open-market sale financial
"transaction_action: open-market sale with a transaction_code S for common stock."
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.
derivative exercise/conversion financial
"transaction_action: derivative exercise/conversion for non-derivative and derivative option records."
