What Is It?
Stocks (equities or shares) represent ownership in corporations. Stockholders participate in profits through dividends and capital appreciation. Stocks are the primary growth vehicle in most investment portfolios and the focus of public equity markets.
Origin
Equity ownership dates to medieval trade partnerships. Modern stock exchanges emerged in Amsterdam (1602) and London (1698). The New York Stock Exchange (1792) became the world's largest. Index funds (1970s) and ETFs (1990s) democratized access.
Why It Matters
Stocks provide long-term growth potential exceeding other asset classes. They represent claims on economic productivity and innovation. Stock markets allocate capital to enterprises and enable wealth creation. Equity risk premium compensates for volatility.

Market Mechanics
Stocks trade on exchanges and OTC. Price reflects supply/demand and fundamental expectations. Common stock has voting rights; preferred has priority dividends. Indices (S&P 500, MSCI) benchmark performance. Market cap segments: large, mid, small.
How It Behaves
Stocks are volatile and cyclical but trend upward over time. Earnings drive long-term returns; multiples drive short-term fluctuations. Sectors rotate through cycles. International diversification reduces country-specific risk. Beta measures market sensitivity.
