Most transactions today occur electronically, connecting remote participants. This article dives deeper into the stock market's functions, components, and significance within the global economy.

What is the Stock Market?

The stock market can be understood as the collective trading network involving company shares and their derivatives. It is a central pillar of modern economies, providing companies with a vital source of capital required for expansion, research and development, debt consolidation, and more.
