An Index Expirement

If you had to pick 20 long running indices that ideally have ETFs covering different markets / sectors, what would the top 20 be?

I’m looking to see if you can run back analysis on when one over or under performs the others over a period of time, do they revert back to norm?

As a baseline I think there needs to be:

  • FTSE All World or MSCI world index
  • SSE Composite (China)
  • Sensex (India)
  • Topic (Japan)
  • FTSE 250 or ASX
  • Nasdaq / S&P500
  • Clean energy
  • Global resources
  • Gold
  • Global Small Cap Index
  • Some sore of private equity / VCT tracker

So what ETFs would you pick for each / what would you add
/ remove?

The only index I invest in is gponal and at the moment I am all in on HMWO.

What about any US or North Americans?
