Built on checked data
Each series is the index's year-end close, checked against at least two independent records for every year. The same numbers back our returns-by-year reference tables, so you can see every year behind a result.
Past performance does not predict future returns. The calculator shows what the index itself did; it ignores fees, taxes and fund tracking error, and is not investment advice.
