Chapter 7 Bond & Stock Valuation

2
Learning Objectives Describe the key inputs and basic model used in the valuation process. Apply the basic bond valuation model to bonds and describe the impact of required return and time to maturity on bond values. Explain yield to maturity (YTM), its calculation, and the procedure used to value bonds that pay interest semiannually.

3
Learning Objectives Understand the concept of market efficiency and basic common stock valuation under each of three cases: zero growth, constant growth, and variable growth. Discuss the use of book value, liquidation value, and price/earnings (PE) multiples to estimate common stock values. Understand the relationships among financial decisions, return, risk, and the firm’s value.

**Valuation Fundamentals**

The (market) value of any investment asset is simply the present value of expected cash flows. The interest rate that these cash flows are discounted at is called the asset’s required return. The required return is a function of the expected rate of inflation and the perceived risk of the asset. Higher perceived risk results in a higher required return and lower asset market values.

5
**Basic Valuation Model V0 = CF1 + CF2 + … + CFn**

(1 + k) (1 + k) (1 + k)n Where: V0 = value of the asset at time zero CFt = cash flow expected at the end of year t k = appropriate required return (discount rate) n = relevant time period

6
**(note that a bond = debt)**

What is a Bond? A bond is a long-term debt instrument that pays the bondholder a specified amount of periodic interest over a specified period of time. (note that a bond = debt)

7
**General Features of Debt Instruments**

The bond’s principal is the amount borrowed by the company and the amount owed to the bond holder on the maturity date. The bond’s maturity date is the time at which a bond becomes due and the principal must be repaid. The bond’s coupon rate is the specified interest rate (or $ amount) that must be periodically paid. The bond’s current yield is the annual interest (income) divided by the current price of the security.

8
**General Features of Debt Instruments**

The bond’s yield to maturity is the yield (expressed as a compound rate of return) earned on a bond from the time it is acquired until the maturity date of the bond. A yield curve graphically shows the relationship between the time to maturity and yields for debt in a given risk class.

9
**Bonds with Maturity Dates**

Annual Compounding B0 = I I … (In + Pn) (1+i) (1+i) (1+i)n For example, find the price of a 10% coupon bond with three years to maturity if market interest rates are currently 10%. B0 = (100+1,000) (1+.10) (1+i) (1+.10)3

10
**Bonds with Maturity Dates**

Annual Compounding Using Excel For example, find the price of a 10% coupon bond with three years to maturity if market interest rates are currently 10%. Note: the equation for calculating price is =PV(rate,nper,pmt,fv)

11
**Bonds with Maturity Dates**

Annual Compounding Using Excel For example, find the price of a 10% coupon bond with three years to maturity if market interest rates are currently 10%. When the coupon rate matches the discount rate, the bond always sells for its par value.

12
**Bonds with Maturity Dates**

Annual Compounding Using Excel What would happen to the bond’s price if interest rates increased from 10% to 15%? When the interest rate goes up, the bond price will always go down.

13
**Bonds with Maturity Dates**

Annual Compounding Using Excel What would happen to the bond’s price it had a 15 year maturity rather than a 3 year maturity? And the longer the maturity, the greater the price decline.

14
**Bonds with Maturity Dates**

Annual Compounding Using Excel What would happen to the original 3 year bond’s price if interest rates dropped from 10% to 5%? When interest rates go down, bond prices will always go up.

Graphically Bond prices go down As interest rates go up

17
**Semi-Annual Compounding**

Bonds with Maturity Dates Semi-Annual Compounding Using Excel If we had the same bond, but with semi-annual coupon payments, we would have to divide the 10% coupon rate by two, divided the discount rate by two, and multiply n by two. For the original example, divide the 10% coupon by 2, divide the 15% discount rate by 2, and multiply 3 years by 2.

18
**Semi-Annual Compounding slightly larger than the**

Bonds with Maturity Dates Semi-Annual Compounding Using Excel If we had the same bond, but with semi-annual coupon payments, we would have to divide the 10% coupon rate by two, divided the discount rate by two, and multiply n by two. Thus, the value is slightly larger than the price of the annual coupon bond (1,136.16) because the investor receives payments sooner.

19
**Coupon Effects on Price Volatility**

The amount of bond price volatility depends on three basic factors: length of time to maturity risk amount of coupon interest paid by the bond First, we already have seen that the longer the term to maturity, the greater is a bond’s volatility Second, the riskier a bond, the more variable the required return will be, resulting in greater price volatility.

20
**Coupon Effects on Price Volatility**

The amount of bond price volatility depends on three basic factors: length of time to maturity risk amount of coupon interest paid by the bond Finally, the amount of coupon interest also impacts a bond’s price volatility. Specifically, the lower the coupon, the greater will be the bond’s volatility, because it will be longer before the investor receives a significant portion of the cash flow from his or her investment.

22
**Price Converges on Par at Maturity**

It is also important to note that a bond’s price will approach par value as it approaches the maturity date, regardless of the interest rate and regardless of the coupon rate.

23
**Price Converges on Par at Maturity**

It is also important to note that a bond’s price will approach par value as it approaches the maturity date, regardless of the interest rate and regardless of the coupon rate.

24
Yields The Current Yield measures the annual return to an investor based on the current price. Current = Annual Coupon Interest Yield Current Market Price For example, a 10% coupon bond which is currently selling at $1,150 would have a current yield of: Current = $ = % Yield $1,150

25
Yields The yield to maturity measures the compound annual return to an investor and considers all bond cash flows. It is essentially the bond’s IRR based on the current price. PV = I I … (In + Pn) (1+i) (1+i) (1+i)n Notice that this is the same equation we saw earlier when we solved for price. The only difference then is that we are solving for a different unknown. In this case, we know the market price but are solving for return.

26
Yields The yield to maturity measures the compound annual return to an investor and considers all bond cash flows. It is essentially the bond’s IRR based on the current price. Using Excel For Example, suppose we wished to determine the YTM on the following bond.

27
Yields The yield to maturity measures the compound annual return to an investor and considers all bond cash flows. It is essentially the bond’s IRR based on the current price. Using Excel To compute the yield on this bond we simply listed all of the bond cash flows in a column and computed the IRR =IRR(d10:d20)

28
Yields The yield to maturity measures the compound annual return to an investor and considers all bond cash flows. It is essentially the bond’s IRR based on the current price. Note that the yield to maturity will only be equal if the bond is selling for its face value ($1,000). And that rate will be the same as the bond’s coupon rate. For premium bonds, the current yield > YTM. For discount bonds, the current yield < YTM.

29
**Yields The yield to call is the yield earned on a callable bond.**

To calculate the yield to call, simply substitute the call date for the maturity date plus the call premium if there is one. For Example, suppose we wished to determine the yield to call (YTC) on the following bond where the call premium is equal to one year extra coupon interest.

33
**The Reinvestment Rate Assumption**

It is important to note that the computation of the YTM implicitly assumes that interest rates are reinvested at the YTM. In other words, if the bond pays a $100 coupon and the YTM is 8%, the calculation assumes that all of the $100 coupons are invested at that rate. If market interest rates fall, however, the investor may be forced to reinvest at something less than 8%, resulting a a realized YTM which is less than promised. Of course, if rates rise, coupons may be reinvested at a higher rate resulting in a higher realized YTM.

34
**Common Stock Valuation**

Stock Returns are derived from both dividends and capital gains, where the capital gain results from the appreciation of the stock’s market price.due to the growth in the firm’s earnings. Mathematically, the expected return may be expressed as follows: E(r) = D/P + g For example, if the firm’s $1 dividend on a $25 stock is expected to grow at 7%, the expected return is: E(r) = 1/ = 11%

**Stock Valuation Models**

The Zero Growth Model The zero dividend growth model assumes that the stock will pay the same dividend each year, year after year. For assistance and illustration purposes, I have developed a spreadsheet tutorial on Excel. A non-functional excerpt from the spreadsheet appears on the following slide.

**Other Approaches to Stock Valuation**

Book Value Book value per share is the amount per share that would be received if all the firm’s assets were sold for their exact book value and if the proceeds remaining after paying all liabilities were divided among common stockholders. This method lacks sophistication and its reliance on historical balance sheet data ignores the firm’s earnings potential and lacks any true relationship to the firm’s value in the marketplace.

48
**Other Approaches to Stock Valuation**

Liquidation Value Liquidation value per share is the actual amount per share of common stock to be received if al of the firm’s assets were sold for their market values, liabilities were paid, and any remaining funds were divided among common stockholders. This measure is more realistic than book value because it is based on current market values of the firm’s assets. However, it still fails to consider the earning power of those assets.

49
**Other Approaches to Stock Valuation**

Valuation Using P/E Ratios Some stocks pay no dividends. Using P/E ratios are one way to evaluate a stock under these circumstances. The model may be written as: P = (m)(EPS) where m = the estimated P/E multiple. For example, if the estimated P/E is 15, and a stock’s earnings are $5.00/share, the estimated value of the stock would be P = 15*5 = $75/share.

50
**Other Approaches to Stock Valuation**

Weaknesses of Using P/E Ratios Determining the appropriate P/E ratio. Possible Solution: use the industry average P/E ratio Determining the appropriate definition of earnings. Possible Solution: adjust EPS for extraordinary items Determining estimated future earnings forecasting future earnings is extremely difficult

51
**Decision Making and Common Stock Value**

Valuation equations measure the stock value at a point in time based on expected return and risk. Any decisions of the financial manager that affect these variables can cause the value of the firm to change as shown in Figure 8.3 below.
