2 Example GAP Variance Std Dev.
- Given the three annual returns on GAP stock,
calculate the mean, the variance, and the
standard deviation of the stock return. - Draw the probability distribution of the stock
return. - What is the return range within you expect the
return to be with 95 probability?
3 Example GAP Variance Std Dev.
Variance (Var) 2396.27/21,198 (in squared
percentage) Standard Deviation (Std. Dev.)
34.61 With 95 Prob. the expected return range
2 Std. Dev. range from the mean 12.15 (2 x
Std.Dev) - 57.07 and 12.51 (2x Std. Dev)

4Review Total return
- A stock had a price at the beginning of the year
of 48.20. You sell the stock after 6 months.
During this investment period you received 1.15
dividend on this stock. - If your total percentage return was -8.15 what
was price of the stock at the end of the sixth
month? - What is the EAR on this investment?
- EAR(1holdingret)m-1 (1-.0815)2-1 -15.6

Begprice return Div yield Capital gains

capital gains yield (CGY) ? thus, CGY
-10.54 Now, if CGY-10.54 (P1-P0)/P0 , we can
solve for P143.12
5Review Forecasting return
- You find a stock that has a geometric return of
10.2 percent and an arithmetic return of 12.4
percent over the past 30 years. - What is your best estimate of the annual return
over the next 15 years?
11.34
6Review IBM Margin accounts (1)
- You have 30,000 in a margin account that
requires 60 initial margin. - You can buy _______ of stock with this account.
- Your borrowing rate from your broker is 6.00.
- Suppose you buy 500 shares of IBM, for
100/share. - Assume no dividends, and that your borrowing rate
is still 6.00, what is your return if - In one year, IBM stock is selling for 110 per
share? - In one year, IBM stock is selling for 110 per
share, but you did not borrow money from your
broker?
50,000
7Review IBM Margin accounts (2)
- A) Now, the IBM stock is selling for 110 per
share (10 increase). - Your investment is worth 55,000.
- You owe 6 interest on the 20,000 margin loan,
that is ______. - If you pay off the loan with interest, your
account balance is 55,000 _____________
_______. - You started with 30,000 while your income (gain)
is 3,800. - Thus, the returns is 3,800, while the
return is - Income/ Investment ________ / 30,000
_____. - Suppose IBM stock was selling for 90 per share
instead of 110 per share? What is your return?
1,200
(20,000 1,200) 33,800
(3,800 ) 6
8Review IBM investment (3)
- B) IBM stock is selling for 110 per share, but
you did not borrow from your broker. - You started with 30,000, which means you were
able to buy ______ shares (recall original price
was 100). - Your investment is now worth (IBM trades at 110)
_________. - The return on the investment without margin
- Therefore, your return is __________________.
-
- Suppose IBM is selling for 90 share instead
of 110 per share. What is your return in this
case?
300
33,000
3,000/30,000 10
Recall that return gain/investment, here gain
is 6,000
9Review of margin purchases
- You purchase 200 shares at 45 per share. You put
up 5000 and borrow the remainder. Show your
balance sheet. What is your initial margin?
Suppose the maintenance margin is 35. - A) If the stock price falls to 35, what is your
margin? - B) At what price would you receive a margin call?
- See answer on the next slide.
- To answer part B, you use the formula P for long
positions from the formula sheet. - P 4,000/200 /.65 30.77.
- Thus, if the price declines to 30.77 then there
is a margin call.
10Review of margin purchases contd
Orig. balance sheet
- You purchase 200 shares at 45 per share, that
cost 9,000. However, you put down only 5,000
in cash, thus you borrow 4,000 from your broker.
Thus, initial margin is 5,000/9,00055.5. - If the price falls (from 45 to 35), then the
value of the 2,000 shares declines from 9,000 to
7,000. The margin loan (you always have to pay
back the 4,000) does not change, thus on the
right side of the balance sheet the equity value
declines. - New Equity New total value of shares Loan
7,000 - 4,0003,000. - The new margin equity / total shares value
3,000/7,00042.8
11Review of short sales
- You sell short 500 shares at 30 per share. The
initial margin requirement is 50 and the
maintenance margin is 30. - Show your initial balance sheet.
- What happens if the price rises to 35 per share?
- What price would trigger a margin call for you?
- See next slide
- See next slide for calculating new equity and
return - To answer part C, use the formula P for short
position. - P 22,500 / 500 / 1.3 34.6
12Review of short sales contd
Original balance sheet
- A) The short proceeds 500 shares sold at 30
15,000 - The margin if 50 of the short proceeds 50
15,000 7,500. - B) If the price rises to 35 you are losing money
because you have a short position and the price
decline is not beneficial for you. You likely
entered the short position because you expected
price decline. - The new value of the equity position Total
Short positions 5,000 - You originally put down 7,000. Now you have
5,000, thus you lost about 33.33

fund makes a dividend distribution of 0.18 and a
capital gains distribution of 0.38. If the NAV
at the end of the year is 36.21, what was your
return for the year? - Here, we assume that you bought 305 shares.
- Solution
- Income per share (36.21-32.80).18.38 3.97
- On the 305 shares you earn 3053.971,210.85
- Return Income / Investment 3.97/32.80 12.1
20Review MMMF tax effect
- A non-taxable money market mutual fund has a
return of 2.8 percent. If you are in a 36 percent
tax bracket, what is the return you would require
on a taxable fund? - If you can earn 4.8 on a taxable fund (and your
tax bracket is 32) when would you prefer a
nontaxable fund (with what return)?
2.8 X(1-36) where X is the return on
taxable fund 2.8 / (.64) X
4.375X You need to earn 4.375 before tax
return to have 2.8 after tax return.
After tax return (on 4.8) 4.8(1-32) 3.26
You should prefer any nontaxable fund that offers
return higher than 3.26.
