How does margin work?
How do you calculate the margin requirement on a purchase?
- # of shares x Price x Margin requirement
Example 1:
- We are buying 100 TD Waterhouse @ $23.00 - 100 x $23.00 x 30% = $690.00
This is the margin requirement to buy this stock.
Remember that TD Waterhouse is option eligible and trades above $5.00
Example 2:
- We want to buy 1000 shares of Cognicase @ $19.00. COG is not option eligible. - 1000 x $19.00 x 50% = $9500
This is the margin requirement on this trade. You are borrowing the remaining $9500 from TD Waterhouse.
Example 3:
- You want to buy $25,000 face value of a Quebec Provincial Strip bond @ $95 - 25,000 x $95/100 x 10% = $2375
Again, this amount is your margin requirement. The $21,375 balance is borrowed from TD Waterhouse.
Don’t forget to make sure that the annual yield on the bond you’re buying is at least the cost of borrowing. (7% in this example)

Margin Account Rates
President account:
Canadian debit:
$0 - $99,999 - Prime + 0.75% = 7.00%
$100,000+ - Prime = 6.25%
US debit:
$0 – $24,999 - Prime + 1.00% = 9.25%
$25,000 – $99,999 - Prime + 0.75% = 9.00%
$100,000+ - Prime + 0.50% = 8.75%
What if the market goes down?
If the price of the stock you bought on margin drops, its loan value decreases.
This might result in a margin call.
A margin call is an amount of money a client has to come up with in order to keep its holding.

Below maintenance margin (Mm): Investor must do something:
1. Sell some shares or 2. Send cash 3. Value of securities no longer support loan 4. MM determines what investor must do
Above initial margin (Im): Investor May:
1. Do nothing 2. Buy additional shares with no additional cash 3. Increase loan amount 4. IM determines what investor may do

Given:
You Short 100 shares @ $50
Dividends of $1/share are paid
You cover position @ $40
Profit = $900
Given:
You short 100 shares @ $50
Dividends of $1/shares are paid
You cover position @ $60

No Margin:
Purchase 100 shares @ $50
Sell 100 shares @ $70 in 1 year:
Profit = $2,000
Return = $2,000/$5,000 = 40%
Margin:
Purchase 200 shares @ $50
(Borrow $5000 @ 9%)
Interest = $450
Sell 200 shares @ $70 in 1 year:
Profit = $3,550
Return = $3,550/$5,000 = 71%
10
No Margin:
Purchase 100 shares @ $50
Sell 100 shares @ $30 in 1 year:
Loss = $2,000
Return = ($2,000)/$5,000 = (40%)
Margin:
Purchase 200 shares @ $50
(Borrow $5000 @ 9%)
Interest = $450
Sell 200 shares @ $30 in 1 year:
Profit = $4,450
Return = ($4,450)/$5,000 = (89%)

Measure of Return & Risk
HPR (Holding period return) = Ending value of inv. Beginning value of inv.
Ex. You commit $200 for one year @ end you get 220
HPR = 220/200 = 1.10 In % term on annual basis
HPY (holding period yield) = HPR - 1 = 1.10 – 1= 10%
Annual HPR = HPR1/n (n: no. of years)
Ex. Initial Inv. $250 $350 after 2 years
HPR = 350/250 = 1.4
Annual HPR = 1.4½ =1.1832
=1.1832-1 = 18.32%
Computing mean historical returns:
1. AM (arithmetic mean) = Σ HPY/n 2. GM (geometric mean) = [(HPR1)x(HPR2)…..(HPRn)] 1/n -1
Ex:
Year Initial Value End Value HPR HPY 1 100 115 1.15 0.15 2 115 138 1.20 0.20 3 138 110.4 0.80 -0.20
GM = [1.15 x 1.20 x 0.8]1/3 -1 = 3.353%
AM = [0.15 + 0.20 + (-0.20)] = 5% 3
Compare
15
AM biased upward ex: Year Initial inv. End inv. HPR HPY 1 50 100 2 1 2 100 50 0.5 -0.5 AM= [1+ (-0.5)] = 50 = 0.25 = 25% 2 2 GM= [2 x 0.5]1/2 -1 = 11/2 -1 = 0%
If inflation in the market the portfolio
Calculating expected rates of return: An investor expects a certain rate of return for his future investment. The historical data is used as a benchmark for the possibility of future return. A 10% RR expectation could yield a range of -10% +25%
The investor assigns probability values to all possible return
E(Ri) expected return = Σ (probability of return)x(possible return)
E(Ri) =(1)(0.05) = 0.05
E(Ri) = (-0.15)(0.2)+(0.15)(-0.2)+(0.7)(0.1)=0.07

Measure the risk of expected rates of return
Investors quantify dispersion (instead of graph presentation) using statistical techniques: Variance & standard deviation to compare risk & return for alternative investments.
Variance 2) = Σ (probability) x (possible return – expected return)²
= Σ(Pi) [Ri- E(Ri)]²
Ex1: 2 =1(0.05-0.05)² = 1 x 0 = 0 No variance, no risk
Ex2: 2 = 0.15(0.2-0.07)² + 0.15(-0.20-0.07) + 0.7(0.1-0.07)² = 0.0141 The greater the dispersion the greater the risk
Standard deviation ( = √ 2 or √ Σ Pi[Ri-E(Ri)]² = 0.11874
Coefficient of variation (CV) = S.D. E(R) Used in an unadjusted 2 or Data misleading
Ex:
Inv. A Inv. B E(R) 0.07 0.12
0.05 0.07
By observation Inv. B is riskier than Inv. A using CV
CVA = 0.05 = 0.714 0.07
CVB= 0.07 = 0.583 0.12
Inv. B less riskier than Inv. A

Bonds
Fabozzi (Chapter 7 – Fabozzi text)
Debt securities (with no embedded options – callable, putable, convertible) have the following fundamental Price/Yield relationship:
Callable bonds:
1. Call option gives the holder the right to purchase @ fixed price in future 2. The right to purchase rests with issuer 3. Below yield Y’: Investors anticipate that firms (issuer) may call bond 4. Investor receive call price 5. Bond’s market price is bonded by call price 6. Reinvestment risk : investor will have to invest @ rate. Both coupon & principal 7. Negative convexity
Yield Price
Y’ Yield

Convexity Negative
Option free bond
23
Putable bonds:
1. Option gives holder the right to sell bond @ a fixed price in the future 2. Right to sell rest with investor 3. Investor has the right to sell bonds @ put strike price 4. Above Y’ investor begin to anticipate put bonds back to issuer
Duration Macaulay:
1st derivative of bond’s price function with yield (math)
To find price volatility find value of duration
1) Duration is a measure of bond’s sensitivity to change in yield i.e. Estimating interest rate risk. [Ave. Mat. Of C.F., math: weighted ave. time
2) Modified duration calculation = Y - Y+ 2 V0 (∆ Ex. 15 yrs (option-free) bond, c=7%, trading @ par I.R. 50bp, P=95.58 [n=15, put = 7, fv= 100, I/Y = 7.5, CPT PV= 95.586] I.R 50 bp, P= 104.701 M.D. = 104.7 – 95.58 2(100)(0.005) 3) Estimating price change with M.D : ex 150bp Estimate = (-1) x D x (∆ = (-1) 8.845 x (150%) = 13.2675 Actual = [n= 15, pmt = 7, fv = 100, I/Y = 7% - 1.5 % CPT PV = 115.0561 4) Effective duration calculation (option adjusted): ex. Assume bond callable @102.5 Duration = 102.5 – 95.856 2(100)(0.005) 5) Portfolio duration = Dba Pba + Dbb Pbb

Bond Pricing theorems: (Assume 1 coupon payment/year)
1) If bond price P0 , Yield & the reverse, ex:
5 yrs bond, P0 = $1000, c = $80 If P0= $1100, Y = 5.76% If P0= $900, Y = 10.68%
2) If bond yield does not change over its life, size of premium or discount towards maturity to par value, as its life gets shorter.
Ex. If P0 = $883.31, y=9%
P0, a year later = $902.81, y=9% (coupon 6%)
3) If yield stable over its life, size of premium & discount will decrease @ an increasing rate, accelerate towards maturity.
Ex. P5 (issued today) = $883.31 (different from par) = $116.69 P4 = $902.81 = $97.19
P3 = $924.06 = $75.94
4) If yield , P0 , by an amount > corresponding fall in P0, that occur if there were an equal-sized Y.
Ex: 1% yield P0 $42.12 (increase)
1% yield P0 $39.93 (decrease)
5) If coupon rate is high % change P0 owing to yield change is smaller.
Ex. Bond D, C = 9%, y=7% : P0 change = 3.889% Bond C, C = 7%, y=7% : P0 change = 3.993% Convexity:
1 & 4 theorems led to bond valuation called convexity

How to immunize: Ex: A portfolio manager is required to have one cash flow of $1,000,000 in 2 years. Bond available 1 yr & 3 yr How much should be invested in each issue? The D of portfolio of bonds = weighted average of D. of individual bonds. W1 + W3 = 1 (W1 x 1) + (W3 x 2.78) = 2 W1, W3 are proportions of funds to be invested in 1, 3 yrs. bonds W1 = 0.4382 ie 43.82% of funds W3 = 0.5618 i.e 56.18% PV of P1 = $972.73 (c = 7%) PV of P3 = $950.25 (c = 8%) PV of 1,000,000 @ 10% Y for Yr 2 = 1,000,000 = 826,446 1.102
Types of passive bond management strategies
1) Net worth immunization: Matching duration of assets, liabilities Problems: Commercial banks mismatch of maturities – short term deposits &bank loans Bank search strategy may have equal duration – different terms
2) Target date immunization: Duration = horizon date Pension plan to provide firm income for retirement to avoid I.R. change
3) Cash flow matching and dedication: A. Cash flow matching (single period) B. Dedication (multi periods)
Manager select 0 and/or coupon bond: where cash flow = obligation This strategy avoids (-) impacts of I.R. changes as goals are always met.
26
Contingent immunization calculation
Combination active and passive strategy Min. required return must be immunized, manage the surplus Given: $10 million portfolio 2-year horizon date In 2 years, portfolio value must be at least $11 million (could be 12 million) Current interest rate = 10% $11M (1.1)² Could actively manage $10M – $9.09 M = $0.91M. If lose that entire amount, immunize at that point.
If you do not lose that amount, you do not immunize & earn more than minimum require return
= $9.09 M, immunized would give minimum required return

Before starting stock analysis, investor should look
1. Macroeconomic 2. Industry analysis
Top-down analysis A. Global economy: diversification – systematic & unsystematic
Risk: A.1 info on foreign firms A.2 disclosure A.3 accounting standards A.4 political risk A.5 exchange rate risk Ex. Emerging market, mutual funds
B. Domestic Micro-economy 1. Gross domestic product (G+S production) 2. Employment: workforce (working and actively searching) 3. Inflation rate, CPI, standard living 4. Interest rates - household, business 5. Budget deficit diff. gov. spending + revenue 6. Sentiment – optimism & pessimism of consumer & producer, willingness to produce & consume Ex. If nation’s economy is auto production For domestic usage & export If car replacement longer impact GDP, employment, …. Potential emerging of new industry ex. parts

Federal Government Policy 1) Fiscal policy The federal government`s spending and tax actions (demand-side economics) 2) Monetary policy The manipulation of the money supply (demand-side economics)
A. Open market operations of the FRS (buying/selling US government bonds) Buying bonds increases the money supply Selling bonds decreases the money supply
B. Altering the discount rate. Short term rate charges to banks, rate signals expansionary policy
C. Altering the reserve requirement. Cash of bank deposits with fed 3) Supply side economics Increase productivity; decease taxes. Investment work

Interest rate
1. Supply of funds from savers. Households 2. Demand of funds from businesses to finance: Physical plant, equipment,
inventories….etc.
3. Gov. Net. Supply. Demand for funds as modified by actions of fed res bank Monetary: I.R. & MS Fiscal: Gov. spending +taxes Budget deficit: difference between gov. rev. & gov. spending. Large gov. borrowing force up I.R Crowd out private borrowing Private borrowing & inventory chocking off

The Business Cycle: is the repetitive cycle of recession & recovery
1. The peak : is the transition from the end of an expansion to the start of a contraction 2. The through: occurs “ the bottom of a recession as the economy enters a recovery 3. Cyclical industries: are sensitive to state of economy. @through before recovery
attractive investment Firms: produce consumer durable: automobile
4. Defensive industries: industries produce basic necessities of life, food producers, pharmaceuticals, public utilities. In recession they outperform cyclical firms low betas
The problem is to I.D: peaks & throughs Economy in actual recession?
5. Growth company : experience above average growth in sales & earning than economy
Y>IRR (cost of capital). Retain large % earning to invest in above average projects. Identified after results out to the public. Efficient market theory N/A, info net ave.
Undervalued/fairly valued. Search for them before IPO
6. Speculative companies: Assets involve risk Large chance to lose, small chance to gain Return: 1) low 2) nonsexist 3) negative Loto 6/49 better, penny stocks

C. Sensitivity to the business cycle
1. Sensitivity of sales: is a major determinant, if industry is cyclical or defensive.
If product is a basic necessity of life, low-cost item relatively unaffected by B.C. If product is a consumer durable, expensive item affected by B.C.
2. Operating leverage: Relationship between variable and fixed cost.
- Firms F.C. are sensitive to B.C. because costs will be incurred regardless of the level of
production & sales - Firms V.C will reduce cost with production
3. Financial leverage: Debt vs. equity financing
Debt – payment to bondholders are fixed, must be met regardless of earnings

The Graham-Rea Model (highest reward-to-risk)
1934 Benjamin Graham book security analysis Future earning as determinant of stock’s value 1974 Benjamin Graham & James Rea repudiated the above principles because of: Market is efficient (more than previous) Alternate approach: Certain stocks of certain firms may have inefficiencies to spot Examine financial statements, compare stock value to AAA bonds Rewards & risks yes & no answers Rewards Q.
1) Is P/E < ½ reciprocal AAA bond yield? Ex: if y=12%, recip = 1/0.12 = 8.3, 8.3/2=4.16, P/E,4.16
2) Is P/E<40% of its 5 yrs P/E average (P/E current year) 3) Is dividend yield > 2/3 AAA bond yield? 4) IS P0<2/3 book value per share? B.y= tot. Assets = tot. Debt/ out. Shares 5) IS P0<2/3 Net current Asset value/share? Curr. A- total debt/ out. Shares
Risk Q. 6) Is debt/equity>1? Total debt/total equity 7) Is current ratio>2? C.R = Current Assets/Current liabilities 8) Is total debt<2 net current assets?( Current assets= current-total debt) 9) Has E/S growth of last 10 yrs average min 7% per year?
E0 (earnings last year) = E-10(earnings 10 years ago)(1+g)10 E0 = E-10(1+g)10 if yes
10) In #9 more than 8 were less than -5% (steady earning) Method of selecting stocks (undervalued) to buy Remove all stock with YES answer to Q.6 Remove stocks that do not provide Yes to Q1, Q3 or Q5
To sell: If stocks 50% or 2 years passed since purchase Revisit the questions to eliminate stocks.

The quest for value
Bennett Stewart, EVA & MVA Stern Stewart Bennett idea with regards to E/share:
- Myth: accounting clever presentation / dressing up! - Cutting to R&D, avoid acquisition to avoid goodwill & amortization - Differ expenses that could lead to performance
Market needs earnings? No Value EVA: (Economic value added) Capital budgeting
- Refuse (-) projects & investment companies - Measure Value & performance - Improve management skills - Max return + R&D - Liquidate unproductive assets & capital: land, rail.. - Retire line of credit
NOPAT (Net operating profit after tax) EVA (earning = NOPAT – cost of capital (WACC) Capital: equity, debt, all sources of money (credit line) Cost Cost is minimum required by shareholders >WACC Ex. EVA, EVA = 25Mil – 26 Mil = (-1) Reject-proj.
Ex: Two companies profit 1 million each A B Capital 5 million 10million
Ex: TSE: 145 companies surveyed 65 (-) EVA MVA = MKT value – capital = PV of all future EVA MVA= EVA + EVA ….. N. (1+K)1 (1+K)2

Basic Option Terminology 1) Call: buyer has the right to purchase underlying asset 2) Put: buyer has right to sell underlying asset 3) Writer(seller) of call option: Commitment to sell underlying asset 4) Writer of put option: the commitment to buy underlying asset 5) Writing a covered call: own the underlying stock
Writing a naked call: not owning the underlying stock 6) Buyer and sell have opposite price expectations 7) Premium is the price of the contract. (intrinsic + time) 8) Options may be: exercised, traded in the open market, allowed to expire worthless.
American vs. European options 1) An American option contract allows the owner to exercise the right to buy or sell the
underlying asset on or before the expiration date. 2) A European option contract allows the owner to exercise the right to buy or sell the
underlying asset on the expiration date only. In general, American options are more valuable, due to increased flexibility. Virtually all option contracts traded in the U.S are American option contracts.* *Exception is foreign currency options and stock index options traded in the CBOE
38
To estimate fair value of C or P: The Binomial Option Pricing Model (used for European) European options: Can be exercised only on expiration date / stocks pay no dividends American options: Can be exercised anytime during their life. BOPM can be used if modified / pays dividend $100
To value a call option: A portfolio with: Up Down Current price Stock 125 80 100 Bond 108.33 108.33 100 Call 25 0 ? Replicating the portfolio with appropriate combination of stock & bond can lead to a fair value of option EQ1: 125Ns + 108.33 Nb = 25 Up EQ2: 80Ns + 108.33 Nb = 0 Down (Ns: # of shares, Nb: bond) Ns = 0.5556, Nb = -0.4103 x 100 = $14.53 @ time: current V0 = 0.5556 x 100 – 0.4103 x 100 = $ 14.53 Buy stock Short sell bond V0 = NsPs +NbPb (Ps: $stock, Pb: $bond) Smart investor will recognize: once V0 is established then
1) If option overpriced say selling @ 20 the profit will be $5.47 (write the call for 20-14.53) 2) If option underpriced say selling @ 10 the profit will be $4.53( buy the call, short the
stock, invest in bond) 4.53 = [ -10 + (0.5556 x 100] – 41.03 Hedge ratio: the expected change in the value of an option for every $1 change in price of stock, the portfolio will change by Ns or 0.5556 The price of the Call will change by 0.5556 as well.

= Ln 107 = 1.886% Return for one week 105
LN: natural logarithm continuously compound return
Find 52 weekly returns n
Estimate stock’s Ave. return RAV = 1 ∑ (if 6 period - ) n
S2 = 1 ∑ 2 pre-period variance could be 1 week or one day n – 1
Variance: - 2 = 5252 - Some analysts give more weight to recent market value than historical data
Market consensus of a stock’s risk
Implicit volatility: Pc = Vc option priced fairly in market
Mkt $ = fair value
For same expiration date find 0 ex:
35 1
45 2
50 3
By using Vc = N(d1)Ps – E N(d2) formula or groups of diff. expiration date estimate eRT
See P695 Fig 206 for intrinsic call & time value of Black-Scholes value curve (Fig 208 for put)
Put call parity in Black-Scholes: Pp = E N(-d2) – Ps N (-d2) eRT
Pp = Pc + E – Ps eRT
Flex options: CBOE: contracts on indices (by institution), investor specify E&T
