What Is It?
Stocks are shares of ownership in a publicly traded company. When you buy a stock, you become a partial owner and can profit if the company grows through rising share prices or pays dividends. Stocks are the most common way everyday investors participate in the growth of businesses.
Origin
The modern stock market began in 1602 with the Dutch East India Company, the first company to issue shares to the public. The New York Stock Exchange was founded in 1792 under a buttonwood tree on Wall Street. By the 20th century, stocks became the cornerstone of wealth creation for individuals and institutions.
Why It Matters
Stocks are the primary engine of capital formation for companies and the main vehicle for long-term wealth building. They represent real ownership in the economy and have historically delivered the highest returns of any major asset class over decades.

Stocks exhibit volatility but tend to trend upward over long periods. They react to company-specific news, sector trends, macro events, earnings growth, interest rates, and liquidity conditions.
