I am an (unhappy) Swissquote customer since many years and so, every now and then I check for better alternatives that would work for me. I only invest in mutual funds (and occasionally in ETFs).
A year or two ago I looked at Interactive Brockers (which apparently are the cheapest option around), and today I did another check. My problem with IB: they don’t offer almost any of the mutual funds that I hold in my portfolio. To be precise, IB only offer 2 out of 8 (by comparison Swissquote has 6 out of 8). Postfinance (which apparently uses Swissquote platform with somewhat different pricing and range of available products) offers 5 out of 8 and but is a little cheaper than Swissquote.
I would be grateful for any suggestions with respect to finding a broker that has better choice and lower cost than Swissquote or Postfinance when it comes to mutual funds.
