The study looked at how investors can choose stocks to invest in by analyzing the financial health of companies. Healthy companies grow, make profits, have little debt, and lots of cash. Analysts use fundamental analysis to find the true value of a company's stock. If a stock is worth more than its market price, it's undervalued; if it's worth less, it's overvalued. Investors who focus on long-term growth prefer companies with strong fundamentals over short-term price changes. The study used ratios like DPS, EPS, and debt-equity ratio to compare intrinsic value with market value of shares. TCS, Bajaj Auto, and Yes Bank were analyzed in the study.
