4 terms

open-market sale financial

"transaction_action: "open-market sale""

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.

weighted average financial

"Represents the weighted average of a range of sale prices"

A weighted average is a way of calculating an overall number when some items matter more than others by giving each item a different level of importance, or weight. Investors use weighted averages to combine figures like prices, returns or earnings so the result reflects the size or significance of each part — like grading a class where a final exam counts more than a quiz, producing a score that better represents true performance.

Common Shares financial

"security_title: "Common Shares""

Common shares are the basic units of ownership in a company that give holders a claim on profits and a right to vote on key matters, like electing the board. Think of them as membership cards in a club: they let you share in successes and losses, but in a bankruptcy or liquidation they are paid after creditors and preferred shareholders, so their value can swing more and matters for assessing risk and potential return.

transaction code "S" financial
