iShares Core € Corp Bond vs iShares $ Treasury Bond 7-10yr
iShares Core € Corp Bond tracks Bloomberg Euro Corporate and iShares $ Treasury Bond 7-10yr tracks ICE US Treasury 7-10 Year. They are realistic alternatives for the same slot in a portfolio, but because the indices are different nobody can tell you in advance which will return more. What can be compared objectively is the cost, the replication method, the domicile and how each one is structured — and that is what this page does.

Which one will perform better?+
Nobody can know that: they track different indices, so their returns will diverge, and past index performance is not a prediction. What you can control today is the cost, the tax structure and whether the index actually covers what you want exposure to.
Which one is cheaper?+

Accumulating or distributing?+
