Rule 10b5-1 trading plan regulatory

"Sale of stock reported on this Form 4 was affected pusuant to a 10b5-1 trading plan"

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.

weighted average purchase price financial

"The price reported above reflects the weighted average purchase price."

The weighted average purchase price is the average cost per share you paid across multiple buys, calculated so larger purchases count more than smaller ones. Imagine buying apples at different prices: the overall price you effectively paid depends on how many apples you bought at each price. Investors use it to measure true cost basis, calculate gains or losses, decide when to sell, and manage taxes and portfolio performance.

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.

Common Stock financial

"security_title": "Common Stock""

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.
