Market Impact Cost

Market impact cost is the cost associated with the price change of a security due to the execution of a large trade. When a large order is placed, the increased buying or selling pressure can cause the price to move against the trader, resulting in higher costs. Market impact costs are particularly important for institutional investors and hedge funds that deal with significant volumes of trades, as these costs can reduce overall returns.

Example

A hedge fund places a large buy order for a stock, causing its price to rise. The higher price the fund pays for the stock is the market impact cost.
