An investor enters into a long position in NN futures contracts on an index, where each contract has a notional value of VV times the futures price F0F0. The initial margin is 20% of the notional value for NN contracts. There is no maintenance margin requirement. The margin account earns a continuously compounded interest rate of 10%. The futures contracts are marked-to-market weekly. Assume there are 52 weeks in a year. One week later, the futures price decreases by 15%. Calculate the percent change in the investor's margin account after one week.

M. cotteleer electronics supplies microcomputer circuitry to a company that incorporates microprocessors into refrigerators and other home appliances. one of the components has an annual demand of 235 units, and this is constant throughout the year. carrying cost is estimated to be $1.25 per unit per year, and the ordering (setup) cost is $21 per order. a) to minimize cost, how many units should be ordered each time an order is placed? b) how many orders per year are needed with the optimal policy? c) what is the average inventory if costs are minimized? d) suppose that the ordering cost is not $21, and cotteleer has been ordering 125 units each time an order is placed. for this order policy (of q = 125) to be optimal, determine what the ordering cost would have to be.
