3 terms

Rule 10b5-1 trading plan regulatory

"No Rule 10b5-1 trading plan is reported for this transaction"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

open-market transaction financial

"purchase in an open-market transaction at a weighted average price"

An open-market transaction is a buy or sell of a company's shares or other securities conducted on a public exchange at the current market price, rather than through a private agreement. Investors watch these trades because they change the number of shares available and can move the price immediately—similar to how a large purchase at a busy store can raise demand and affect the checkout price—so such activity can signal market sentiment and alter ownership stakes.

weighted average price financial

"open-market transaction at a weighted average price of $49.68 per share"

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
