As traders exploit this arbitrage opportunity, the futures price will fall. Suppose next that the futures price is below the spot price during the delivery period. Companies interested in acquiring the asset will ﬁnd it attractive to enter into a long futures contract and then wait for delivery to be made. As they do so, the futures price will tend to rise. The result is that the futures price is very close to the spot price during the delivery period. 1 illustrates the convergence of the futures price to the spot price.

When the delivery period is reached, the futures price equals——or is very close to—the spot price. To see why this is so, we ﬁrst suppose that the futures price is above the spot price during the delivery period. Traders then have a clear arbitrage opportunity: 1. , short) a futures contract 2. Buy the asset 3. Make delivery. These steps are certain to lead to a proﬁt equal to the amount by which the futures price exceeds the spot price. As traders exploit this arbitrage opportunity, the futures price will fall.

Mechanics of Futures Markets Z9 margin call from the broker for an additional \$4,020 to bring the account balance up to the initial margin level of \$12,000. It is assumed that the investor provides this margin by the close of trading on Day 8. On Day 11, the balance in the margin account again falls below the maintenance margin level, and a margin call for \$3,780 is sent out. The investor provides this margin by the close of trading on Day 12. On Day 16, the investor decides to close out the position by selling two contracts.
