Definition:
A Stock represents a share of ownership in a company. When you purchase stock, you own a fraction of that company, entitling you to a portion of its assets, earnings, and in some cases, voting rights. Stocks are a primary way for companies to raise capital and for investors to build wealth through capital appreciation and dividends.
Types of Stocks:
| Type | Description |
|---|---|
| Common Stock | Offers voting rights and potential dividends; most widely traded form |
| Preferred Stock | Usually no voting rights; has fixed dividends and priority in liquidation |
| Class A / B Shares | Different voting power or dividend rights based on share class |
| Growth Stock | Expected to grow faster than the market; usually reinvests earnings |
| Value Stock | Trades below its intrinsic value; often pays dividends |
| Dividend Stock | Regularly pays a portion of earnings to shareholders |
How Stocks Work:
- Companies issue stock via Initial Public Offerings (IPOs) or secondary offerings
- Stocks are traded on public exchanges like the NYSE, Nasdaq, LSE, or Borsa Istanbul
- Stock prices fluctuate based on supply and demand, company performance, and market sentiment
- Investors can earn money through:
- Capital Gains (buying low and selling high)
- Dividends (regular income from company profits)
Stock Example:
If you own 100 shares of a company with 1,000,000 total shares outstanding, you own 0.01% of the company.
If the company declares a $1 dividend per share, you’d receive $100 in total dividends.
