Key Insights
- Stock markets are where buyers and sellers trade ownership shares in public companies.
- This module explains exchanges, order types, market participants, bid-ask spreads, and how prices are determined.
Overview
Stock markets are organized venues where buyers and sellers trade shares of publicly listed companies. They provide liquidity, price discovery, and access to capital for businesses while offering investors opportunities to own portions of companies and participate in economic growth. Understanding how stock markets operate is fundamental to participating in modern financial systems.
Stock exchanges like the NYSE and NASDAQ serve as the primary trading venues, with market participants including individual investors, institutional investors, market makers, and high-frequency trading firms. Orders are matched through electronic order books that display bid and ask prices, with trades executed when orders cross. Market movements are driven by a complex interplay of company performance, economic conditions, and investor sentiment.
Key Concepts
- Bid-Ask Spread: The difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller will accept (ask).
- Market Order: An order to buy or sell at the current best available price, guaranteeing execution but not price certainty.
- Limit Order: An order to buy or sell at a specified price or better, guaranteeing price but not execution.
- Liquidity: The ability to buy or sell an asset quickly without causing a significant price movement.
- Market Capitalization: The total market value of a company's outstanding shares, calculated as share price times shares outstanding.
Key Takeaways
- Stock markets provide liquidity, price discovery, and capital access for businesses and investors.
- Exchanges match buyers and sellers through electronic order books with bid and ask prices.
- Market orders prioritize execution speed; limit orders prioritize price certainty.
- Liquidity is essential for efficient market functioning and fair price discovery.
