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 margined position (assuming again that you invest $15,000 of your own money) if Intel is selling after 1 year at: (i) $44; (ii) $40; (iii) $36? 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?

A: (i) 4*500/15000=13.3% (ii) 0 (iii) -4*500/15000=-13.3%
The relationship between percentage return and percentage price change is

Percentage return= percentage price change*total investment/investor’s initial equity

B: (500P-5000)/500P=25% so when the price is $13.3or lower, investors will get a margin call.

C: (500P-10000)/500P=25% so when the price is $26.6 or lower, investors will receive a margin call.

D: (i) (4*500-5000*0.08)/15000=10.67% (ii) (0-5000*0.08)/15000=-2.67% (iii) (-4*500-5000*0.08)/15000=-16%

The relationship between percentage return and percentage price change is

Percentage return=percentage price change*total investment/initial investment of one’s own-8%*initial borrowing/investor’s initial equity
E:
(500P-5000*1.08)/500P=25% so when the price is $14.4 or
