A STEP-BY-STEP GUIDE TO PROJECT 2(04)
Project 2(04): Construct a one-month-holding-period financial portfolio in February 2023 with:
Fraction 1 − of funds invested in a “Risk-Free Asset”
Fraction of funds (with ≥ 0) invested in a “Synthetic
Risky Asset” (SRA) which consists of four risky assets with
investment weights 1, . . , 4 ( ⋛ 0 and σ = 1)
1 in “Equity #1” 2 in “Equity #2”
3 in “Equity #3”
OR “Oil”
4 in a
“Corporate-
Bond”
• You are the CIO at a “family-fund”.
• This morning (“today” = Jan 31st 2023), the (risk-averse) Board of Directors (Ivey &
Queens graduates) put you in-charge of Project 2(04):
• Project 2(04) harkens back to time you took ECO204 and aced the “Shred Ivey-
Queens Project” by constructing a financial portfolio by four different methods.
• You’re going to prove your mettle – and once again shred those Queens & Ivey
snobs – by constructing four different models of the Project 2(04) financial portfolio. 2

Portfolio C
Use Portfolio A algebra by
treating SRA as “the” risky asset
Recall: The “Algebra” of Constructing Portfolio of a Risk Free and Synthetic Risky Asset
For the sake of illustration,
suppose the SRA consists
of 3 risky assets
Calculate optimal investment weights of risky assets in
SRA by maximizing the SRA’s Sharpe Ratio
Calculate optimal fraction invested in “risk free asset”
and “SRA as the risky asset” (with return-risk and
) by maximizing Mean-Variance Utility.
In practice, you’d need the value of parameter [see W12
Lecture, W14 Tutorial]

FRED Series DGS3MO
• Download monthly data via FRED Excel Add-in or FRED website. See FRED-DGS3MO tab and W14 Tutorial on how to
transform FRED data to obtain monthly (by “compounded method”) in Feb 2023.
• By definition: = 0, = 0 for all = 1, . . .
CRSP “Equities”
• See Equity-Bond-Assign tab for CRSP equities assigned to you and download data from CRSP.
• Currently, CRSP reports “returns” through June 2022. See Lecture Delivered W11 on “cleaning” and “pruning” CRSP
data for a common “date range” (see Equities-CRSP-Jun22 tab for demo example).
• For July 2022 – Jan 2023 “data”, use Google Sheets in Equities-Google-Jan23 tab to download “daily prices”
assume no dividends calculate monthly −1, =
−−1
−1
[Urge you to look at the Excel “setup” and “formulas”]
• Combine CRSP and Google equities data sets (see Equities-Data tab).
S&P500
• For reasons to be explained later, we will need data on SP500 returns.
• Best option is to download SP500 Nominal Index from multpl.com and compute returns for the date range of the “final
equities” data set (See Lecture Delivered W11 and SP500 tab)
“Corporate-Bond”
• Download the Blackrock-IBHC-ETF file (updated daily) from here “clean/format” the data (see Blackrock-IBHC-
ETF tab) Extract the row corresponding to your bond copy & paste & transpose that row in new worksheet
(see DEMO-Sprint tab)
• Use the bond’s ISIN # to find “today’s price” (be creative and put some elbow grease).
• Use “Solver” to compute a “finely-tuned” YTM monthly rate (see Table in Columns H-L in DEMO-Sprint tab).
• Research your corporate-bond rating (AAA, AA, A, B, BB, BBB, CCC) Go to Corp-Bonds-Quandl tab and take
note of data-series (monthly yields) corresponding to your bond rating
“Commodity -- Oil”:
FRED Series
DCOILWTICO
• NOT in Excel-Template. Download monthly data of Oil prices ($/barrel) via FRED Excel Add-in or FRED website
Forecast next month’s Oil price by assuming growth rate of Oil prices is Normally distributed and “picking” a growth
rate at random from this distribution (see Gold Claims Case)
Combine the final equities returns data set, SP500 returns data set, Quandl-Bond monthly yield data series corresponding to your bond’s rating,
and the Oil returns data set, over the date range of the “final equities” data set to obtain a “unified” data set (see ALL-DATA tab).
