PROBLEM SETS
1. Answers to this problem will vary.
2. The dealer sets the bid and asked price. Spreads should be higher on inactively traded
stocks and lower on actively traded stocks.
3. a. In principle, potential losses are unbounded, growing directly with increases
in the price of IBM.
b. If the stop-buy order can be filled at $128, the maximum possible loss per
share is $8, or $800 total. If the price of IBM shares goes above $128, then
the stop-buy order would be executed, limiting the losses from the short sale.
4. (a) A market order is an order to execute the trade immediately at the best
possible price. The emphasis in a market order is the speed of execution (the
reduction of execution uncertainty). The disadvantage of a market order is that
the price it will be executed at is not known ahead of time; it thus has price
uncertainty.
5. (a) The advantage of an Electronic Crossing Network (ECN) is that it can execute
large block orders without affecting the public quote. Since this security is
illiquid, large block orders are less likely to occur and thus it would not likely
trade through an ECN.
Electronic Limit-Order Markets (ELOM) transact securities with high trading
volume. This illiquid security is unlikely to be traded on an ELOM.
6. a. The stock is purchased for: 300 × $40 = $12,000
The amount borrowed is $4,000. Therefore, the investor put up equity, or
margin, of $8,000.
