Indexes
If you have insight into the future direction of the stock market, specifically one index or another, you may want to trade stock index futures.
Stock index futures allow you to make a bet on which direction you think a stock market index is headed.
Stock index futures also allow you to hedge various financial positions.
Stock index futures trade on a number of different indexes.
Chapter 9 3
Indexes
The various indexes use differing computational methods. To understand the trading and pricing of index futures, one must first understand a bit about how the underlying indexes are computed.

Chapter 9 4
Priced-Weighted Indexes
In a price-weighted index, stocks with a higher price receive a larger weighting in the computations.
Price-weighted indexes do not consider dividends paid by the stocks.
The companies contained in these indexes change infrequently. Changes only occur as a result of special events like liquidations and mergers.
In this section, the DJIA is used as a representative price-weighted index. The DJIA is comprised of 30 stocks. Table 9.1 shows the lists of stocks.

Chapter 9 6
Priced-Weighted Indexes
The DJIA is computed by adding the share prices of the 30 stocks comprising the index and dividing by the DJIA divisor. The divisor is used to adjust for stock splits, mergers, stock dividends, and changes in the stocks included in the index.
Index Divisor
The index divisor is a computed number that keeps the index unchanged in the event of certain occurrences (e.g., dropping one company from the index and adding another company, mergers and stock splits).
The DJIA can be computed by using the following formula:

Assume that the Dow Jones company decides to delete Boeing from the index and replace it with Dow Chemical. Boeing stock trades at $6.00 and Dow Chemical trades at $47. The current level of the index is 1900.31 with a divisor of .889.

Thus, to keep the index value unchanged, the new divisor must be 0.9106.
If the divisor is not changed the DJIA will be 46 points higher as a result of the component change. Thus, a new divisor must be calculated.

Market Capitalization-Weighted Indexes
Each of the stocks in these indexes has a different weight in the calculation of the index. The weight is proportional to the total market value of the stock (the price per share times the number of shares outstanding).
The value of the S&P 500 index is reported relative to the average value during the period of 1941-1943, which was assigned an index value of 10.
Assume that the S&P 500 index consists of three stocks ABC, DEF and GHI.
Table 9.2 shows how the value of these 3 firms will be weighted.

Note: Some stock index futures trade on both U. S. and non-U.S. exchanges, and some non-U.S. markets dominate in certain contracts.
As Table 9.3 shows, the total value of a futures position depends on the currency, the multiplier, and the level of the index.
Chapter 9 14
Stock Index Futures Contracts
The contract size is computed by multiplying the level of the index by the appropriate multiplier.
Example
Assume that The DJIA is 11,000 and the multiplier for the DJIA futures contract is 10. What is the value of a given contract?
The futures product has a contract value of:
11,000 X $10 or $110,000
Now, assume that DJIA goes up to 11,250. What is the value of a given contract?
The futures product has a contract value of:
$10 X 10,250 = $112,500
One point change in the DJIA results in a $10 change in the value of the futures contract.
Notice that price changes for a contract depend on the contract size and volatility of the index.

Chapter 9 19
Stock Index Futures Prices
Stock index futures trade in a full-carry market. As such, the Cost-of-Carry Model provides a good understanding of index futures pricing.
Recall that the Cost-of-Carry Model for a perfect market with unrestricted short selling is given by:
)1( ,00,0 tt CSF
Applying this model to stock index futures has one complication, dividends.
If you purchase the stocks in the index, you will receive dividends. Recall that most indexes ignore dividends in their computation, so the Cost-of-Carry Model must be adjusted to reflect the dividends.
The receipt of dividends reduces the cost of carrying the stocks from today until the delivery date on the futures contract.
Chapter 9 20
Stock Index Futures Prices
Today, t0, a trader decides to engage in a self-financing cash-and-carry transaction. The trader decides to buy and hold one share of Widget, Inc., currently trading for $100. The trader borrows $100 to buy the stock. The stock will pay a $2 dividend in 6 months and the trader will invest the proceeds for the remaining 6 months at a rate of 10%. Table 9.4 shows the trader's cash flows.
Table 9.4

Total Profit: P1 + $2.10 B $110.00
The trader's cash inflow after one year is the future value of the dividend, $2.10, plus the value of the stock in one year, P1, less the repayment of the loan, $110.
Chapter 9 21
Stock Index Futures Prices
From the above example, we can generalize to understand the total cash inflows from a cash-and-carry strategy.
1. The cash-and-carry strategy will return the future value of the stock, P1, at the horizon of the carrying period.
2. At the end of the carrying period, the cash-and-carry strategy will return the future value of the dividends.
– the dividend plus interest from the time of receipt to the horizon.
3. Against these inflows, the cash-and-carry trader must pay the financing cost for the stock purchase.
Chapter 9 22
Stock Index Futures Prices
In order to adjust the Cost-of-Carry Model for dividends, the future value of the dividends that will be received is computed at the time the futures contract expires. This amount is then subtracted from the cost of carrying the stocks forward.

Fair Value for Stock Index Futures
A stock index futures price has a fair value when the futures price conforms to the Cost-of-Carry Model.
In this section, we use a simplified example to determine the fair value of a stock index futures contract. Assume a futures contract on a price-weighted index, and that there are only two stocks. Table 9.5 provides the information needed to compute the stock index fair value.
Table 9.5
Information for Computing Fair Value Today's date: July 6 Futures expiration: September 20 Days until expiration: 76 Index: Price-weighted index of two stocks Index divisor: 1.80 Interest rates: All interest rates are 10 percent simple interest; 360 day

Notice that the fair value of the index (111.48) is different than the current level of the index (110.56). This difference suggests that possibility of an arbitrage.
Chapter 9 27
Index Arbitrage and Program Trading
Index arbitrages refer to cash-and-carry strategies in stock index futures. This section examines:
–Index arbitrage
–Program trading
Recall that deviations from the theoretical price of the Cost-of-Carry Model give rise to arbitrage opportunities.
If the futures price exceeds its fair value, traders will engage in cash-and-carry arbitrage.
A cash-and-carry arbitrage involves purchasing all the stocks in the index and selling the futures contract.
If the futures price falls below its fair value, traders can exploit the pricing discrepancy through a reverse cash-and-carry strategy.
A reserve cash-and-carry arbitrage involves selling the stocks in the index short and buying a futures contract.
We would expect the futures prices to follow those suggested by the Cost-of-Carry Model. To the extent that they do not, traders can engage in index arbitrage.
Chapter 9 28
Index Arbitrage
To demonstrate how index arbitrage works, we will examine a two-stock index. The Information on the index futures and the two stocks contained in the index are presented in Table 9.5.
Table 9.5
Information for Computing Fair Value Today's date: July 6 Futures expiration: September 20 Days until expiration: 76 Index: Price-weighted index of two stocks Index divisor: 1.80 Interest rates: All interest rates are 10 percent simple interest; 360 day

Chapter 9 29
Index Arbitrage
Using the previous calculations:
The cash market index value is 110.56.
Fair price for the futures contract is 111.48.
Rule #1
If the futures price exceeds the fair value, cash-and-carry arbitrage is possible.
Rule #2
If the futures price is below the fair value, reverse cash-and-carry arbitrage is possible.
Table 9.6 and 9.7 show the cash-and-carry and reserve cash-and-carry index arbitrage respectively.
Chapter 9 30
Index Arbitrage
Suppose the data from Table 9.5 holds, but the futures price is $115 which is above the fair value. The transactions for a cash-and-carry arbitrage are presented in Table 9.6.

August 12
Receive dividend of $1.00 from Stock B and invest for 39 days at 10%.
For illustrative purposes, assume any values for stock prices at expiration. We assume that stock prices did not change. Therefore, the index value is still 110.56. Receive proceeds from invested dividends of $1.52 and $1.01. Sell Stock A for $115 and Stock B for $84. Total proceeds are $201.53. Repay debt of $203.20.
At expiration, the futures price is set equal to the spot index value of 110.56. This gives a profit of 4.44 index units. In dollar terms, this is 4.44 index units times the index divisor of 1.8.

At expiration, the futures price is set equal to the spot index value of 110.56. This gives a profit of 5.56 index units. In dollar terms, this is 5.56 index units times the index divisor of 1.8.

Now suppose that all the information from Table 9.5 holds, but the futures price is $105, which is below the fair value of $111.48, so a reverse cash-and-carry arbitrage is possible.
Table 9.7 shows the transactions for a reverse cash-and-carry arbitrage.
Chapter 9 32
Program Trading
When performing index arbitrage, the investor must buy or sell all of the stocks in the index.
For example, to perform index arbitrage on the S&P 500 index, one would need to purchase or sell 500 different stocks.
Because of the difficulty in doing this, the trading is frequently done by computer. This is called program trading.
The computer will download the prices of all 500 stocks, compute the fair price of the index and compare that to the price of the futures contract.
If a cash-and-carry arbitrage is suggested, the computer will initiate trades to purchase all 500 stocks. It will also sell the futures contract.
Because of the number of stocks involved, performing a successful index arbitrage involves very large sums of money and very rapid trading. As such, institutional investors (mutual funds and the like) are the ones that typically engage in index arbitrage.
Chapter 9 33
Predicting Dividends Payments and Investment Rates
Dividend Amount and Timing
So far we have assumed certainty with regard to dividend amount, timing and investment rates.
In the real market, dividends are predictable, but are not certain.
To the extent that they are not predicted with certainty, the cash-and-carry index arbitrage can be frustrated.
For the DJIA with 30 stocks, dividends are relatively stable. Thus prediction can be moderately accurate.
For the SEP 500 or NYSE Indexes, many smaller companies are involved and dividend prediction becomes much less certain.
Moreover, dividends are paid in seasonal patterns as shown in Figure 9.2.
Predicting the Investment Rate
Predicting the investment rate for dividends can be done with some certainty, as it is a relatively short term investment that will occur in the near future.
Chapter 9 34
Distribution of Dividend Payments

Chapter 9 35
Market Imperfections and Stock Index Futures Prices
Recall that four market imperfections could affect the pricing of futures contracts:
1. Direct Transaction Costs
2. Unequal Borrowing and Lending Rates
3. Margins
4. Restrictions on Short Selling
Market imperfections exist and can be substantial, particularly for indexes with large numbers of stocks.
The existence of market imperfections leads to no-arbitrage bounds on index arbitrage.
So the price has to get out of sync by a good bit to cover the transaction costs and other market imperfections associated with attempting the arbitrage.
Chapter 9 36
Speculating with Stock Index Futures
Futures contracts allow speculators to make the most straightforward speculation on the direction of the market or to enter very sophisticated spread transactions to tailor the futures position to more precise opinions about the direction of stock prices.
The low transaction costs in the futures market make the speculation much easier to undertake than similar speculation in the stock market itself.
Tables 9.8 and 9.9 illustrate two cases of stock index futures speculation, a conservative inter-commodity spread and a conservative intra-commodity spread.

A trader observe that the DJIA futures is 8603.50 and the S&P 500 futures is 999. The trader expects the DJIA to go up more rapidly than the S&P 500 index due to market conditions. To bet on her intuition the trader enters into an inter-commodity spread as indicated in Table 9.8.
The spread has widened as expected and thus, the trader was able to realize a $16,447.50 profit.

In the event that a trader expects more distant contracts to be more sensitive to a market move than the nearby contracts. The trader initiates a intra-commodity spread as shown in Table 9.9.
In this case, the position is so conservative that there was little difference in the price changes, producing only a $112.50 profit, despite the fact that the market moved in the predicted direction.

Single Stock Futures
Single stock futures are priced using the Cost-of-Carry Model.
Example
Today, Feb 20, the current price of Wal-Mart stock is $59.45/share. The JUN futures contract for Wal-Mart will expires on June 18. Wal-Mart’s quarterly dividend is expected to be 9 cents/share on April 7. The current financing cost is assumed to be 1.6% per year.
Since there is only a single dividend payment during the life of the futures contract, the cost-of-carry relationship becomes simple:
F0,t = 59.45 *(1 + .016*119/365) - .09(1 + .016*72/119)
F0,t = $59.45 + .31 - .09
F0,t = $59.67/ share.

Risk Management with Security Futures Contracts: Short Hedging
Hedging with stock index futures applies directly to the management of stock portfolios. This section examines short and long hedging applications for stock index futures.
Assume that a portfolio manager has a well-diversified portfolio with the following characteristics:
Portfolio Value = $40,000,000
Portfolio Beta = 1.22 (relative to the S&P 500)
S&P 500 Index = 1060.00
The portfolio manager fears that a bear market is imminent and wishes to hedge his portfolio's value against that possibility.
The manager could use the S&P 500 stock index futures contract. By selling futures, the manager should be able to offset the effect of the bear market on the portfolio by generating gains in the futures market.

Risk Management with Security Futures Contracts: Short Hedging
Assuming that the S&P index futures contract stands at 1060, the advocated futures position would be given by:

where:VP = value of the portfolioVF = value of the futures contract
This strategy ignores the higher volatility of the stock portfolio relative to the S&P 500 index.

Sell 150 S&P 500 December futures contracts at 1060.00.
August 16 Stock portfolio falls by 5.40% to $37,838,160.
S&P futures contract falls by 4.43% to 1013.00.
Loss: B$2,161,840
Gain: 47 basis points $250 150 contracts = $1,762,500
Net Loss: B$399,340
The manager might be able to avoid this negative result by weighting the hedge ratio by the beta of the stock portfolio.
The failure to consider the difference in volatility between the stock portfolio and index futures contract leads to suboptimal hedging results.

Risk Management with Security Futures Contracts: Long Hedging
A pension fund manager is convinced an extended bull market in Japanese equities is about to begin. The current exchange rate is $1 per ¥140. The manager anticipates funds for investing to be ¥6 billion ( $42,857,143 ≈ $43,000,000) in 3 months. The pension fund manager trades as shown in Table 9.11.

A pension fund manager anticipates having -6 billion to invest in Japanese equities in three months.
Buys 600 SEP Nikkei futures on the CME at 14,400.
August 15
-6 billion becomes available for investment.
The market has risen and the Nikkei futures stands at 14,760.
Stock prices have risen, so the -6 billion will not buy the same shares that it would have on May 19.
Futures profit: 360 points $5 600 contracts = $1,080,000
The futures profit offsets the additional cost of purchasing stocks because of an increase in prices.
