Large cap, mid cap & small cap
Companies are grouped by market capitalization into tiers — mega, large, mid, small, and micro cap — that broadly signal size, stability, and risk.
Market-cap tiers sort companies by their total equity value. The common bands are mega cap (roughly $200 billion and up), large cap (about $10 billion to $200 billion), mid cap (about $2 billion to $10 billion), small cap (about $300 million to $2 billion), and micro cap (below that). The exact cutoffs vary between providers, so treat them as rough zones rather than fixed lines.
Size tends to correlate with risk and growth potential. Large and mega caps are usually more established, stable, and widely followed, but grow more slowly; small caps can grow faster and are less picked-over by analysts, but are more volatile and more exposed to the domestic economy. Many investors hold a mix across tiers.
stocks-llm lets you filter the catalog by these size bands, computed from the delayed daily-close price and shares outstanding. The tiers are context for comparing companies, not a signal in themselves.
