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.

volume weighted average price financial

"The price reported in Column 4 is a volume weighted average price."

The volume weighted average price (VWAP) is a way to measure the average price of a security, such as a stock, over a specific period, taking into account how many units were traded at each price. It’s similar to calculating the average cost of items bought when some are more frequently purchased than others. Investors use VWAP to assess whether a security is being bought or sold at a fair price during trading.
