Implementation Shortfall

Implementation shortfall refers to the difference between the actual performance of a trade and the expected performance if it had been executed perfectly. It measures the cost of trading inefficiencies, including delays, price slippage, commissions, and market impact. The goal of minimizing implementation shortfall is to reduce the gap between the intended and actual results of a trade, ensuring that trading costs and execution risks are minimized.

Example

An investor plans to buy 1,000 shares of a stock at $50 per share, but due to delays and market fluctuations, the final purchase price averages $52 per share. The $2 per share difference represents the implementation shortfall.
