## Questions and answers from the visible page

### What is a good asset allocation?

A common heuristic is to hold roughly (100 − your age)% in equity, with the rest in debt. It is a starting point, not a rule — your horizon and risk tolerance matter more.

### Why does allocation matter more than fund choice?

Studies consistently find the equity/debt split explains most of the variation in portfolio returns over time. Picking the right fund is a smaller lever than picking the right mix.

### How often should I rebalance?

Annually, or when an allocation drifts more than about 5% from target. Rebalancing enforces selling high and buying low.
