This research paper highlights the significance of the Media and Entertainment industry, which includes film, print, radio, and television. The Government of India has supported the industry’s growth through initiatives such as digitisation of cable distribution. The study also examines fluctuations in share prices of selected companies using the stock market.

The Indian Media and Entertainment (M&E) industry is a fast-growing sector of the Indian economy, driven by rising consumer demand and increasing advertising revenue. According to the FICCI–EY report, the advertising-to-GDP ratio is expected to increase from 0.38% in 2019 to 0.4% by 2025. Media markets operate through interconnected product, advertising, and audience markets, highlighting the complex structure and economic linkages within the Indian media industry.
Data Collection:
Data for the NIFTY 50 index and Sun TV Network Limited were downloaded from the website (www.nseindia.com) for the period from 1 December 2024 to 30 November 2025. Weekly closing prices were obtained using Friday closing values. Based on these prices, weekly returns for both NIFTY 50 and Sun TV were calculated. The weekly returns of NIFTY 50 were taken as the independent variable (X), while the weekly returns of Sun TV were taken as the dependent variable (Y). Subsequently, Y was regressed on X.
Data Analysis:
The equation:
Sun TV Returns = 0.835 + 0.929 × NIFTY 50 Returns,
The above regression equation explains the relationship between the dependent variable (stock returns) and the independent variable (NIFTY 50 index values) using 49 weekly observations.
1. The beta (slope) coefficient of 0.9297 indicates a positive relationship between NIFTY 50 weekly returns and the company’s weekly returns. This means that if NIFTY 50 weekly returns increase by 1 unit, the company’s weekly returns are expected to increase by approximately 0.93 units.
2. The t-statistic of 3.78 for the beta coefficient and the p-value of 0.000454, which is less than 0.01, indicate that the relationship between NIFTY 50 returns and the company’s returns is statistically significant at the 1% level.
3. The R-square value of 0.237 shows that approximately 23.7% of the variation in the company’s weekly returns is explained by movements in the NIFTY 50 index, while the remaining 76.3% variation is due to other factors not included in the model.
4. The F-statistic is 14.27, with a Significance F value of 0.000454, which is less than 0.01. This confirms that the overall regression model is statistically significant.
Conclusion:
The study concludes that the stock has a positive but moderate beta value of 0.93, indicating that it moves in the same direction as the market but with slightly lower sensitivity to NIFTY 50 movements. Since the beta is less than one, the stock is considered more suitable for long-term investment, particularly for investors who prefer relatively stable returns with lower exposure to market risk.
