Market capitalization is the total market value of a company's outstanding shares of stock, calculated by multiplying the stock price by the number of shares outstanding. It represents the market's current consensus on what the entire company is worth and is the starting point for nearly all valuation analysis.
Market cap is used to categorize companies by size: mega-cap (above $200B), large-cap ($10B-$200B), mid-cap ($2B-$10B), small-cap ($300M-$2B), and micro-cap (below $300M). These size categories affect which funds can invest in a stock, how liquid the shares are, and what benchmark the company is measured against.
Market Capitalization = Stock Price × Basic Shares Outstanding
GeminIQ multiplies the closing stock price on the filing period end date by the period-end basic shares outstanding from the SEC filing. This ensures market cap is calculated on the same share count basis used for all per-share metrics, maintaining internal consistency. The stock price is sourced from market data for the trading day closest to the filing period end date.
A: Using period-end basic shares (rather than diluted shares or a different date's count) ensures that market cap is on the same basis as EPS, cash flow per share, and all other per-share metrics on GeminIQ. This prevents apples-to-oranges comparisons when using market cap in ratio calculations like P/E, P/B, and P/S.
A: No. Market cap values only the equity portion of the company. Enterprise value adds net debt (total debt minus cash) to market cap, representing the total cost to acquire the entire business including assuming its debt and gaining access to its cash.
A: Differences arise from the stock price date used and the share count source. Some platforms use real-time prices, others use period-end prices. Share counts can differ depending on whether the platform uses basic vs. diluted shares and whether it uses the SEC-reported count or a more recent estimate. GeminIQ uses the period-end price and basic shares from the filing.
