Foundations of Finance 1 Flashcards
to move a CF foward in time
we compound it to account for anticipated growth
future value formula
FV0 = C0(1+r)^n
to move a CF backward in time
we discount it to account for the fact we have to wait for it
present value formula
PV0 = Cn / (1+r)^n
if discount rate > 0
0 < DF < 1
if discount rate < 0
DF > 1
total present value formula
C0 + C1/(1+r) + C2/(1+r)^2 + C3/(1+r)^3
NPV formula
= PV(inflows) - PV(outflows)
if NPV > 0
accept project
perpetuity
stream of equal cash flows that occur at regular intervals and last forever
perpetuity formula
PV = C/r
growing perpetuity
stream of cash flows that occur at regular intervals which grows at a constant rate forever
growing perpetuity formula
PV = C / r-g
constant annuity
stream of N equal cash flows paid at regular intervals, number of payments is fixed, start at t=1
constant annuity PV and FV formulas
PV = C/r x [1 - 1/(1+r)^N],
FV = C/r x [(1+r)^N - 1]
growing annuity
fixed number of N growing cash flows paid at regular intervals
growing annuity formula
PV = (C / r-g) x [1 - (1+g / 1+r)^N]
things to include in any NPV/IRR calculation
any CFs that arise directly from project, any cash outflows in future directly from project, any forgone income which might otherwise have been earned, any future purchases which will be reduced as result of project, effect of project on existing projects
things to exclude from any NPV/IRR calculation
any sunk or fixed costs that are independent of investment decision and cannot be recovered
cannibalisation
new investment project decreases sales of existing business
IRR
discount rate for which NPV = 0
IRR decision rule
if IRR > r accept project
cases where NPV and IRR disagree
delayed investments, non existent IRR, multiple IRRs
payback period
only accept a project if its CFs repay initial investment within a pre specified period
problems with payback period
ignores cost of capital, ignores time value of money, ignores CFs after payback period, relies on ad-hoc decision criterion
multiple IRRs
there are as many IRRs as sign changes in CF stream
mutually exclusive projects
investing in one project necessarily excudes the toher
3 differences in projects that IRR ignores but NPV doesnt
differences in scale, differences in timing, differences in risk
incremental cash flows
a CF that takes place in one project but doesn’t happen at the same time in another project
incremental IRR
IRR of differences between projects. When discount rate = IRR one project stops being optimal and the other starts
problems with incremental IRR
difficult to interpret, don’t know which project is optimal when; doesn’t say if NPV > 0; doesn’t adjust projects for different amounts of risk
calculating NPV steps
1 - find unlevered income (before interest), 2 - use to find tax payable, 3 - convert accounting profits into annual CFs by making changes for non-cash items, 4 - discount CFs to present value, 5 - sum to find NPV
non-cash items
items in a profit and loss statement that relate to accounting entries instead of actual CFs - depreciation and amortisation, capital expenditure
capital expenditures
paid immediately while they’re subtracted from earnings over the lifetime of the project through depreciation
Net Working Capital
NWC = Cash + Inventory + Receivables - Payables
Free Cash Flow
FCF = (Revenues - Costs - Depreciation)(1 - Corporate Tax Rate) + Depreciation - Capital Expenditure - (Change in NWC)
NPV: Break-even analysis
how bad would one input have to go to make NPV = 0
NPV: sensitivity analysis
calculate how much NPV varies due to change in an input parameter, holding all others constant
NPV: scenario analysis
calculate effect of simultaneously changing more than one input parameter on NPV
Profitability Index formula
PI = PV of future cash flows / initial investment
Profitability index decision rule
PV > 1, accept
Annual percentage interest rate
doesn’t take into account effects of compound interest
effective annual percentage interest rate
reflects actual returns of investing
EAR formula
EAR = (1 + APR/k)^k - 1, where interest is paid k times a year
If r is the EAR in annualised terms…
equivalent n-month rate = (1+r)^(n/12) - 1
bond
debt instrument which is marketed in the form of securities of a fixed denomination
bond buyers
investors who want stable, predictable, low risk investments; pension funds; risk averse private investors
life cycle of a bond
1) bond issued by issuer: have a prospectus which defines t&c of bond. 2) initial bondholders buy bonds and give cash. 3) if its a coupon bonds, issuer pays interest payments called coupons to bondholder, if its a zero coupon bonds, no payment. 4) End of life of bond: issuer repays face value (specified at start), face value usually = denomination. If bond is a coupon bond, final coupon payment made at same time
fixed coupons
specified at outset
floating coupons
tied to variable rate
denomination relates to
traded units of bonds
face value relates to
cash flows
tenor
remaining length of life of bonds
coupon formula
[Coupon Rate x Face Value] / N.o. of coupon payments a year
default
when issuer fails to make coupon payments or face value payment on time
collateral
issuer’s assets which prospectus states can be seized by bondholders in event of default
unsecured bond
bond with no collateral
yield to maturity
overall profit of bond considering current price and future CFs - helps ot compare to other investments
2 ways to define YTM
1) discount rate at which: PV of all future cash flows = bond current price, 2) IRR of bond given current price
Bonds: if current price > face value
bond trading at premium - pay more now than receive later
Bonds: if current price = face value
bond trading at par - pay same now as receive later
Bonds: if current price <. face value
bond trading at a discount - pay less now than receive later, YTM > Coupon Rate
Bonds risks
default (but collateral is insurance), interest rates affect bond prices
shares risk
future dividends and company cost of equity are uncertain
Bonds vs. shares
bonds have lower risk and lower return than shares
Zero coupon bonds usually
trade at a discount
PV of zero coupon bonds
PV = Cn / (1+r)^n
YTM of zero coupon bonds
YTM = (FV/P)^(1/n) - 1
usually, a higher bond tenor =
higher yield to maturity
zero coupon yield curve
plots YTM against time to maturity - specifies discount rates for risk free CFs and acts as a potential indicator for future economic activity
bond prices and interest rate/YTM move
in opposite directions
zero coupon bonds issues by governments in developed markets…
yield a risk free rate of return as government cannot in theory default on domestic currency debt obligations
coupon bonds
pay face value at maturity and regular coupon payments
current market price is
sum of present value of all future CFs
Coupon Bond: PV(constant annuity)
= C/YTM [1 - (1/(1+YTM)^N)]
Coupon Bond: PV(face value at N)
= FV / (1+YTM)^N
price of coupon bonds in words
= PV(constant annuity) +PV(face value at N)
price of coupon bond formula
P = Coupon/YTM [1 - (1/(1+YTM)^N)] + [FV / (1+YTM)^N]
if we have semi annual coupon payments
need to express YTM is semi annual rate and ensure N is in 6 month periods
expectations
have major effects on investors willingness to lend or borrow for long term
steep yield curve indicates
short term interest rates expected to rise in future
inverted/decreasing yield curve indicates
expected decline in interest rates
nominal interest rate
not adjusted for inflation
real interest rate
adjusted for inflation
if inflation > 0
nominal rate > real rate
real interest rate equation
r_r = (1+r)/(1+i) - 1
fisher equation
(r-i)/(1+i) = r - i
3 main things that affect bond prices
changes in market interest rates (creates changes in YTM), time, bond paying a coupon
as interest rate/bond yields rise
bond prices fall
as interest rate/bond yields fall
bond prices rise
high coupon bonds vs. low coupon bonds
high coupon rates are less sensitive to YTM/IR changes. CFs of high coupon bonds arrive earlier so if YTM increases, the PV of CFs in near future decline a little but CFs in distant future decline a lot
short term bonds vs. long term bonds
bonds with shorter maturity rates less sensitive to YTM/IR changes
Maturity: a bond trading at discount
will increase in price as approach maturity
maturity: a bond trading at par
will stay the same price as approach maturity
maturity: a bond trading at premium
will decrease in price as approach maturity
dirty price
includes accrued interest rate for next coupon
clean price
adjusts for effect of receiving next coupon
to receive coupon, bondholder must buy bond before
ex-coupon date. on that date, bond price falls by coupon payment amount
the presence of default risk leads to…
increased required YTM
credit ratings
debtholders rely on Credit Rating Agencys to evaluate creditworthiness of issuers.
low bond rating =
higher risk and thus higher YTM
gordon growth model def
dividends grow at a constant rate forver
gordon growth model formula
P0 = Div1/(rE - g) or = [Div0 x (1+g)] / (rE - g)
r_E
equity cost of capital - discount rate used to discount future dividends - reflects riskiness of dividends - the return we expect for holding firm equity
rE formula
r_E = (Div1/P0) + g
dividend payout ratio
fraction of earning paid out as dividends
Dividend worded formula
= (Earnings / Shares Outstanding) x Dividend Payout Ratio
dividends can be increased by
increasing earnings or payout ratio
new investments formula
earnings x retention rate
change in earnings
New investments x return on new investments
earnings growth rate
change in earnings / earnings, OR, retention rate x return on new investments, OR (1 - dividend payout ratio) x return on new investments
retention rate
1 - dividend payout ratio
Simple dividend discount model: 1-year horizon. Price and rE formula
P0 = (Div1 + P1) / (1 + rE), rE = [(Div1 + P1) / P0] - 1 = Div1/P0 + (P1 - P0)/P0
Simple dividend discount model: n-year horizon. Price formula
P0 = Div1/(1+rE) + Div2/(1+rE)^2 + … + (Divn + Pn)/(1+rE)^n
two stage dividend discount model: First Stage
first stage until time t=N we predict each dividend individually by modelling company’s performance in detail -> High Growth Stage
two stage dividend discount model: Second Stage
from time t=N assume constant dividend growth which is usually low. Use gordon growth model to value share price at t=N -> Low/Terminal Growth Stage
two stage dividend discount model: Price formula
P0 = Div1/(1+rE) + Div2/(1+rE)^2 + … + DivN/(1+rE)^N + [1/(1+rE)^N] x [(1+g)DivN/(rE-g)]
total payout valuation model- words
firms can repurchase their shares rather than/in addition to paying out dividends.
total payout valuation model: Price Formula
P0 = PV(Future total dividends and repurchases) / Current shares outstanding
Enterprise Value, EV
present value of whole company
market value of equity
= price per share x number of shares = EV - debt value + cash
EV formula
market value of equity + debt value - cash
value of firms net debt
total debt - cash
Free Cash Flow
= EBIT(1 - Corporate Tax Rate) + Depreciation - Capital Expenditure - Change in NWC
FCF Waterfall
firm generate FCF; some FCF used on debt repayments; remaining FCF belongs to shareholders; some paid out in dividends; any leftover FCF reinvested in firm
when calculating PV of FCF we discount it with
Weighted average cost of capital (WACC)
discounted FCF model method
calculate EV of firm (PV of all future FCF); calculate equity value; divide market value of equity by number of shares to get predicted current share price
discounted FCF model: EV formula
= FCF1/(1+rWACC) + FCF2/(1+ rWACC)^2 + … + FCFN/(1+rWACC)^N + [1/(1+rWACC)^N x (1+g)FCFN/(rWACC - g)]
discounted FCF model: Price formula (EV)
EV0 + Cash - Debt / Shares Outstanding
price earnings ratio
used to compare firms: P/E ratio = share price / earnings per share
other multiples to compute firm value
enterprise value multiple (EV/EBIT(DA)); sales multiples (EV/Sales); price-to-book value of equity (P/BV)
EBITDA
earnings before interest, tax, depreciations, amortisation
EBIT
earnings before interest, tax
limitations of using valuation multiples
no clear guidance on how to adjust for differences across firms; provides info about firm relative to another but no info about overall mispricing
ESG Investing: environmental
climate change, environmental sustainability
ESG Investing: social
diversity and inclusion; human rights
ESG Investing: governance
corporate structure (Chair and CEO different?); executive and employee compensation structure
challenges to divestment strategy
difficulty and controversy in identifying firms; underperformance because divestment restricts investment universe, excluding potential high performenrs
comparison conducted based on key ESG factors
environment; community and society; employees and supply chain; customer; government and ethics
methods for applying ESG criteria
exclusion screen (excluding sin stocks); including only top ESG (in each industry); combination of methods - ratings often based on old info so asset managers do own research
dirty industry example
oil
clean industry example
pharmaceuticals
advantages of ESG investing
helps reduce cost of capital and thus cost of equity; reduces downside and overall risk so lower stock volatility
disadvantages of ESG investing
restricts investment universe and efficient frontier so may reduce maximum sharpe ratio - not able to access asset pricing factors that yield as much profit
ESG investings: financial motivation
lower risk - particulalry from regulatory uncertainties
ESG investings: non-financial motivation
ethical and environmental values; impact
green bonds
debt securities issued for specific projects designed to achieve environmental goals. issuer can be firms, banks, governments
green bonds features
usually have same credit rating as conventional bonds; YTM is lower - Green Premium - cheaper way for firm to borrow money. forego some returns and accept lower yields to pursue non-financial objectives
green vs. brown stocks
interest rate of green is lower - Carbon Risk Premium - firms face higher climate and regulatory risks so investors are compensated with higher expected return
green vs. brown portfolios
green portfolios outperform brown in realised returns over long term
return
increase in the value of an investment expressed in a percentage
probability distribution
assigns a probability that each possible return will orccur
return equation with prices
(Pt+1 - Pt)/Pt
expected (mean) returns
calculated as a weighted average of the possible returns where weights correspond to possibilities
Expected return formula
E[R] = ∑_RxP_R ×R
variance
expected squared deviation from the mean - measure of how spread out the distribution is
variance formula
var(R) = E[(R - E[R])^2] = ∑_RxP_R ×(R - E[R])^2
standard deviation
square root of the variance - the volatility of a return
variance and standard deviation do not differentiate between
upside and downside risk
realized return
return that actually occurred over a particular time period
realized return formula
Rt+1 = (Divt+1 + Pt+1)/(Pt) - 1 = Divt+1/Pt + (Divt+1 - Pt)/Pt
annual total realized return
1 + Rannual = (1+RQ1) (1+RQ2)(1+RQ3)(1+RQ4)
how can we estimates the underlying proability distribution
by counting the number of times a realized return falls within a particular range
empirical distribution is obtained when
the probability distribution is plotted against historical data
average annual return
R (bar) =1/T (R1+R2+⋯+ RT) = 1/T ∑R_t
variance of realized returns
Var(R) = 1/T-1∑(Rt - R(bar))^2
two problems with looking at historical data and realized return
we dont know what investors expected in the past, the average return is just an estimate of the expected return so we need to take into account an estimation error
standard error
statistical measure of the degree of estimation error
SD(Average of Independent, Identical Risks) =
SD(Individual Risk) / sqrt(Number of Observations)
the higher the standard deviation
the higher the standard error
the lower the number of observations
the higher the standard error
excess return (or equity risk premium)
difference between the average return for an investmenet and the average return for T-Bills (government bonds)
common risk
risk that is perfectly correlated and affects all securities
independent risk
risk that is uncorrelated and affects a particular security
diversification
the averaging out of independent risks in a large portfolio
firm specific news
good or bad news about and invidivual company
market wide news
news that affects all stocks, such as news about the economy
systematic risk
will affect all firms and not be diversified
risk premium for diversifiable risk
is zero so investors are not compensated for holding firm specific risk because they can diversify to eliminated it
risk premium of a security is determined by
systematic risk
how to determine how sensitive a stock is to systematic risk
look at the average chagne in return for each 1% change in the return of a portfolio that fluctuates solely due to systematic risk
efficient portfolio
portfolio that contains only systematic risk - no way to reduce volatility without lowering expected turn
a market portfolio is assumed to be
efficeint
Beta
is the sensitivity of the security’s return to the return of the overall market - the expected percentage change in the excess return of a security for a 1% change in the excess return of the market portfolio
volatility measures
total risk - systematic and unsystematic
beta is measure of
only systematic risk
market risk premium
the reward investors expect to earn for holding a portfolio with a beta of 1
risk premium formula
risk premium = beta x market risk premium
Capital Asset Pricing Model formula
E[R] = Risk Free Interest Rate + Risk Premium = rf + beta x (E[Rmkt] - rf)
portfolio weights formula
xi = Value of intestments / total value of portfolio
