Yes, the tax saving should be around 0.25% per year.
Note that the MSCI world only covers around 75% of the total world market. It is missing small caps and emerging markets (and frontier markets, but nobody cares about them)
I only found the holdings in the halve annual report.
Here is a portfolio, that covers a bit more and avoids small cap growth companies:
However it also misses Small caps from Japan, Australia, Canada and Israel.
Don’t time the market. It is not a sound strategy.
