Suppose you wish to short-sell 100 shares of MNO stock, which has a bid pric of $44.22 and an ask price of $46.42.

Suppose that there is a 0.4% Commission to engage in the she t—saie and a 0.3% commission to close the short-sale. Suppose the lender keeps the entire proceds from the short sale as collateral... (a) What profit did you make? (13) Suppose the 9—month interest rate is 6%, and that the rebate for MNO stok offered by the lender is 2%. How much interest accrues during the 9 months in which you have the short position? Does this reduce or increase your profit? 10. Do an'ohline search of the term “hard to borrow.” In the contest of. short—sale, what does this mean? u—u—m. .r-"" Chapter 1 I. i . U1 Introduction to Derivatives (a) The airline industry is a very good example. Theprofit of an airlite company is severely affected when the price of oil is rising. Passengers oftentimes bu tickets in advance. and sudden price increases for keroseoe cannot be passed on to the passenger if a contract pays off iii tie-res of higher crude oil prices. airline companies can hedge their eapsure to the oil price risk. ' (b) An example would be countries whose principal revenues stem tom oil export. Their revenues are severely hit if the price of oil declines. Any contract that pay. off in times of declining oil '- prices would be attractive to them. it ' - Note that speculators are also very active in the crude oil market. The drastic increase ira- crude oil prices that we witnessed in July 2.004 was rumored to-he parti lly driven by speculators hoping for ruptures in supply of crude oil. ' One ot‘the problems with wine is that it is much less standardized. Y a can set exact quality standards for crude oil. and market participants know and respeCt the 'e standards. The wine futures contract traded at the exchange promised to deliver at the end of the ontract five cases of wine that the seller could choose from a wide list of estates that were classified based on the French ' classification system of 1855. However. there could be large differen es in the development of prices for different estates. This made trading complicated. because a was not absolutely clear what _ would eventually be delivered. " The concept of standardization is very important. In later chapters. th book will deal more detail with the problem”; of standardization and delivery. Broker A: ($98.20 >< 100) + ($98.20 x 100) X 0002 + $5 = 3; £44.64 Broker B: ($98.20 >< 100) -+ $30 = sassooo You should buy the shares from broker A. because‘yoor total outhof— ocket expenses are smaller.

Now you should boy from broker B Proportional transaction costs are cheaper for sitiall quantities. That is why you__ofteh see advertiser} eats such as “We charge 0.5%.

Therefore. the price at which you can buy is called the ask price. Yot pay: ($50.25 x 50) + s15 : $2527.50 You can sell at the market maker’s bid price. You will have to pay a I elm-mission. and your broker will deduct the commission from the sales price of the shares. You raise: .(bidx50)-—s15 60 McDonald 1? Derivatives Markets. Second Edition Your round-trip transaction costs amount to: 57.50 2 $2,527.50 —— (bid X 50 an $15) 22> bid = $49.70 W e need to take into account the increase in the quotes after our trade was excnted. This has an influence on the roundtrip transaction costs. Why should the bid and ask increse after we buy the stock? If the stock is very illiquid (Le... it is rarely traded). our purchase might “ignal that we have good news about the development of company XYZ. and the market maker ra .ses the price to take into account this conjecture. TAC = $51.37 x 10 + $10 -— ($51.25 x10 m $10) = $21-20 Oar transaction costs are smaller than without an increase in the quotes. Remember that the market maker can buy at the bid and sell at the ask—that '. how he makes a profit for the provision of liquidity. Therefore. Profit of Market Maker : $51.37 X '10 — $51.25 X 10 = $1.20 Despite the increase in quotes agaiast him. the market maker is able to make :- profit. A short sale of MNO entails borrowing shares of MNO and then selling them t the bid. Therefore, initially. we will receive 200 x ($12.32) = $2,404 The counterparty will keep that amount. but requires an additional 20% as a hircut. Therefore. we will have to transfer 020 x $2.464 2: $492.80 to her. (a) A short sale of MNO stock entails borrowing shares of MNO and then sel ing them. receiving cash. and we learned that we sell assets at the bid price. Therefore. initiall . . we will receive the proceeds from the sale of the asset at the bid (ignoring the commissions a d interest). After 270 days. we cover the short position by buying the MNO stock. and we saw t at we will always buy at the ask. Therefore. we earn the following profit: 100 x ($44.22) — 100 x ($44.22) x 0.004 _ (100 x ($49.05) ><: 0.003 + 100 ($49.05)) .—-= $4,422 x 0.996 —-— sages x 1.003 = $4.4043 '1 — $5,052.15 = ——$6 7.84 Therefore. we actually made a ioss of $647.84. The stock price rose durin ;_ the life of the short sale. and with rising stock prices. a short position loses money. (b) The proceeds from short sales, less the commission charge are $4.4043l. Since the 9flmonth interest rate is 6%. but the lender only offers 2% on our collateral. we 103 an additional $4.40431 X 0.04 2 $176.17.
