Key Concepts

Antithetic Variable Method

The antithetic variable method is a specific variance reduction strategy in which pairs of negatively correlated sample paths are generated. By simulating each path together with its antithetic counterpart (often by inverting the random inputs), the variability in the payoff estimates tends to cancel out, leading to a more stable and precise overall estimate of the option's price.

Variance Reduction Techniques

Variance reduction techniques are methods applied in Monte Carlo simulation to decrease the statistical error of the estimated results, providing more accurate and reliable estimates with fewer simulation runs. These techniques strive to reduce the variability inherent in the random sampling process, thereby improving the efficiency and precision of the simulation outcomes.

Monte Carlo Simulation

Monte Carlo simulation is a computational method used to model and estimate the behavior of complex systems by generating a large number of random samples. In the context of option pricing, it involves simulating many potential future paths of the underlying asset price to estimate the expected payoff of an option, providing a numerical solution when analytical methods are difficult or unavailable.

European Option Pricing

European option pricing involves determining the fair value of an option that can only be exercised at its expiration date. The pricing requires calculating the expected payoff under the risk-neutral measure and discounting it back to present value. Monte Carlo simulation is often used in this context to simulate the underlying asset’s paths and compute the average payoff accurately over numerous simulated scenarios.
