Formulas to Memorize Flashcards
Coefficient of Variance
Coefficient of Variation is a way to compare the relative variation of two or more securities. The security with the lowest CV should be chosen.
Standard Deviation divided by the mean (average). All other risk related formulas have risk (SD or Beta) measurment in the denominator and this forfula (Coefficient of Variation) has it in the numerator and has the retuns in the denominator.
CV = SD / Mean
Correlation Coefficient (R)?
Not provided but you can do algebra to get it from the Covariance Formua (which is provided)
COVij = R x σi σj
R = COVij / σi σj
R or rho equal the Correlation Coefficient
Valuation of Real Estate?
Property Value = NOI / Cap Rate
To get NOI, you have to Add all Operating Income to get Gross Operating Income (rent + laundry, etc.).
Then apply the Vacancy rate (usually about 7%, so you will multiply by 93% to get the Operating Income)
Then you will subtract all the costs like property taxes, property insurance, property management, utilities, administration, repairs, maintenance, etc. (No not include Financing Costs or Depreciation). This number will give you your NOI.
Risk adjusted return using Beta?
Risk Adj = Mean / Beta
Growth Rate
This is used in the Discount Dividend Model
g = ROE x RR -or- ROE = g / RR
g = growth rate
ROE = Return on Equity (ROE is calculated by net income / shareholders equity)
RR = Retained Rate of Earnings => the remaining percentage is the Dividend Payout Rate, so if the RR = 80%, then the company paid 20% in Dividends.
RR = To calculate Divedend payout ratio => take Dividend / EPS = Payout then take (1-payout ratio ) to get Retained Earnings.
EPS = Divide current dividend by the dividend payout ratio (expressed as a decimal)
P/E = Divide price per share by the earnings per share
Taxable Equivalent Yield for Federal and State Tax
TEY = Tax Free Yield / (1-Federal) x (1-State)
DDM formula
V = D1 / (r - g)
V = Intrinsic Value
D1 = Next year Dividend Rate [D1 = D0 x (1 + dividend growth rate)] or D1 = $1.50 (1 + 4%) so D1 = $1.50 (1.04) or $1.56
r = required rate of return
g = growth rate of stock
DDM Formula for Non-Constant Rates of Growth?
Earnings and dividends per share are expected to grow at a rate of 18% over the next three years, and a constant rate of 6% thereafter. The last dividend was $1.15. The required return is 12%. What is the price of the stock today? This is done in 3 steps.
Step 1: What is the dollar amount of the dividend at the end of the each of the first three years?
Year 1: 1.15 x 1.18 = 1.3570
Year 2: 1.3570 x 1.18 = 1.6013
Year 3: 1.6013 x 1.18 = 1.8895
Step 2: What is the value of the stock at the end of Year 3 based on the dividend at the end of Year 4? Use Constant Growth Formula here.
[1.8895*(1.06) / 0.12-0.06] = 33.380
Step 3: What is the discounted value today of the stock price and the dividend at the end of Year 3 and each of the dividends for years 1 and 2?
Use calculator and solve for NPV as an irregular cash flow:
Entry Keystrokes
12 I
0 CFj0
- 3570 CFj1
- 6013 CFj2
(1. 8895 + 33.3809) = 35.2704 CFj3
SHIFT, NPV = 27.59
Expected Return vs. Required Return
Expected Rate of Return Formula on the Exam Sheet is
r = (D1 / P) + g
Need to write the Capital E on the formula sheet and title it Expected Return
Er = (D1 / P) + g
Required Rate of Return Formula on the Exam Sheet is
ri = rf + (rm - rf)βi
Need to write Required Rate of Return on the formula sheet
Alimony Recapture Formula
P1 + P2 - 2P3 - $37,500 = Alimony Recapture
P1 = Payment in year 1
P2 = Payment in year 2
P3 = Payment in year 3
Tips when making calculations for PV/FV and CF
PV/FV: Create Write a timeline to track Int Rate and Inflation to make sure that it is balanced. Especially in 3 part college tuition question.
PV/FV: Create a table with B/E - N - I/YR - PV - PMT - FV
CF: Write a table for Cash Flows and write a timeline with positive numbers on top and negagive numbers below timeline. Make sure to be in the correct term (monthly, semi-monthly, quarterly, yearly). Make sure to use $ signs and % where available so I track what is going on better.
Write out the Units ($ or %) explicitly
How do I calculate the Price of when a Margin Call will occur?
Question:
An investor wants to buy 100 shares of a stock on margin. The stock is selling for $40 per share. The initial margin is 55% and the maintenance margin is 35%. Assuming she can purchase the stock at the current market price, at what price will a margin call occur?
The formula is [(1 − initial margin) / (1 − maintenance margin)] × price of stock = margin call price.
Answer:
the formula is [(1 − .55) / (1 − .35)] × 40 = 27.69
Margin Price Formula?
(1 - Initial Margin Rate / 1 - Maintenance Margin Call) x price of stock
Example:
Margin Rate is 50%
Maintenance Margin Percent is 30%
Price of Stock is $40
[(1 - 0.50) / (1 - 0.30)] x 40 = $28.57
How do you calculate the Price of a Convertible Bond?
Conversion Value = [($1,000 / Conversion Price) x Market Price of Common Stock
Example:
Zim Convertible Corp Bond at 9%
Comparable Debt Yields are at 8%
Zim Converrible Corp Bond Conversion Price is $40
Zim Corp Stock Price is $46
[(1,000 / 40) x 46 = 1,150
HO - Property Insurance calculation when underinsured?
[(insurance carried / insurance required) x loss] - deductible = maximum amount of recovery
* Coinsurance requirement is usually 80% of replacement cost. This is primarily a concern in the event of a partial loss.
Ex: Question
Andrew purchased an automotive service station seven years ago for $500,000. The building’s current replacement value is $900,000. Andrew originally insured the building for its replacement cost of $500,000 and has not increased the coverage. His policy has an 80% coinsurance clause and a $5,000 deductible. Last week a fire caused $200,000 of damage.
Payment = ((Amount of insurance owned/Amount of insurance required) × Loss) - Deductible
Amount of insurance required = $900,000 × .8 = $$720,000
(($500,000/$720,000) × $200,000) − $5,000 = $133,889
