Continuous dividend v discrete cash flows
Variation margin With the generalization of variation margin collateral, the derivative world is not driven anymore by discrete cash flows but continuous dividend. This can be explained with the following two graphs. Figure 1: Derivative value Suppose that you have entered into a derivative in the past. In the graphs that date was 20 days ago and the X axis represent the time. You entered into the trade at fair price, so the initial value was 0. Time has past and the value has gone up and down. The Y axis of the same graph is the value. The current value is positive. As the party to the trade are uncertain that their counterpart will honor its derivative obligations, it is now standard to ask for variation margin related to the derivative. In this context variation margin is the exchange on a daily basis of collateral to guarantee the obligation. The party out-of-the-money (for which the value is negative) is posting financial instrument with the same value as the trade as a g...
