Key Terms

volume-weighted average price financial

"the market at a volume-weighted average price of $13.8798 per Share"

Volume-weighted average price (VWAP) is the average price of a stock over a specific time period where each trade is weighted by the number of shares traded, so larger trades influence the average more than small ones. Investors and traders use VWAP as a reference point to judge whether trades are happening at relatively good or poor prices—like checking the average price paid for an item at a market where bulk purchases count more than single-item buys.

Disclosure guidance and transparency rules are the standards and regulations that require companies to share clear, timely information about their finances, risks, operations and material events. They matter to investors because consistent, honest reporting is like a car’s dashboard — it reveals the data you need to judge safety and performance and make informed buying or selling decisions. Strong disclosure reduces surprises and helps keep markets fair and efficient.
