Pinned straw:
I’m getting more comfortable with CSL and taken a small position in my real portfolio. I’ve landed on/applied a broader investing rule for companies I don’t fully understand. If the division I can get my head around is potentially worth close to the current market cap then the other divisions can be viewed as free options and I don’t need to understand them at outset.
The other thing that matters is that debt isn’t such that it can bring the whole thing undone if a division that I do or don’t understand underperforms. This is a similar rationale for my small holding in mineral resources where debt is more of an issue.
This approach opens up a lot of investment opportunities.
