What is the Buffett 50% drop rule?

It is a discipline test. Before buying, ask if you could hold a stock or fund through a 50% fall without panic or forced selling. If the answer is no, reduce size, improve quality, add cash buffers, or skip the idea. It is about preparation, not prediction.

How can Indian investors use this rule with index funds?

Decide an allocation to Nifty or Sensex funds that you can hold through large drawdowns. Keep 6 to 12 months of expenses in liquid instruments. Continue SIPs during declines. Rebalance annually or at set bands to add after falls and trim after rallies. Simplicity aids discipline.

Should I stop SIPs during a market crash?

Stopping SIPs often locks in fear. If your income and cash buffer are intact, continuing SIPs buys more units at lower prices and supports long-term returns. Pause only if your emergency fund is short or income is uncertain. The rule works best with steady contributions.

What asset mix suits a 50% drop test?

Pick a mix you can live with in a crash, then write it down. Many use 60-70% equity, 20-30% debt, and some gold, adjusted for age and goals. Rebalance yearly or at 5-10% bands. The best mix is the one you can hold through stress.
