I would like to diversify my portfolio and buy some foreign corporate bonds. For example, let's say bonds from French companies.
On paper it sounds rather mundane, however I am having the hardest time finding the bonds and comparing them. For example, I would like to know:
\- What are the bonds with the largest trading volume?
\- Where can I see the order book for those?
\- Is there a way to get some kind of rankings (e.g. "Here are the bonds by public French companies ranked by their market cap (or revenue)"?
All this info is super easy to get for stocks, but somehow I'm unable to find this for bonds. Am I missing something?
PS: Not asking for financial advice, that's really a purely technical question.
