BeginnerWhat is the relationship between risk and return?
Higher expected return usually requires taking higher uncertainty. The key is whether the risk is understandable and affordable for you.
Quick Definition
Higher potential returns come with higher risk — this is the fundamental risk-return tradeoff. Smart investing isn't about avoiding risk; it's about taking only the risk you understand and can afford.

What does diversification mean?
Diversification means spreading investments across different assets, sectors, or regions to reduce risk. When one holding falls, others may offset the loss — don't put all eggs in one basket.
What is dollar-cost averaging?
Dollar-cost averaging (DCA) means investing a fixed sum at regular intervals regardless of price. You buy more shares when prices are low and fewer when high, naturally lowering your average cost.
What is inflation and why does it matter?
Inflation is the rate at which prices rise over time, eroding purchasing power. Central banks typically target 2% annual inflation. High inflation hurts bond returns and raises borrowing costs.
