How Does the Stock Market Work?
Quick answer: Stock exchanges and brokers help buyers and sellers trade ownership interests, with market rules governing how orders are handled.
Understand the core concept
Companies can raise capital through issuing shares. Later, those shares may trade between investors on secondary markets; those secondary transactions generally do not send sale proceeds back to the issuer.
See how it works
A broker receives investor orders, while exchanges and other trading venues facilitate transactions under specific rules. Bid and ask prices can differ, creating a spread.
Know the limitations
A market order emphasizes execution but its price is uncertain. A limit order sets a price boundary yet may not execute. Liquidity and volatility affect outcomes.
Put it into context
Prices can move after earnings releases, economic reports, shifts in interest-rate expectations or changes in investor sentiment. There is no single cause behind every move.

Sketch the path from investor to broker to trading venue, then explain the difference between a bid and ask.
