Understanding Implementation Shortfall: The Key to Evaluating Trading Performance

When analyzing implementation shortfall, what is important for comparing performance?

• A. The execution price of the shares
• B. The decision price set before order execution
• C. The price of shares when the order is cancelled
• D. The average trading volume on that day

This helps identify inefficiencies and potential areas for improvement in future trading activities. While the execution price and other elements like trading volume may provide context, they do not serve as the benchmark for assessing the performance impact of implementation shortfall as directly as the decision price does.
