VWAP trades should be reported how soon after close of trading?

• A. Immediately
• B. 30 minutes after close
• C. 1 hour after close
• D. Next trading day morning

Answer: (B)

VWAP trades are reported within a short window after the market closes to finalize and share the day’s execution data in a timely way. This timing keeps the end-of-day VWAP calculation accurate by including trades from the entire session, including those completed near the close, while still allowing a brief period for trade matching, validation, and dissemination. Reporting immediately wouldn’t capture late-session trades, which can skew the day’s VWAP. Waiting an hour or more would delay the data too much, reducing its usefulness for benchmarking and reconciliation. Waiting until the next trading day morning would be too late for daily performance comparisons and end-of-day reporting. So, 30 minutes after close strikes the right balance between timeliness and accuracy.
