
Gali (2021) examines how financial institutions, including investment banks like Morgan Stanley, respond to economic cycles.
Using regression models and historical stock data, the study finds that investment banks exhibit unique volatility patterns, making their correlation with major indices like Nifty 50 less predictable during market fluctuations.
Data Collection
Data for Morgan Stanley and Nifty 50 was collected from NSE for the period 31-03-2024 to 20-03-2025.
Weekly closing prices (Friday) were used to calculate returns. Morgan Stanley’s weekly returns were regressed against Nifty 50’s returns to determine Beta.
Data Analysis
Regression Equation
The regression equation describes the relationship between Morgan Stanley’s returns (Y) and Nifty 50 returns (X):
Y = -0.0097 + (0.1145 * X)
Here,
– Y represents Morgan Stanley’s weekly return.
– Xrepresents Nifty 50’s weekly return.
– The intercept (-0.0097) suggests a slight negative return when Nifty 50’s return is zero.
– The coefficient (0.1145) indicates that for every 1% change in Nifty 50’s return, Morgan Stanley’s return changes by 0.1145%, meaning it has a weak correlation with the market.

Interpretation
The regression equation describes the relationship between Nifty 50 (X) and Morgan Stanley’s stock returns (Y), indicating that Morgan Stanley’s stock return is the dependent variable, while Nifty 50 is the independent variable.
This analysis indicates that Morgan Stanley’s stock movements are largely independent of Nifty 50 trendsand do not closely follow broader market movements.
Conclusion
The Beta (β) value of 0.1145 indicates that Morgan Stanley has a very weak correlation with Nifty 50.
Its stock movements are largely independent of the overall market trends. The high p-value (0.804) suggests that the relationship between Morgan Stanley and Nifty 50 is not statistically significant.
