Calendar-year and 12-month returns

How it is done

1. 1

   Every close is converted to pounds at the reference exchange rate for the day it closed.

2. 2

   Over our weekly history a year runs between the weekly closes nearest 31 December (up to ten days before or four after), and the table then shows the dates used; where we hold daily closes the date is exact.

3. 3

   A year the record does not fully cover is left out, never estimated — including the year a fund launched, and any year before its stated launch date.

4. 4

   A year is left out if most of its weeks have no close, or if it holds a weekly move of more than +50% or −33% in a fund that is not leveraged (a data break, not a market move).

5. 5

   Real returns deflate by CPIH from December to December. The year-to-date figure is deflated over the same number of months, ending at the latest month published.

6. 6

   The 12-month periods end at the latest calendar quarter end the record reaches. All five are always listed; a period the record does not cover shows no figure.

Limits to know about

• Past performance is not a guide to future returns.
• These are price returns. For a distributing fund the income paid out is not included, and each figure says so. For some funds our older records (to July 2026) reinvest income; figures covering those years are labelled as total returns, or as partly so, only where the fund’s reported total return confirms it. Where it does not, those records are treated as prices, and where they match neither they are left out.
• Weekly closes can put a year’s end a few days either side of 31 December, which can move a figure by a percentage point or so in a volatile week.
