that is the “optimal” composite blend of Motorola and RIM stocks. Solve for the optimal fraction of this portfolio that
will be in US 30day TBills, Motorola and RIM stocks. Show all calculations and state all assumptions.
Hint: ❶ Construct the optimal “blend” of Motorola and RIM stocks ❷ Construct a portfolio of US 30 day Tbills and the
“blended risky asset”.
(e) Suppose
. Suppose this investor wants to invest in a portfolio consisting of US 30day TBills and a “risky” asset
which is that composite blend of Motorola and RIM stocks which minimizes the risk of the “risky” asset. Solve for the
optimal fraction of this portfolio that will be in US 30day TBills, Motorola and RIM stocks. Show all calculations and
state all assumptions.
Hint: ❶ Construct that “blend” of Motorola and RIM stocks which minimizes the risk of the “blended risky asset” ❷
Construct a portfolio of US 30 day Tbills and the “blended risky asset”.

(7.1) For this question you’ll need to download data for a “risk free asset” and two “risky assets”: US 3month TBills and
Dell and Boeing stocks.
Here’s what you need to do to get data on US 3month TBills and Dell and Boeing stocks: Go to http://dc1.chass.utoronto.ca/ and then CRSP (if you’re off campus you’ll need to log in with your UTORid)
Go to Advanced search
Choose Monthly tables (this is because daily tables, by definition, do not contain dividend yields)
Search for Keywords “Dell Boeing” (string in company name, and match any keywords)
Select Dell and Boeing and “copy to my companies list”
In Select one or more companies ”Select all” and continue
In “Monthly Tables” select: Lowest bid price, highest ask price, closing price, volume shares traded, Returns, and
Returns without dividends
In “Output format” select “MS Excel Ready” and continue
The Excel spreadsheet will contain Boeing data from Sept 29th 1934 onwards and Dell data from June 30th 1988
onwards, both until December 31st 2011.
In a separate worksheet, download 3month US Tbill daily interest rates from Federal Reserve St. Louis
http://research.stlouisfed.org/fred2/series/TB3MS/downloaddata?cid=116 . Transform this data from
percentages into “out of 100” decimal places
Create a single worksheet with Boeing, Dell and TBill interest rates data from June 30th 1988 onwards. Arrange
individual stock data in the following order: Volume, High price, Low price and closing price. (a) Use Excel’s built in “stock chart tool” to plot Dell and Boeing’s Volume, High price, Low price and Closing price. Answer
Please see Excel Model Chapter 7.1.
(b) The return on an asset between time and ⏟ is defined as: ⏟ CRSP gives the “holding period return” (i.e. ) and “return without dividends” (i.e. capital gains). Calculate Dell and
Boeing’s dividend yield and dividend for each month in the sample. What do you notice about Dell’s dividends (Finance
and accounting majors: read this article)?
Answer
Please see Excel Model Chapter 7.1.
Dividend Yield (or gain) is calculated as:
Dividend Yield = Return – Return without Dividend
Once we have dividend yield, the...
