This study titled “A Comparative Performance Appraisal of Fundamental Analytical Vs. Technical Analytical Strategies of Investment in the National Stock Exchange” examines and compares two major approaches used in stock market investment decisions. Fundamental Analysis evaluates a company’s intrinsic value through financial statements, earnings, assets, liabilities, and economic factors, whereas Technical Analysis focuses on price movements, trading volume, and chart patterns to predict future market trends. The study is based on both primary and secondary data. Primary data was collected from 100 respondents using a structured questionnaire to analyse investor awareness, preferences, and behaviour towards both analytical approaches. Secondary data was gathered from company reports, journals, stock market publications, and online financial sources. Statistical tools such as Chi-square, ANOVA, and Correlation analysis were used to examine relationships and differences among the variables influencing investment decisions. The findings reveal that both Fundamental and Technical Analysis significantly contribute to investment decision-making, though their effectiveness varies depending on market conditions and investor preferences. The study concludes that neither method can be considered universally superior; instead, a combination of both approaches provides a more comprehensive understanding of market behaviour and supports better investment decisions. The research recommends that investors adopt a balanced strategy integrating financial fundamentals with market trend analysis to maximize returns and minimize investment risks.
