Key Terms

volume-weighted average price, market abuse regulation, disclosure guidance and transparency rules

3 terms

volume-weighted average price financial

"purchased 328,781 shares of common stock... at a volume-weighted average price of $13.402"

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.

market abuse regulation regulatory

"In accordance with Article 5(1)(b) of Regulation (EU) No 596/2014 (the Market Abuse Regulation)"

Market abuse regulation consists of laws and rules designed to prevent dishonest or manipulative practices in financial markets. It aims to ensure fair and transparent trading, so investors can trust that markets operate honestly, much like rules that keep a game fair. By reducing unfair advantages, it helps protect investor confidence and promotes healthy, efficient markets.

disclosure guidance and transparency rules regulatory

"determine if they are required to notify their interest... under the FCA's Disclosure Guidance and Transparency Rules"

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.
