Key Terms

volume-weighted average price financial

"purchased 36,320 shares ... at a volume-weighted average price of $13.9528"

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.

par value financial

"shares of common stock, par value $0.01 per share of the Company"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.

trading venue technical

"Trading venue | Currency NYSE | USD | $13.9528 | | 36,320"

A trading venue is any organized place or system where buyers and sellers meet to swap stocks, bonds or other securities, like a physical market or an online exchange. It matters to investors because the venue determines how easily orders are filled, how quickly prices move, what rules and fees apply, and how transparent pricing is — much like choosing a busy bazaar versus a small shop affects price, speed and cost.

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

"to notify their interest in ... 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.
