In which, K(m) of each DM = Each DM ' s contribution Total SCF − Contribution of DM C = 120 600 − 120 =0. -> Each of the other DM’s supporting amount = 0.25x 40m = 10m/DM
Next, let's calculate the total value of your investment after the price increase. Total Value = New Price * Number of Shares Total Value = $55 * ( $10,000 / $50 ) Total Value = $11, You borrowed $5,000 at an interest rate of 8%, so you owe your broker the following amount: Amount Owed = Borrowed Amount + (Borrowed Amount * Interest Rate) Amount Owed = $5,000 + ($5,000 * 8%) Amount Owed = $5, Finally, let's calculate your rate of return. Rate of Return = (Final Value - Initial Investment - Amount Owed) / Initial Investment Rate of Return = ($11,000 - $5,000 - $5,400) / $5, Rate of Return = 12% So, if the price of Telecom stock goes up by 10% during the next year, your rate of return will be 12%. b. Price Fall for Margin Call A margin call happens when the equity in your account falls below the maintenance margin. Equity is the current market value of the stock minus the amount borrowed. The maintenance margin is the minimum percentage of the total market value that the equity must be. Let's denote the price at which you get a margin call as P. The equity in your account when the price falls to P is: Equity = (P * Number of Shares) - Amount Borrowed The total market value when the price falls to P is:
Total Value = P * Number of Shares You get a margin call when the equity is 30% of the total market value, so: (P * Number of Shares - $5,000) / (P * Number of Shares) = 30% Solving this equation for P gives: P = $5,000 / (Number of Shares * (1 - 30%)) P = $5,000 / (200 * 0.7) P = $35. So, the price of Telecom stock has to fall to $35.71 for you to get a margin call. (THAO PHUONG)Ex2: Suppose that Intel currently is selling at $20 per share. You buy 1,000 shares using $15,000 of your own money, borrowing the remainder of the purchase price from your broker. The rate on the margin loan is 8%. a. What is the percentage increase in the net worth of your brokerage account if the price of Intel immediately changes to: (i) $22; (ii) $20; (iii) $18? What is the relationship between your percentage return and the percentage change in the price of Intel? b. If the maintenance margin is 25%, how low can Intel’s price fall before you get a margin call? c. How would your answer to (b) change if you had financed the initial purchase with only $10,000 of your own money? d. What is the rate of return on your marginal position (assuming again that you invest $15,000 of your own money) if Intel is selling after 1 year at: (i) $22; (ii) $20; (iii) $18? What is the relationship between your percentage return and the percentage change in the price of Intel? Assume that Intel pays no dividends. e. Continue to assume that a year has passed. How low can Intel’s price fall before you get a margin call? Solution:
● Case 3: Price decreases to P=18: Stock value = 18×1,000 = 18, Equity= Stock value−Loan balance= 18,000 − 5,000= 13, Percentage change= New Equity − Initial Equity Initial Equity
13,000−15, 15,
Relationship: The relationship between your percentage return and the percentage change in the price of Intel is that they are inversely proportional. When the price of Intel increases, your percentage return decreases, and vice versa. This is due to the fact that you are leveraging your investment with borrowed money, so changes in the stock price have a magnified effect on your net worth. b) Equity = Stock value − Loan =1,000 P − 5,000⋅ The maintenance margin is 25%, so: Equity / Stock value ≥ 0. => 1,000 ⋅ P −5, 1,000 ⋅ P
The stock price must not fall below $6.67 to avoid a margin call. c) new Loan=20,000−10,000=10,000. Equity / Stock value ≥ 0. => 1,000 ⋅ P −10, 1,000 ⋅ P
New margin call price: $13.
d) Loan interest = 5,000 × 8%= 400 ● Case 1: P= Stock value = 22×1,000 = 22, Equity = 22,000−5,000−400=16, Rate of return = 16,600−15, 15,
● Case 2: P= Stock value = 20×1,000 = 20, Equity = 20,000−5,000−400=14, Rate of return = 14,600−15, 15,
● Case 3: P= Stock value = 18×1,000 = 18, Equity = 18,000−5,000−400=12, Rate of return = 12,600−15, 15,
Relationship: The percentage return on equity is amplified compared to the percentage change in the stock price due to leverage. This means that small changes in the stock price result in larger percentage changes in equity, both positively and negatively. e) Loan = 5,000 × (1+8%) =5 ,400. Equity / Stock value ≥ 0. => 1,000 ⋅ P −5, 1,000 ⋅ P
New Margin Call Price: P=7.20 $/share
Profit = 1377.2 mil - 1.2 bil = 177.2 mil Rate of return = 177.2 mil / 1.2 bil = 14.77% (KHUÊ)Ex 4: Information about contribution of each depository up to the time of using the Settlement Compensation Fund as follow: Unit: USD mio Member A B C D E F Contribution 240 350 150 400 300 500 Clearing result on 6/8/N, member A has to pay 600mio but A has 100mio on A’s account.
