📈 What is a Stock?
A stock represents ownership in a company. When you buy a stock, you’re purchasing a small piece of that company and becoming a shareholder. As the company grows and profits, your stock may increase in value. Companies issue stocks to raise capital for expansion, research, or other business needs.
Key Benefits of Stock Ownership
- Capital Appreciation: Potential for stock price to increase over time
- Dividend Income: Regular payments from profitable companies
- Voting Rights: Influence on major company decisions
- Liquidity: Easy to buy and sell during market hours
- Inflation Hedge: Stocks historically outpace inflation long-term
