Bonds for newbies

[Ex Pat]

Hey,

My IPS says that I should start adding bonds into my portfolio at the end of they year.

What I put in my IPS (and now I have to actually understand and realize what this means in practice) is :

Bonds will be CHF-denominated, investment-grade, via a low-cost broad ETF with short-to-intermediate duration.

And I also got this advice from @Rttm

Uncorrelated assets combined with regular rebalancing lead to a much more stable portfolio (reducing volatility and, consequently, making a "lost decade" less likely), while also theoretically improving performance (see Shannon’s Demon: https://www.richmondquant.com/news/...tfolio-returns-can-be-created-out-of-thin-air).

The problem that I have is that I don't know where to start, and what those "CHF-denominated, investment-grade, via a low-cost broad ETF" bonds should look like.

Is it better to look only in government bonds, or also industrial bonds because Swiss companies tend to be stable?
