Financial markets are complex systems influenced by various factors including interest rates, market expectations, and macroeconomic indicators. Understanding how bonds and stocks are valued, as well as the concept of duration and its relationship with market yields, is crucial for investors, financial analysts, and policymakers. This paper addresses several key problems related to bond pricing, stock valuation, and interest rate sensitivity, providing a detailed exploration grounded in financial theory and empirical evidence.

Bond Valuation and Market Price Determination

The first problem involves calculating the current market price of Western Enterprises’ bonds, which have 10 years remaining maturity, a $1,000 face value, an annual coupon rate of 9%, and a yield to maturity (YTM) of 7%. The bond’s price can be deduced by discounted cash flow analysis, where the present value of future coupon payments plus the present value of the face value is computed using the YTM as the discount rate. Mathematically, the bond price (P) is given by:

P = \sum_{t=1}^{n} \frac{C}{(1 + YTM)^t} + \frac{FV}{(1 + YTM)^n}

Where C is the annual coupon payment ($90), FV is the face value ($1,000), n is the number of years (10), and YTM is 7%. Such calculations indicate that when a bond's coupon rate exceeds the YTM, its market price exceeds its face value, reflecting a premium. Using the present value of an annuity for coupons and a lump sum for the face value yields a bond price of approximately $1,083, suggesting that investors are willing to pay more for bonds offering higher coupon payments relative to prevailing interest rates (Fabozzi, 2016).

Present Value of Bonds with Semiannual Coupons

Next, the fair present value of bonds with a 10% coupon rate paid semiannually, face value of $1,000, and varying maturities (10, 15, and 20 years) is assessed at a required rate of return of 8%. The semiannual coupon payment is $50, and the number of periods doubles due to semiannual payments. The valuation involves adjusting the coupon rate and YTM to a semiannual basis. The general formula remains similar, with the key difference being the number of periods (2 per year) and the semiannual discount rate (YTM/2 = 4%). As maturity increases, the present value of bonds tends to increase, but the rate of increase diminishes over longer maturities, demonstrating the convexity property of bond prices (Mishkin & Eakins, 2018). The calculations support the observation that longer-term bonds generally have higher present values, subject to interest rate environment.

Stock Valuation: Growth and Dividend Discount Models

Two different stock valuation scenarios are provided. For Safeco Corp., with an expected growth of 10% and a recent dividend of $1.20, the Gordon Growth Model (Dividend Discount Model) applies:

P = \frac{D_1}{r - g}

Where D_1 is the next period's dividend, r is the required return (12%), and g is the growth rate (10%). Calculating D_1 = $1.20 * (1 + 0.10) = $1.32, the fair value is approximately $66, using:

P = \frac{1.32}{0.12 - 0.10} = $66

This indicates a relatively low valuation typical of high-growth stocks with typically high P/E ratios. For the second case, where dividends follow a constant growth of 1.5%, and the current dividend is $2.50, the stock's value depends on the required rate of return. Using the same formula, for r = 12%, the stock's fair value computes to about $125. At a higher required return of 15%, the valuation drops, illustrating the inverse relationship between discount rate and present value.

For the supernormal growth scenario, with dividends growing at 8% for the initial six years followed by a perpetual 3%, a two-stage dividend discount model applies. The present value of dividends during the supernormal growth phase is calculated by projecting dividends over six years and discounting them, then adding the value of the stock at the end of this period using the Gordon model with the perpetual growth rate. The calculation reveals a higher present value due to the initial accelerated growth, emphasizing the importance of growth patterns in stock valuation (Bodie, Kane, & Marcus, 2014).

Duration and Interest Rate Sensitivity

Duration measures the sensitivity of a bond's price to changes in interest rates. For a bond with a five-year maturity, a 10% semiannual coupon, and selling at par, the duration depends inversely on the YTM. When the yield is 12%, the duration is shorter than when it is 14%, indicating greater interest rate sensitivity at lower yields. Empirical formulas and calculations show that duration increases as YTM decreases, reflecting longer effective maturities (Fabozzi, 2016). Plotting duration versus YTM illustrates a declining trend, underpinning the typical inverse relationship—higher yields result in shorter durations, which reduces interest rate risk.

Bond Price Changes and Duration Approximation

The impact of market yield shifts on bond prices—both immediate and approximated by duration—demonstrates the practical utility of duration in risk management. For a $100 million portfolio of 30-year bonds, a ±0.10% yield change causes relatively minor price fluctuations, whereas a ±2.00% change induces substantial deviations. Using the duration rule, the predicted price changes closely approximate actual market price changes for small yield shifts, but diverge for larger shifts, revealing the limitations of linear approximation at higher interest rate volatilities (Mishkin & Eakins, 2018). The error is quantified by comparing duration-based estimates with actual calculations, emphasizing the importance of convexity adjustments for precise risk assessment.

Conclusion

In conclusion, understanding bond valuation, stock valuation, and duration is fundamental for effective financial decision-making. Bonds with longer maturities tend to have higher present values but are also more sensitive to interest rate changes, as reflected in duration. Stock prices are highly sensitive to growth expectations and required returns, highlighting the importance of growth forecasts in valuation models. The inverse relationship between yield to maturity and duration underscores the need for investors to consider interest rate risk in their portfolios. While duration provides a useful approximation for bond price changes, incorporating convexity enhances accuracy, especially during volatile interest rate environments. Overall, mastery of these concepts equips investors and analysts with critical tools for navigating the complexities of fixed income and equity markets.
