I recently saw a youtube video that compares msci world vs a yearly "rebalanced" portfolio of msci region etfs. the "rebalancing" does not mean selling anything, but only buying the underperforming regions so ensure it's always at equal proportions in terms of % of the portfolio. it was claims this portfolio was superior to msci world itself.
I would like to check and backtest this claim.
therefore, I'm looking for a tool that allows me to:
* create a portfolio (virtually, I dont want to buy anything)
* simulate the portfolio using different start dates
* factor in buying the underrepresented etfs once a year
* compare with msci world performance
would anyone know a tool that can do this?
thanks!
