Low TER Accumulating ETF on Degiro

You are mixing things up in this thread.

  1. You have to know how you want to diversify your portfolio.
  2. Go buy some ETF on Degiro that covers that diversification with your first 1000.-
  3. Check your Degiro account on all the costs it created.
  4. After some days check how it changed in value.

You will realize, that the market changes much more then the 0.X% you are trying to understand.

% difference between best ask and bid prices. When the exchange is open.

Not really. Or not that much.

They primarily prefer US-domiciled “World” funds for their low costs and tax advantages (both recurring cost factors).

Though you can, as of now, also buy them at Swiss brokers.
