Conservative investors take profits when they have made 50% selling a call or put. Others exit at 70% or higher. The percentage doesn't matter.
An option payoff diagram is a graphical representation of the net Profit/Loss made by the option buyers and sellers. Before we begin with the explanation, it is important to note that the "Breakeven" point is the point at which you make no profit or no loss.
A payoff matrix is a type of prioritization matrix, which is a visual representation of the outcomes or payoffs of different choices made by individuals in a strategic scenario. It's a very simple 2×2 (or larger) grid in which you pit two or more possible strategie against each other and inspect every possible outcome.
The payoff function is a function u i : S 1 × S 2 × ⋯ S m → R .
The expected payoff is the average of the payoffs, weighted by the probabilities of each payoff, i.e., 0.4 200 + 0.6 500 = 380.
