Aggregate Market Value financial

"Aggregate Market Value"

Aggregate market value is the combined price you would pay to buy all outstanding shares of a company or all companies in a group at current market prices — essentially the sum of each stock’s market capitalization. It matters to investors because it shows the overall size and weight of an investment or sector (like the total cost to buy every piece of a puzzle), helps compare scale across companies or markets, and influences index composition and risk exposure.

Approximate Date of Sale financial

"Approximate Date of Sale"

Stock Grant financial

"Nature of Acquisition Transaction: STOCK GRANT"

A stock grant is an award of company shares given to an individual, often as part of compensation for employees or executives. It matters to investors because grants can change the number of shares outstanding (dilution) and signal how company leaders are being paid and motivated—think of it like receiving a slice of the company as part of your paycheck, which can affect ownership and future share supply.
