Trading Case B03

 

 

Case Objective

To understand the cash flows from forward contracts on bonds; to determine forward prices on bonds.

 

Key Concepts

Forward contract; time value of money; discounting; bond prices and interest rates.

 

Case description

There are 4 bonds and two forward contracts. This trading exercise covers three years of calendar time.  However, you will only trade the first day of each year.  That is, day 1 opens for trading first.  At the end of day 1 time flashes by and year end settlements then take place.  Shortly after this day 1 for year 2 opens for trading.  Again at the end of day 1, year 2 time flashes by and end of year 2 settlements take place.   Finally, day 1 year 3 opens for trading.  At the end of day 1 year 3 time flashes by and end of year 3 settlements take place which now converts your entire position to cash.

 

Each bond has a face value of 100.  The cash flow from each bond at the end of each year is shown below. The first forward contract is on the zero coupon bond that matures in year 2, and the forward contract matures at the end of year 1.  The second forward contract is on the zero coupon bond that matures at the end of year 3, and the forward contract itself matures at the end of year 2.

 

The interest rate is initially 4%  In year 2, it is 10%, while in year 3, it is 16%.  You earn interest on cash at these rates. and so on.  You can also borrow at these rates in each year.

 

You can short sell bonds and forward contracts.  If you short  sell a bond and donít cover your position, then you will have to pay any coupons and/or face value on that bond at the end of the year.  If you short sell a forward, you will have to deliver the underlying bond when the forward matures.  Note that when you trade a forward contract, no money changes hands.

 

Prices in this case are determined by the traders, so all trades will take place at bids and asks that either you or another trader in the system puts in.  The price you bid/ask for a forward contract is the forward price.

Money Market Time Line

 

In the money market c0 is your initial endowment of market cash, and c1 is your closing balance of market cash after all of the first year's trading activities are accounted for. C1 can be positive or negative (if you have borrowed market cash).  C1b is the total cash received from any bonds you own less (plus) the cost (revenue) from any forward contracts you purchased (sold) during year 1.  The one plus risk-free rate of interest (4%) is denoted by (1.04).

Years 2 and 3 are interpreted in an equivalent manner.  In year 2 the one plus risk-free rate is (1.10) and in year 3 this rate is (1.16).

 

Earning Grade Cash

Your aim is to make as much money as you can which depends upon how well you trade relative to the prices discovered by the market.   Each trial you earn grade cash that is cumulated across trials.  Grade case in any trial equals 0.0001 x your closing balance of market cash.  That is, if you end up with negative wealth then you lose grade cash and if you make money then you gain grade cash.

 

Trading is conducted over a number of independent trials and a record of your cumulative grade cash is maintained.
