Key Terms

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

4 terms

volume-weighted average price technical

"in the market at a volume-weighted average price of $13.7436 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.

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.

isin technical

"Shares purchased: | DIVERSIFIED ENERGY COMPANY (ISIN: US25520W1071)"

A 12-character International Securities Identification Number (ISIN) is a unique code that acts like a passport for a specific stock, bond or other tradable security so it can be identified worldwide. Investors and systems use it to ensure they are buying, selling and tracking the exact same instrument across exchanges and data feeds, which prevents costly mix-ups and makes portfolio reporting, settlement and regulatory checks simpler and more reliable.

View in glossary

disclosure guidance and transparency rules regulatory

"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.
