Hi, you could set up different portfolios within your IE account and test your theory - just make sure that you create and fund all of your test portfolios for the same theory on the same day/at the same time.
The amounts you put in there don’t need to be big - after all it is just for testing theories.
It could look like this, for instance:
Portfolio 1 - Vanguard
Vanguard FTSE All-World UCITS ETF Distributing, ISIN: IE00B3RBWM25, EPIC: VWRL
Portfolio 2 - Vanguard
Vanguard FTSE All-World UCITS ETF (USD) Accumulating, ISIN: IE00BK5BQT80, EPIC: VWRP
Portfolio 3 - Invesco
Invesco FTSE All-World UCITS ETF Acc, ISIN: IE000716YHJ7, EPIC: FWRG
Portfolio 4 - Invesco
Invesco FTSE All-World UCITS ETF Dist, ISIN: IE0000QLH0G6, EPIC: FTWG
For the above portfolios weight is automatically 100%.
If you want to try out different weight / multiple ETF’s it could look like that:
Portfolio 5 - Vanguard All World (70%) + Bonds (30%), Accumulating
FTSE All-World UCITS ETF, includes Emerging Markets, EPIC: VWRP
Global Aggregate Bond UCITS ETF, includes Emerging Markets, ISIN: IE00BG47K971, PIC: VAGS
And so on.
You may find that ETF’s covering the same region but from different providers are producing very similar results. At which point it could be more about costs and size of the ETF in question, size of tracking error, are they tracking the same index or a subset etc. As for share price - as you’re buying fractions of shares - surely share price is irrelevant?
I quite like JUSTETF for research - https://www.justetf.com/uk/find-etf.html.
Also worth doing is looking at how different filter settings influence outcome of ETF’s shown.
Have fun and good luck!
