Financial & Capital Markets Flashcards
Time Value of Money
the difference in money today and at a future time
Net Present Value
PV(Benefits)-PV(Costs)
Risk Free Interest rate (rf)
The interest rate at which money can be borrowed or lent without risk over that period
Interest rate factor
(1+rf) - the exchange rate across time
Discount factor
1/1+r
Positive NPV
means it is probably best to take up the project
NPV Decision rule
When making an investment decision, take the alternative with the highest NPV.Choosing this alternative is equivalent to receiving its NPV today.
If it down to a choice between projects we should always aim to chose the project with the highest NPV
Arbitrage
The practice of buying and selling equivalent a goods in different markets of take advantage of a price difference
Arbitrage opportunity
making a profit without taking any risk or making any investment
normal market
A competitive market where no arbitrage opportunities exist.
Law of One Price
If equivalent investment opportunities trade in different competitive markets, then they must trade for the same price in both markets.
financial security (security)
An investment opportunity that trades in a financial market
A bond
A security sold by governments and corporations to raise money from investors today with the promise of payment in the future.
No arbitrage price of a security
=PV(All cash flows paid by the security)
Return
Percentage gain you earn from investing in a bond.
Gain at the end of the year/Initial Cost
Portfolio
Combination of securities
Risk Aversion
preference to safe investments rather than those that carry risk
risk premium
is the difference between the expected return on an investment - the risk free interest rate of the investment
Compounding
The process of moving a value of money from one point in time to another.
Compound interest
“Earning interest on interest”.
Discounting
Finding the equivalent value today of a future cash flow
Perpetuity
Stream of Cash Flows that occur at regular intervals and last forever.
in arrreas
When the first payment of a perpetuity occurs at the end of the first period.
Present Value of a Perpetuity
C/r
Annuity
Stream of N cash flows paid at regular intervals
Present Value of an annuity
PV(annuity of C for N periods with interest rate r=
C/r(1-1/(1+r)^N)
Future Value of an Annuity
PV x (1+r)^N
C x 1/r((1+r)^N - 1)
Growing Perpetuity
Stream of cash flows that occur at regular intervals and grow at a constant rate forever.
Present Value of a growing perpetuity
= C/r-g where r is the interest rate and g is the amount we withdraw each year.
Internal Rate of Return
The interest rate that sets the NPV of cash flows to zero
Growing annuity
a cash flow that grows at a constant rate g. The cash flow stops after a finite number of years
Present value of a growing annuity
PV = c/r-g * (1 - (1+g)^N/(1+r)^N)
Effective Annual Rate (EAR)
The total amount of interest that will be earned at the end of the year. It considers the effect of compounding
Annual Percentage Rate (APR)
Simple interest without the effect of compounding. It is typically less than the EAR. It cannot be used as a discount rate and thus must be converted to an EAR
APR —> EAR formula
1+EAR = (1+APR/k)^k where k is the compounding periods
The fisher effect
Is the relation between the nominal interest rate, real interest rate and inflation. Given by 1+real = 1+nominal/1+inflation
An increase in interest rates will typically reduce the NPV of an investment
Term structure
The relationship between the investment term and the interest rate
Can be used to compute the present and future values of risk free investments over different investment horizons
A steep yield curve indicates…
that interest rates are expected to rise. It is common on short interest rates and inflation is low or an economy is emerging from a recession
An inverted yield curve indicates….
the interest rates are expected to decline in the future
A flat yield curve indicates…
occurs when interest rates are transitioning
A humped yield curve…
occurs when rates are transitioning or market participants are attracted to a particular maturity segment of the market
What risk do treasury securities hold?
None. They are risk free
After tax interest interest rate
the amount of interest an investor can keep once the earnings have been taxed.
r~ = r * (1- t) where t is the tax rate
Opportunity cost of capital
The best available expected return offered in the market on an investment of comparable risk and term to the cash flow being discounted
What choice should be made when rules of investment conflict?
Follow the NPV
Internal rate of return investment rule?
Take any investment where the IRR exceeds the cost of capital and turn down an investment where it does not exceed the cost of capital
When will the IRR work?
for standalone projects when all negative cash flows precede the positive cash flows
What situations would the IRR conflict with the NPV
Delayed investments.
Non-existent IRR
Multiple IRR
What could the reason be for IRR not working for delayed investment?
The IRR may appear to be greater than the cost of capital however when the NPV is calculated the NPV could be negative indicating the investment should not be undertaken
What could be the issue with a non-existent IRR?
Here it would see there is no clear cut way of deciding on the project using the IRR rule but in this situation it could be that the NPV will always be positive (or negative)
What could be the issue with multiple IRRS?
Wouldn’t know when IRR to make and there is also bound and so it can make the decision difficult. To rectify this rely on the NPV
What is the advantage of the IRR?
It can measure the average return of the investment and the sensitivity of the NPV to any estimation error in the cost of capital
The Payback Rule
If the payback period is less than a prespecified time you accept the project .
Payback period
is the amount of time it take to recover or payback the initial investment
Disadvantages to the payback rule method
Ignores projects cost of capital and time value of money
Ignores cash flows after the payback period
Relies on ad hoc decision criterion about the cut off period
Project chosen based on this may not have a positive NPV
Advantages to the payback rule method
Easy to understand and apply
focuses on the liquidity of an investment project
commonly used when the capital investment is small and the horizon is short
The discounted payback period
Involves considering the time value of money by taking the discount rate into consideration. However, by the time you have calculated this you might as well work out the NPV
When using the IRR rule what must we take into consideration in order to avoid mistakes?
Projects differ in:
Scale of investment
timing of cash flows
riskiness
What effect does the scale have when comparing projects?
If a size doubles the NPV will double. However, the IRR does not
What effect does the timings of cash flow have when comparing projects?
The IRR can change as a result of differences in timings and so can change the rankings of the IRR. The NPV isnt affected
What effect does the risk have when comparing projects?
An IRR that is safe for a safe project need not be attractive for a riskier project
Incremental IRR rule
Apply the IRR rule to the difference between the cash flows of the mutually exclusive alternatives. It tells us the discount rate at which it becomes profitable to switch from one project to another
Shortcomings of the IRR
incremental irr may not exist
multiple irrs
The fact the the IRR exceeds the cost of capital does not mean the NPV is positive
when there are different costs of capital for projects it is not obvious which one to use.
Profitability index
The value created in terms of NPV for the amount of resource consumed. Starting with the highest ranking and move down the ranking until all the resource is consumed
NPV/resource consumed
Shortcomings of the profitability index
the set of projects taken following the profitability index ranking exhausts all available resources
with multiple resource constraints the index could break down completely
Bond certificate
states the terms of the bond
maturity date
the final repayment date
term
the time remaining until repayment date
Coupon
promised interest payments
Fave value
notional amount used to compute the interest payments
coupon rate
amount of each coupon payment (express as apr)
Coupon payment
CPN = coupon rate*facevalue/ no. of coupon payments per year
Yield to maturity
discount rate that sets the present value of the promised bond equal to the market price of the bond
Zero-coupon bond
a bond which does not make coupon payments
Always sells at a discount
Yield to maturity of a Zero-Coupon bond
P= facevalue/(1+YTM)^n
Law of one price guarantees what?
That the risk free interest rate equals the yield to maturity on a zero-coupon bond
Risk free interest rate with maturity n equals…
rn=YTMn
Zero coupon yield curve
a plot of the risk free zero coupon bonds as a function of the bonds maturity date
Coupon bonds
regular coupon interest payments and pays face value at maturity
Yield to maturity of a zero-coupon bond
P = CPN *1/y(1-1/1+y)^N) + facevalue/(1+y)^N
A bond is selling at a discount when…
its price is less than its face value and coupon rate is greater than YTM
A bond is selling at par when….
its price is equal to the face value and the coupon rate is equal to the YTM
A bond is selling at premium when…
its price is greater than the face value and the coupon rate is less than the yield to maturity
If a bond’s yield to maturity has not changed…
the IRR of an investment in the bond equals its yield to maturity even if you sell the bond early
Duration
measures the sensitivity of a bond’s price to change in the interest rate
As interest rates rise what happens to bond prices?
Bond prices fall
As interest rate fall what happens to bond prices?
Bond prices increase
Bond with high duration….
are more sensitive to changes in the interest rate
Price of a coupon bond
P=CPN/(1+ytm) +CPN/(1+ytm)^2……CPN+facevalue/(1+ytm)^N
Corporate bonds
bonds issued by corporations
credit risk
risk of default
yields of corporate bonds with high credit risk…
will be higher than they would be for identical default free bonds
Dividend discount model
potential cash flows…. Dividend + Sale of stock
Equity cost of capital…
the expected return of other investments available in the market rE
P0= Div1+P1/1+rE
Price of a stock today when using the equity cost of capital
If the actual stock price is found to be less than what is found to be true
there is a positive NPV
Solving for total return rE
Div1+P1/P0 which can be split into divided yield and capital gain rate
Dividend yield
the percentage return the investor expects to earn from the dividend paid
Capital gain rate
expresses the capital gain as a percentage return
Price of a Share for two years
P0 = Div1/1+rE + Div2+P2/(1+rE)^2
Total return of a stock
sum of dividend yield and capital gain rate
Dividend discount model
Initial price of a stock where the horizon N is arbitrary
P0 = Div1/1+rE + Div2/(1+rE)^2…+DivN/(1+rE)^N + PN/(1+rE)^N
What is the price of a stock if it is held forever?
Is equal to the present value of the expected future dividends it will pay
Constant dividend growth model
models dividends which grow at a constant rate
P0=Div1/rE-g where g is the growth rate
Total return of a growing dividend
rE=Div/p0 +g where g is capital gain
Implied return
Pn=P0(1+IR)^n
What is the dilemma faced when a company wants to increase its share price?
There has to be a trade off between paying out dividends and instigating growth. In order to facilitate growth some of the company earnings will have to go on investment rather than be paid out as dividends
Dividend payout rate
fraction of the company’s earnings which is used for paying dividends
Divt= earnings/shares outstanding * dividend payout rate
What two things can a company do with its earnings?
Payout to investors
retain it and reinvest
Change in earnings =
new investment * return on new investment
new investment =
earnings * retention rate
retention rate
the fraction of earnings that the company retains
earnings from growth
retention rate * return on new investment
If a firm keeps its retention rate constant…
then the growth rate in dividends will equal the growth rate of earnings
What does cutting the firms dividend depend on?
the rate of return on the new investment
Limitations to the dividend discount model
uncertainty with forecasting a firm’s dividend growth rate and future dividends
small changes in the assumed growth rate can affect the stock price greatly
Share repurchase
firm uses excess cash to buy back shares but….
the more cash firms use to rebuy stocks the less it has to pay dividends
EPS increases
Dividend discount model
PV0=PV(Future dividends per share)
Total payout model
Value of all the firms equity per share
PV0= PV(future total dividend + repurchases)/shares outstanding
Discount free cash flow model
determines the total value of a firm to all investors
Enterprise value V0=PV(future free cash flows of firm)
Free cash flow
cash flow available to pay both debt holders and equity holders
Enterprise value
market value of equity+debt - cash
value of owning the unlevered business
Share price
P0=V0+cash0-debt0/Shares outstanding
Present value of dividends payments can determine…
Stock price
Present value of total payments can determine…
equity value
Present value of free cash flow can determine
enterprise value
Valuation based on comparable firms
can estimate the value of a firm based on the value of comparable firms or investments with similar cash flows
Valuation multiple
ratio of the value to some measure of the firms scale
analogous to floor space pricing if confused
Price earnings ratio
Share price/Earnings per share
Trail earnings
earnings over the last 12 months
Forward earnings
expected earnings over the next 12 months
firms with high growth rates should….
have high P/E raitos
Other multiples
Multiples of sale
Price to book value of equity per share
enterprise value per subscriber
Limitations of multiples
When comparing there is no guidance about how to adjust for differences in future growth rates or risk. Only provides information of firm relative to others. Doe not tell us if the whole sector is overvalued
Discount cash flow methods can be…
more accurate than valuation multiples as they can incorporate specific information about the firms cost of capital or future cash flows
Efficient market hypothesis
Securities will be fairly priced, based on their future cash flows, given all information that is available to investors
Securities with same equivalent risk should have same expected return
Public, easily interpretable information means….
All investors can determine the effect of the information on a firms value
Private or difficult to interpret information means…
only a small number of investors may be able to profit by trading on their information (that they will have gathered from their own research). If trade opportunities are large more will devote time to finding alternative resources
The efficient market hypothesis does not hold but as traders trade then the prices will begin to change
Consequences for investors
if stocks are fairly priced, investors who buy stocks can expect future cash flows that fairly compensate them for their investment
average investor can invest with confidence
Implications for the corporate managers
Focus on NPV and future cash flows
avoid accounting illusions and focus on free cash flows
use financial transactions to support investment
Probability distribution
when an investment is risky, there are different returns in may earn and a probability associated with them
Expected return
weighted average of the possible returns
E[R] = Σp * R
Variance
expected square deviation from the mean
Var(R) = Σp * (R-E[R])^2
Standard deviaition
also known as the volatility
square root of variance
Realised returns
return that actually occurs over a particular time period
Rt+1 = (Divt+1 + Pt+1 - Pt)/ Pt
If a stock pays dividends at the end of each quarter what is the realised annual return?
1+Rannual = (1+RQ1)(1+RQ2)(1+RQ3)(1+RQ4)
Average annual Return
If Rt is the realised return of a security in year t, then for the years 1 through T the average return is….
Rbar = 1/T ΣRt
Variance estimate using realised returns
1/T-1 Σ(Rt-Rbar)^2
standard error
statistical measure of degree of estimator error
SD/root(no. of obs)
95% confidence interval
historical average return + or - 2 SE
Excess returns
Difference between the average return for an investment and the average return for t-bills
Independent risks
related to firm specific news. Diversified, unsystematic
Common risk
market wide news related risk/ Also known as undiversified or systematic
When stocks are combined in a portfolio what happens to the risk of the stock
the risks will average out and be diversified. Systematic risk will affect all firms and not be diversified. Therefore, volatility will decline until all that remains is systematic risk
The risk premium for diversifiable risk is….
Zero. investors are not compensated for holding stocks with firm-specific risk. The can eliminate this for free by diversifying their portfolio
Risk premium for a security is determined by…
the systematic risk
Why is volatility not a good way of determining a risk premium?
It includes diversifiable risk in the value. We need to determine how much of the volatility is down to systematic risk
An efficient portfolio
A portfolio that contains only systematic risk. The only way to reduce the risk of this portfolio is by decreasing the expected returns
Market portfolio
An efficient portfolio that contains all shares and securities in the market
