A stock is a small piece of a company. Buy 1 share of AAPL and you become a proportional owner of Apple. The company’s assets, debt, and earnings — your tiny slice includes them all.
Concrete example: AAPL has about 15.5 billion shares outstanding. Buy 1 share and you own 1/15,500,000,000 of Apple. No management role, but the ownership ratio is mathematical.
3 rights of a shareholder:
- Dividend (if declared).
- Voting at the annual meeting (1 share = 1 vote typically).
- Pre-emptive rights in rights offerings.
Stock price = the market’s current valuation estimate. Two people give different prices. The midpoint is the “current price.” Not the same as the company’s intrinsic value.
What moves stock price? Short-term: news, earnings beats/misses, Fed expectations. Long-term: earnings growth, sector dynamics. Weak company financials → falling price.
Common vs preferred stock:
- Common: standard share with voting and (if declared) dividends.
- Preferred: dividend priority, no voting, fixed dividend. Most US listings are common.
If the company goes bankrupt? Shareholders are last. Bondholders first, then preferred stock, then common. Diversification is critical: single-stock bankruptcy risk is 20%+.
