For many contracts physical delivery is not possible or inconvenient and cash settlement applies. Here an equivalent cash payment between the parties is initiated. A futures contract can be bought and sold at any time point until its delivery date. The corresponding price is the futures price. At each trading day a settlement price is quoted, usually the closing price immediately before the end of trading day. The settlement price is used to determine the margins that are required from any investor.

However, the test should be 28 ELEMENTARY FINANCIAL CALCULUS used only for large data sets. Notice that the Jarque and Bera test measures the departure of the sample skewness and kurtosis from their theoretical values under the null hypothesis. Another class of tests is based on the following idea. If the null hypothesis is true, we estimate the parameters μ and σ 2 by their sample analogs μT and ST2 . The corresponding estimate of the distribution function is then (μT ,S 2 ) (x). e. FT (x) = 1 T T 1(Rt ≤ x), x ∈ R, t=1 which provides a consistent estimator of F (x) without assuming any specific shape of the distribution.

Axiom (i) requires that the risk of a position increases, if the random payment profile increases for all states ω ∈ . The second axiom addresses an important aspect of risk management: Risks associated to two positions may cancel when aggregating them. The standard √ deviation σ(X) = Var (X) satisfies axiom (ii) and (iii). To see (ii), use the inequality Cov(X, Y ) ≤ σ(X)σ(Y ) to obtain σ(X + Y ) = 2 ≤2 X Y + 2 2 Var 1 2 2 1 2 2 + σX σX σY + 2 2 = σX + σY =2 2 σY2 + σX σY 2 for any pair (X, Y ) of random variables with existing second moments and arbitrary correlation.
