Dear fellow CFA candidates/readers,

Thank you for visiting visiting WhitneyDiary CFA I Notes series,Â I have been using the notes below for my revision and have passed the CFA Level I on June 2018 Exam. Hereby, I share my notes with you and hope that they are helpful:

- Net Present Value (NPV) =Â âˆ‘{CF/[(1+r)^t]}

â†’ Calculated using opportunity cost, discount rate, expected cash flow, timing of expected cash flow from the project

â†’ IRR is not used to calculate NPV - a) Accept project with positive NPV;

reject project with negative NPV.

b) Mutually exclusive project: accept higher positive NPV project.

c) Accept project with IRR > required rate of return;

reject project with IRR < required rate of return. - Conflict between NPV & IRR [mutually exclusive projects]

a) Scale of investment may differ

b) Timing of cash flow may differ - Holding period return (HPR) = (Ending Value – Beginning Value)/Beginning Value

HPR = (Ending Value/Beginning Value) – 1

HPR = (Ending Value – Beginning Value + Cash Flow Received)/Beginning Value - Money-weighted return = Internal rate of return (IRR)

â†’ IRR on a a portfolio, taking into account all cash inflows & outflows

â†’ PV (inflows) = PV (outflows)

***Preferable performance measure if the manager has complete control over money flows into & out an account.** - Time-weighted rate of return = geometric mean return

â†’ Measures compound growth [compute HPR for each holding period]

â†’ Time-weighted rate of return = [(1+HPR1)(1+HPR2)^(1/2)]-1

*Denominator of the power is determined by the number of holding period

***Preferable measure as it is not affected by timing of CF.**

**â‡’ If funds are contributed to a portfolio before a relatively poor period, money-weighted rate of return tend to be lower than the time-weighted rate of return.** - Bank discount yield (BDY) = (D/F)Â Ã— (360/t)

*D = Difference between F & Purchase Price

â†’ Express dollar discount from F

â†’ Ignore opportunity to earn compound interest

*Additional Note: Add on rate (AOR) = (D/F)Â Ã— (365/t) - Holding Period Yield (HPY) = (P1 – P0 +D1)/ P0

HPY = [(P1+D1)/P0] – 1

HPY = D/Selling Price [T-billsÂ â†’ Price]

â†’ Total return an investor earns between purchase date & the sale or maturity date

â†’ Reflects non-annualized return an investor will earn over a security’s life.

HPY = [BDYÃ—(n/360)] / {1-[BDYÃ—(n/360)]}

HPY = rMMÂ Ã— (t/360)

HPY = (1+EAY)^(n/365) – 1 - Effective annual yield (EAY) = (1+HPY)^(365/t) – 1

â†’ Annualized value, based on 365-day year, that**accounts for compound interest**. - Money market yield (CD equivalent yield)

â†’ annualized HPY, assuming a 360-day year

a) rMM = HPY Ã— (360/t)

b) Given rBD, rMM = (360Â Ã— rBD) / [360 – (t Ã— rBD) - HPYÂ â‡” rMMÂ â‡” EAYÂ â‡” BEY

a) HPY = The actual return an investor will receive if the money market instrument is held until maturity

b) EAY = The annualized HPY on the basis of a 365-day year & incorporates the effects of compounding

c) rMM = The annualized yield that is based on price and a 360-day year & does not account for the effects of compounding – it assumes simple interest. - Bond Equivalent yield (BEY) = 2Â Ã— semiannual discount rate

BEY = [(1+EAY)^(t/365) – 1]Â Ã— 365/t

BEY = HPYÂ Ã— (365/t)

BEY = 2Â Ã— (YTM^0.5) – 1
