Key Concepts in Investing

Compound Interest: The process where your earnings generate their own earnings, creating exponential growth over time. Even modest returns can accumulate significantly over decades.

Return on Investment (ROI): The percentage gain or loss on an investment relative to what you put in. Annualized ROI normalizes returns across different time periods for fair comparison.

Dollar Cost Averaging: Investing a fixed amount regularly regardless of market price. This approach reduces timing risk and can outperform lump sum investing in volatile markets.

Dividend Reinvestment: Using dividend payments to buy more shares creates a compounding effect that can significantly boost long-term wealth.

Inflation Impact: Understanding real returns (adjusted for inflation) is crucial. A 5% return in a 3% inflation environment is actually only a 2% real gain in purchasing power.
