Investor behavior, driven by greed and fear, fuels market volatility. Rational investing demands control over these emotions through value investing and behavioral finance, rather than following market noise or crowd sentiment. Drawing from three decades of Indian capital market trends, the book highlights how biases distort investment choices, erode returns, and trigger bubbles or crises. As an antidote, it advocates long-term, contrarian strategies, spotting risks and opportunities in stocks, PSUs, IPOs, and sectors. Practical and timely, it equips investors, brokers, fund managers, and finance students with tools to avoid hysteria, build confidence, and make safe, profitable investment decisions.
