Large Cap
Companies with a market capitalization generally above $10 billion. Large caps are the most liquid, most-analyzed tier of the stock market.
Large-cap stocks are the biggest companies by market capitalization. The threshold is not universally fixed, but $10 billion+ is the common definition; major indices like the S&P 500 are composed entirely of large caps.
Large caps offer deep liquidity — institutions can buy and sell hundreds of millions of dollars without moving the price significantly. They are covered by dozens of sell-side analysts, making information widely available and mispricings less common.
The size spectrum: mega-cap ($200B+), large-cap ($10B–$200B), mid-cap ($2B–$10B), small-cap ($300M–$2B), micro-cap ($50M–$300M), nano-cap (below $50M).
