Understanding the Law of One Price: A Legal Perspective

Definition & Meaning

This means that if a particular security can be replicated using a combination of other securities, the price of the original security and the combined price of the replicating securities must be equal. This concept is crucial for understanding how markets operate and ensures fair pricing across different trading platforms.
