Session 14

 16-02-2026

In this class, we explored the concept of beta as a measure of systematic risk and examined how it reflects the sensitivity of a stock’s returns relative to overall market movements. We applied this concept by comparing the beta of Tata Consultancy Services with the benchmark index NIFTY 50. Since the market index has a beta of 1 by definition, it serves as a reference point for evaluating whether a stock is more or less volatile than the market.

What I found particularly insightful was how beta translates theoretical risk concepts into practical investment analysis. A stock with a beta greater than 1 indicates higher sensitivity to market fluctuations, while a beta below 1 suggests relative stability. Understanding this helped me appreciate how investors align their portfolio choices with their individual risk tolerance. I now view beta not just as a statistical measure but as a strategic indicator that guides portfolio construction and risk management.

Session 13

  10-02-2026 The focus of todays session was the relationship between risk and return, particularly through the classification of systematic and unsystematic risk. We also discussed how actual returns consist of both expected and unexpected components, with the unexpected portion representing the uncertainty investors face. The concept of diversification was introduced as a method for reducing company-specific risks. From my perspective, this session clarified an important principle in financial economics: not all risks are rewarded with higher returns. Systematic risk, which affects the entire market, cannot be eliminated through diversification and therefore plays a central role in determining expected returns. In contrast, unsystematic risk can be minimized by holding a diversified portfolio. This realization shifted my perspective on investment strategy. Instead of focusing on individual stocks, I now see the importance of portfolio construction and asset allocation as key to...

Session 16

24-02-2026 The discussion on Weighted Average Cost of Capital (WACC) helped me understand how companies evaluate the true cost of financing their operations. Earlier, I saw WACC mainly as a formula, but working through the problem made me realize that it actually reflects a firm’s capital structure and overall risk profile. We were given inputs like the market value of debt and equity, cost of debt, beta, tax rate, market risk premium, and risk-free rate. Calculating the cost of equity using the CAPM formula , helped me clearly see how systematic risk (beta) influences the return expected by shareholders. Another important step was adjusting the cost of debt by multiplying it with (1 – tax rate). This highlighted the tax shield benefit, showing how interest payments reduce taxable income and lower the effective cost of borrowing. Assigning weights based on market values of debt and equity made the calculation more meaningful. It showed how each source of finance contributes proportiona...

Session 15

  23-02-2026 This session introduced the Capital Asset Pricing Model (CAPM) and its role in explaining the relationship between risk and expected return. CAPM demonstrates that the return investors demand from an investment depends on the risk-free rate, the market risk premium, and the asset’s beta. The class also covered the concept of cost of debt, which represents the effective interest rate a firm pays on borrowed capital. This discussion helped me understand how financial theory provides structured frameworks for evaluating investment opportunities and financing decisions. CAPM illustrates that investors require compensation both for the time value of money and for the systematic risk they assume. At the same time, the concept of cost of debt highlighted how firms strategically balance different sources of financing. Since interest payments are tax-deductible, debt financing can reduce the effective cost of capital, influencing a firm’s capital structure decisions. I now se...
