CFA Level 1 - Part 5 Equity and Fixed Income

Markets
Market execution mechanisms
1) quote driven markets
    customers trade with dealers
2) order driven markets
   use rules to match buyers to sellers
3) brokered markets

Equity Indexing
Index weighting
1) Price weighting
               Pi
  wi = ----------
         Σi=1nPi
2) Equal weighting
            1
  wi = -----
            N

3) Market capitalization weighting
               QiPi
  wi = -------------
         Σi=1nQiPi

Need of rebalancing for equal weighting
                                                          total shareholder's equity
book value of equity per share = ----------------------------------
                                                         total  shares outstanding


Need to understand the below:
price return of price weighting
price return of equal weighting
total return of equal weighting
price return of market cap. weighting
total return of market cap. weighting


                                                         365
Day Sales Outstanding (DSO) = --------------------
                                                    credit sales/AR

                                                         365
Day Inventory on Hand (DOH) = -----------------
                                                     COGS/Avg Inv

                                                              365
Day payable Outstanding (DPO) = -------------------
                                                          purchase/AP


Operating cycle = DSO + DOH
Cash conversion cycle:  DSO + DOH - DPO

Receivable turnover = credit sales / AR
Inventory turnover = cogs / avg inventory
Receivable turnover = purchases / avg payable

cogs = beginning inv + purchase - ending inv

Equity valuation
Present value model
  dividend discount model
                        Dt
  Vi = Σt=1-----------
                       (1+r)t

                        Dt            Pn
  Vi = Σt=1n----------- + --------
                       (1+r)t       (1+r)n

  gordon growth
                   D1
      Vi =   ---------
                  r - g
     g = b * roe
     b: ( 1 - dividend payout ratio)
     g: growth rate
     roe : return on equity

  multi stage dividend growth model

  FCFE model
                          FCFEt
  Vi = Σt=1-------------
                             (1+r)t

Multiplier model
  P/E = p/ (r - g)  p: dividend payout ratio
  P/B
  P/CF
  enterprise value multiple
     EV = debt + preferred stock + common stock - cash
     EV/EBITDA

Asset based model
  estimate the fair value of the companies asset and liabilities
  useful for companies that do not have high level of intangibles or off the book assets

  assets + liabilities
  -------------------------  = asset based value
   shares outsanding

Margin Call:
based on equity in the position
short sell margin call:

 maintenance margin = (Price + initial margin value - current value) / current value

long position margin call:

 maintenance margin = (current value - Price + initial margin value) / current value

Bonds:
tenor: term to maturity
current yield : annual coupon / bond price
yield to maturity : internal rate of return
   higher the ytm, lower the bond price

bond indenture: the bond legal contract
debentures: a type of bond, can be secured or unsecured

Callable bonds
  american call: call at any time on the first cal date
  european call: only once
  bermuda call: call on specified dates

Putable bonds:
  a put provision has value to bondholders

Commercial paper:
  issue $50,000, 180 day USCP, 5%
  interest : 50,000 * 0.05 * 180/360

Contingency provisions:
   clauses in indenture: call provision, put provision, conversion provision

Bond price <--------> market discount rate
                     inverse

Bond price <---------> coupon
                 low coupon, more price volatile
                 given changes in ytm

Bond price <----------> maturity
               longer term bonds, more price volatile

Bond price, market discount rate is CONVEX relationship

Price and yields:
  PVfull = PVflat + AI ,  PVfull : dirty price, PVflat : clean price

  AI = t/T * PMT  , t/T : fraction of the coupon period that has gone by

  PVfull = PV*(1 + r)t/T

Matric pricing
  use interpolation to find the bond price , from other bond price of tenor and coupon

Z-spread
  yield spread over government spot curve, zero volatility spread
                PMT                   PMT+FV
  PV =  ------------- + --- + ------------
            (1+z1+Z) 1             (1+zn+Z)N

 z1 .. zn : benchmark spot rates

Duration: bond price sensitivity to ytm or yield curve
Macaulay Duration
Modified Duration = MacDur / (1+r)
                                    PV- - PV+
Approx ModDur = ----------------------
                                 2(ΔYield)(PV0)

%ΔPVfull = -AnnualModDur * ΔYield

coupon rate ↑ --> MacDur ↓

time to maturity↑ --> MauDur↑

ytm ↑ --> MacDur ↓


                                       PV- - PV+
Effective Duration = ----------------------
                                    2(ΔCurve)(PV0)

Money Dur = AnnualModDur * PVfull

ΔPVfull = -MoneyDur * ΔYield

PVBP = estimate of change in full price given a 1bp change in ytm
                                      PV- - PV+
                   PVBP = ----------------------
                                           2

                                     PV- - PV- 2*PV0 
Approx Convexity   = ----------------------
                                      (Yield)2*(PV0)

ΔPVfull = -MoneyDur * ΔYield + 1/2 * MoneyConv * (ΔYield)2

%ΔPVfull = -AnnualModDur * ΔYield + 1/2 * AnnualModConv * (ΔYield)2


Bonds with embedded option (or floating rate bond) uses effective duration to measure interest rate risk -> effective duration allows for changes in bond's cash flow

Macaulay Dur inversely related to coupon rate, ytm

Macaulay Dur positively related to time to maturity

Convexity is a positive attribute for a bond

more convex --> price ↑ more when interest rate ↓

return impact = -(ModDur * Δspread) 1/2 * ModConv * (Δspread)2

credit migration risk: risk that a bond issuer's creditworthiness may lower

market liquidity risk: risk that the price of investor transact is different from price of market
