Understanding Market Capitalization
Market capitalization, often called "market cap," is the total value of a company’s outstanding shares of stock in the US stock markets. It is calculated by multiplying the current share price by the total number of outstanding shares. Market cap helps investors gauge a company’s size, risk, and investment potential, categorizing companies as large-cap, mid-cap, or small-cap, each with distinct characteristics and risk profiles in the market.
