The volume weighted average price (VWAP) is a way to measure the average price of a security, such as a stock, over a specific period, taking into account how many units were traded at each price. It’s similar to calculating the average cost of items bought when some are more frequently purchased than others. Investors use VWAP to assess whether a security is being bought or sold at a fair price during trading.
