The simplest policy for the defensive investor is to invest a fixed amount at regular intervals.

— _The Intelligent Investor_，1949

🏠 Everyday Analogy

Just as one might set aside a fixed amount of money each month to buy rice—regardless of whether the price rises or falls—by consistently purchasing the same monetary value of rice each month, you buy less when prices are high and more when prices are low, achieving the optimal average cost over the long term. The same principle applies to investing: regularly investing a fixed amount allows time and compound interest to work in your favor.

💎 Key Insight：Dollar-cost averaging is the simplest antidote to market timing. By investing a fixed sum regularly regardless of price, you automatically buy more shares when prices are low and fewer when high.
