Answer:
<em>Arbitrage </em>
Explanation:
Arbitrage is <em>buying and selling an asset concurrently to benefit from a market imbalance.</em>
It is a transaction that gains on various markets or in various forms by leveraging the price differences of identical or similar financial products.
Because of market distortions, arbitration exists and therefore would not happen if all markets were completely effective.
