ARBITRAGE
Back to GlossaryDefinition
Simultaneous buying and selling of the same or equivalent asset to profit from price differences across markets.
Summary
Arbitrage is a risk-free trading strategy where investors simultaneously buy and sell identical or equivalent assets in different markets to capture price differences. Think of it like buying a book for $10 on one website and immediately selling it for $12 on another website - you pocket the $2 difference with no risk. In financial markets, arbitrageurs act as market efficiency enhancers by eliminating price discrepancies across different exchanges or markets.
Usage Context
Understanding arbitrage is crucial when studying market efficiency, pricing models, international finance, derivatives, and how financial markets eliminate price discrepancies to maintain equilibrium.
Common Confusions
