Why the 8-4-3 Rule Changes How You Think About Risk

The FundsIndia Wealth Conversations report introduced the "8-4-3 rule" of compounding – a framework that shows how long an investor must stay in equities to see wealth accelerate. For the practical trader or long-term allocator, this rule is not a marketing gimmick. It is a direct challenge to the most common portfolio error: selling too early.

At a monthly SIP of ₹70,000 and an assumed 12% annual return, reaching the first ₹1.1 crore takes about 8 years. The second ₹1.1 crore takes 4 years. Every subsequent ₹1.1 crore after that comes in 3 years or less. By year 20, the portfolio adds roughly ₹1 crore per year.

Most investors stop before the 8-year mark. The rule quantifies exactly what they forfeit.
