Common Stock financial
"security_title: "Common Stock""
Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.
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.
