Stock Investing 101: From Opening an Account to Your First Trade
Investing in stocks isn't gambling. It's buying ownership in great companies and sharing their growth.
Three Things to Understand First
1. What is a stock?
Buying a stock = becoming a partial owner of that company. Company grows β your shares appreciate. Company struggles β shares decline.
2. Investing vs Speculating
| Investing | Speculating | |
|---|---|---|
| Focus | Company fundamentals | Price movements |
| Timeline | 1+ years | Days to months |
| Profit source | Growth + dividends | Price volatility |
| Win rate | Higher (long-term) | Lower (most lose) |
3. Why most people lose money
- Buy high, sell low (follow the crowd)
- Trade too frequently (fees eat returns)
- Buy based on tips (no independent judgment)
- No research (don't know what they own)
Essential Terms
| Term | Meaning |
|---|---|
| PE Ratio | Price Γ· Earnings per share β valuation measure |
| Market Cap | Total shares Γ price β company's market value |
| Dividend | Company sharing profits with shareholders |
| ETF | Exchange Traded Fund β basket of stocks |
