Introduction to Financial Markets for Beginning Investors

This chapter introduces the market structure behind investing. Before selecting securities or building strategies, investors need a working understanding of where securities trade, how new issues become tradable assets, how exchanges differ from dealer markets, and how benchmarks help interpret performance.

The chapter also explains the roles of the major market participants and the basic price logic that governs securities trading. Together, these topics help a new investor read market activity more clearly and avoid treating price movement as random noise.
