What does the MSCI ACWI Index track?
ACWI stands for All Country World Index: about 2,500 large and mid-sized companies across 23 developed and 24 emerging markets, maintained by MSCI.
One number for "how did the world's stock markets do today" — the US is the biggest slice, but Japan, Europe, China and many others are in the basket too.
MSCI
Every figure here is in pounds — what you'd actually pocket buying on the London Stock Exchange. Fund fact sheets usually headline returns in US dollars, which can look very different in years when the pound moves against the dollar. Here's the full story, year by year.
