vesting financial
"The option vests as to 1/12 of the underlying shares monthly"
Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
expiration date financial
"expiration_date: "2036-06-01T00:00:00.000Z""
The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised. It matters to investors because it determines the timeframe during which they can take action or benefit from the contract, similar to how a coupon or a food item has a limited period of usefulness. Once the expiration date passes, the contract loses its value or ability to be used.
derivative financial
"transaction_type: "derivative""
A derivative is a financial contract whose value depends on the price or performance of another asset or measure — for example a stock, index, interest rate, commodity, or currency. Investors use derivatives like insurance or leveraged bets to hedge risk, speculate, or gain exposure without owning the underlying asset; they can protect portfolios but also amplify losses and introduce counterparty and market risk.
