What is VWAP?
Understanding Volume Weighted Average Price
Volume Weighted Average Price (VWAP) is a trading benchmark that represents the average price a security has traded at throughout the day, based on both volume and price. It provides traders with insight into both the trend and value of a security.
VWAP is calculated by adding the dollars traded for every transaction (price multiplied by the number of shares traded) and then dividing by the total shares traded.
VWAP Formula:
VWAP = Σ(Price × Volume) / Σ(Volume)

Why VWAP Matters
True Price Discovery
VWAP provides a more accurate representation of a stock's trading activity throughout the day, rather than just the closing price. This is crucial for understanding the true market sentiment and price discovery process.
Institutional Benchmark
Institutional traders use VWAP as a benchmark to evaluate their execution quality. Trading below VWAP when buying or above VWAP when selling is considered favorable execution.
Prevents Manipulation
By considering volume, VWAP helps identify when a stock's price might be artificially manipulated. End of day selling at lower prices has less impact on VWAP if volume is low, revealing the true trading pattern.
VWAP vs. Simple Average Price
Unlike a simple average price, VWAP gives more weight to prices at which more shares were traded. This provides a more accurate representation of the true trading activity and prevents misleading conclusions from low-volume price movements.
For example, if a stock trades at $10 for most of the day with high volume, but drops to $9.50 in the final minutes with minimal volume, the VWAP will remain closer to $10, reflecting the price at which most trading actually occurred.
