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.

employee stock options financial

"Exercise of employee stock options"

Employee stock options are contracts that give workers the right to buy a company's shares at a set price sometime in the future, like a coupon that lets you purchase stock at today’s price later on. Investors care because they align employees’ incentives with company performance and create a potential future claim on shares that can reduce existing owners’ percentage and add to a company’s reported compensation costs.
