The US stock market is one of the largest and most influential in the world. Whether you're a seasoned investor or just starting out, understanding how it works is crucial. This article delves into the core mechanisms, terms, and strategies that drive the US stock market, providing a comprehensive guide for investors.
Understanding the Basics
The stock market is essentially a place where buyers and sellers come together to trade shares of publicly-traded companies. Here's a breakdown of the key components:
Stocks and Shares: A stock represents ownership in a company, and shares are individual units of that ownership. When you buy a stock, you're essentially buying a piece of that company.

Long-term Investing: Holding stocks for the long term and benefiting from the potential growth in the company's value.
Short-term Trading: Buying and selling stocks within a short time frame, often based on technical analysis.
Dividend Investing: Focusing on stocks that offer regular dividend payments.
