Answer Key

 

1. C
The question is trying to confuse with irrelevant details. The fact that the couple wanted to buy the bond for $2,000 does not matter. What matters is they bought it at $2,050. The next year when they decide to sell, the value of the bond has depreciated from $2,050 to $2,000. The return from selling the bond would reflect the interest earned minus the depreciation caused by the fall in market value. The bond earned 10% but lost almost 2.4%, which means it delivers a return of 7.6%.

($2050-$2000 = $50)/$2050 x 100 = 2.4%. (10% + (-2.4%) = 7.6%

2. A
The return on investment on a bond depends on the interest rate, which is 12% in the case. The total return must however reflect any addition or subtraction caused by an appreciation or depreciation of the bond’s value. In this example, the bond depreciated from $1,000 to $950. The percentage lost is ($1,000-$950 = $50)/ $1,000 x 100 = 5%. Since the bond pays 12% interest, total return on this investment is 12%-5%= 7%

3. D
Since the complete account information is provided, we can easily calculate equity using the formulas for long and short account

Long account: Current market value – debit
Short account: Credit – Market value short = equity
Long account = (400 x 60)$24,000 – $12,000 = $12,000
Short Account = $17,000 – $8,750(250×35) = $8,250

Total equity in account = $12,000+$8,250 = $20,250

4. B
The mutual fund earned 30% on $1,000 in the first year, which is $300. That means the mutual fund was worth $1,300 at the end of the first year. In the second year, it now lost 15% on $1,300, which is $195. The value of the mutual fund at the end of 2 years is $1,300-$195= $1,105

5. A
To calculate HPR or Holding Period Return, we use the formula: Total Return divided by the Total Cost of investment. Total return is calculated by adding all dividends, income, appreciation and deducting depreciation and margin interest. In this case, the total return is $7,500 (proceeds) + $300 (dividend) – $6,000 (Cost) = $1800. So, HPR is $1800/$6000 x 100 = 30%

6. C
Interests and earnings accrued from U.S government bonds are not subject to state or local taxes. They are not, however, exempt from federal taxes. This makes it important for investors planning to invest in a taxable or non-taxable investment, to first calculate the tax-exempt yield. A tax-exempt yield would only be considered attractive if its yield is above 4.9%

The formula to compute tax-exempt yield is to take the taxable-equivalent Yield and multiply it by (1-Marginal tax rate) which equals the tax-exempt yield.

In this case, 0.1 x (1-0.25)= 0.075 or 7.5%

7. D
The current market price of the stock is $50, so the stock is presently overvalued. The current market price is calculated using = earnings times P/E ratio. In this case, $2.50 x 20 = $50

8. C
The question contains some information that is not relevant in calculating annual interest on income. The par bond is worth $1,500 and its offers a 10% coupon. This simply means that the annual interest is 10% of $1,500, which is $150. The maturity date or present selling price does not affect the calculation of yearly interest.

9. B
This is a long margin account. Formula for calculating equity on this account is: CMV-DR=EQ

CMV = $7,500+$8,000+$9,000 = (24,500 CMV – 10,500 DR = 14,000 EQ).
To calculate the EQ or equity required, we multiply CMV by 50%
50% of $24,500 is $12,250. So this account has excess equity.
