"144: Securities To Be Sold"

"Common Stock | 12/17/2023 | Vesting of Restricted Stock"

aggregate market value financial

"Common Stock | Deutsche Bank Securities Inc. ... | 100000 | 9358000"

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.
