Key Terms

public offering, dual listing, indirect ownership, Rule 10b5-1

4 terms

public offering financial

"Participation in the public offering undertaken by Star Bulk Carriers Corp in Greece"

A public offering is when a company sells shares to the general public through the stock market, either by issuing new shares to raise cash or by letting existing owners sell their stakes. Think of it like a business opening its doors to many new owners at once: it can bring in money for growth but also increases the number of shares available, which can change the stock price and dilute existing ownership — key factors investors watch closely.

dual listing financial

"following its dual listing on Euronext Athens"

A dual listing is when a company makes the same shares available on two different stock exchanges, often in different countries, so investors can buy and sell the same ownership stake in more than one market—like a shop opening branches in two cities that sell the same product. It matters to investors because it can widen the pool of buyers, make shares easier to trade, expose the stock to different currencies and rules, and create price differences or arbitrage opportunities that affect returns and risk.

indirect ownership financial

"These shares are held by 3 corporations in which the reporting person holds 100%"

Rule 10b5-1 regulatory

"No Rule 10b5-1 trading plan is reported for the transactions"

Rule 10b5-1 is a regulation that allows company insiders to buy or sell their shares at predetermined times, even if they have access to non-public information. It acts like setting a schedule in advance for transactions, helping prevent accusations of unfair trading. This rule provides a way for insiders to plan trades transparently, giving investors confidence that these transactions are not based on hidden information.
