Investments Flashcards
Holding Period Return =
Profit / Cost
Dollar weighted
Use only with CFs: CF-0, CF-j, f-IRR
Time weighted
Chain ‘em together
Systemic Risk
Risk you can’t diversify. Measured by beta (R2 < 70%).
Unsystemic risk
Firm risk: business, financial, default, regulation, country
Standard Deviation
Enter the number followed by the Sigma + key. Then and g-s.
Skewness: Meso, Lepto, Platy
Meso normal
Lepto skinny
Platy fat and flat
Sharpe formula
(Rp-Rf)/SDp. Used when R2<70%. Use if not given R2.
Treynor formula
(Rp-Rf)/Beta. Use when R2>70%. This is a relative measure and you use it when comparing 2+ investments
CAPM
Rf + (Rm-Rf)*Beta
Jenson’s Alpha
Rp - [Rf + (Rm-Rf) X beta]
Nominal yield
Coupon yield
Current yield
Income / Price
Duration
Weighted avg of future CFs stated in years
Always shorter than maturity
Convexity
change in bond price = (Duration X %rate change) / (1+YTM)
DDM: FV Stock with constant growth rate
(Div X g) / (r-g)
DDM formula
CF-0 = 0
CF-1 = Div x g1
CF-2 = CF1 x g1
CF-3 = CF2 x g1 + (CF2 x g X g2)/(r-g)
Margin call price
(1-initial) / (1-maint) X purchase price
Maintenance margin
How much equity you must maintain in the account value. Usually 30-40%.
Initial margin
How much they’ll loan you as a % of the equity in your account. 50% is normal.

Futures: long hedge
Short the commodity, buy the futures contract.
NPV calc on 12C
CF0, CFj, and Nj
IRR on calc
N, PV, FV, PMT, i
When is NPV better?
Comparing projects with unequal lives
Investing at ROR is more reasonable than at the IRR
You can get multiple IRRs with IRR calc
Wash sale days?
30 before and 30 after. 61 days
Wash sale cost basis rule?
If you don’t get the loss, you can add that amount to your cost basis of the stock you just bought.
