Execution Cost Analysis Interview Guide
Execution cost analysis interview guide covering benchmarks, spread cost, market impact, delay, fees, attribution, and examples.
Candidates reviewing fills, benchmarks, spread, impact, and timing costs.
Execution cost analysis decomposes realized cost
Execution analysis separates spread, impact, delay, fees, taxes, opportunity cost, and benchmark drift so problems can be diagnosed.
Use the right benchmark
Arrival price, VWAP, close, midquote, or a custom benchmark can each answer a different question about execution quality.
Concrete example
A fill that beats VWAP can still be poor against arrival price if the order waited while the market moved away before trading.
Attribution guides improvement
Cost components can suggest smaller slices, different venues, higher urgency, lower participation, better forecasts, or different benchmark choice.
Common mistakes
Candidates often collapse everything into one slippage number. A useful review explains why the cost happened and what can change.
