3. What is an efficient market?

4. If you did not wish a high-priced or heavily capitalized firm (one with high total market value) to overly influence your index, which of the weighting systems described in this chapter would you be likely to use?

5. You sell 100 shares of Norton Corporation short. The price of the stock is $60 per share. The margin requirement is 50 percent.

a) How much is your initial margin?

6. Assume the following five companies are used in computing an index:

a) If the index is price weighted, what will be the value of the index on December 31, 2007? (Take the average price on December 31, 2007, and divide by the average price on January 1, 1984, and multiply by 100.)

b) If the index is value weighted, what will be the value of the index on December 31, 2007? (Take the total market value on December 31, 2007, and divide by the total market value on January 1, 1984, and multiply by 100.)

c) Explain why the answer in part b is different from the answer in part a
