The Forward Equation is a mathematical expression used in various fields, including finance and physics, to describe how a quantity changes over time. It often represents the relationship between the current value of a variable and its future value, taking into account factors like interest rates or market conditions. This equation is essential for modeling scenarios where predictions about future states are needed. In finance, the Forward Equation is particularly important for pricing derivatives, such as options. It helps traders and analysts understand how the value of an asset, like a stock or commodity, will evolve, allowing them to make informed decisions. The equation is closely related to concepts like Black-Scholes Model and risk management.
