However I dont understand what you mean by checking if more "trackers" isnt eating away the 0,2%" What are trackers and how can they eat away my profits?
Oh, just a name, but the index funds you are buying are trackers. They try to mimic an index, such as S&P, MSCI ... , thus they
track an index.
It doesnt cost more if i buy 1 or 10 funds. There are no sale or buying costs except for a small currency transaction fee, but it is levied on the amount being transacted, not on the number of funds.
No problem then. Rules are just different in every country, and with every bank. Some banks charge a flat fee for a transaction (regardless of the cost), others charge based on the amount of the transaction. It is the flat fee that can really eat into your investment if you invest in too many funds, but you seem to be lucky!
Yes I will rebalance. I will not sell any funds because that will interfere with the interest-interest effect and I once I sell the fund I will have to pay capital gains tax. So my solution is Dollar cost averaging and if im short on for instance the emerging market fund and I need to rebalance this then I will buy only this fund when I get my paycheck and this will act as rebalancing tool.
Excellent plan :). This might not work after one or two decades, but then you will be swimming in money anyway ;).
But there is also one more thing I dont understand. What is the difference between ETF's and traditional index funds. I know that in traditional index funds you cant buy and sell them during the trading hours of the stock exchange. If you for instance buy it at 9am you will get to purchase it at the price it was valued when the trading stops at the end of the day. While ETF's you can buy at 10 am and potentially sell at 11 am with a profit. But is there any other difference between these types? Like costs or risks?
You already list the biggest difference. An ETF is like a stock. You can sell it whenever you want, as long as you can find a buyer. This is immediately one of the risks. If there is an extreme market crash, nobody might be interested in buying it and you will have to significantly reduce the price. Of course, during such an extensive market crash it stands to reason that also traditional index funds will quickly loose their value. Since you can sell ETFs so easily, don't let yourself be swayed into day trading. ETFs and index funds in general really should be bought for the (very) long term. Buy and forget! Costs for both options seem to be on par. Finally, ETFs can sometimes be
virtual. It shouldn't really matter, but some ETF don't buy actual shares but instead use tools such as futures. This is a good thing for you as it reduces the
tracking error, which is the difference between the ETF and the index it is tracking. However, if things are to go very, very bad then futures will be worthless whereas the actual shares might still have been worth something. To be fair, I wouldn't worry too much about it, and it can be very difficult to figure whether an ETF uses futures or not.
