Few theories about derivatives

Stochastic Process

Any variable whose value changes over time in an uncertain way is said to follow a stochastic process. Stochastic processes can be classified as discrete time or continuous time.

A discrete-time stochastic process is one where the value of the variable can change only at certain fixed points in tme, whereas a continuous-time stochastic process is one where changes can take place at any time.

Stochastic processes can also be classified as continuous variable or discdrete variable.

Exotic Option

Derivatives with more complicated payoffs than the standard European or American calls and puts are sometimes referred to as exotic options.

Most exotic options trade in the over-the-counter market and are designed by financial institutions to meet the requirements of their clients.
