While I want to keep at least €50.000 on hand for big plans and emergencies as cited above, I would like to invest about €100.000.
You’re starting at the wrong end of the problem imo. The question is not how do I invest an arbitrary proportion of my wealth. What you should be asking yourself is what do you want/need to get from that wealth and then applying it in such a way as to maximise the chance of successfully doing so. Otherwise you’re just asking for validation of a smattering of preconceived plans (take 4k per annum from AVC - why not 6k or 2k? Invest 100k, nice round number but why not 90k or 110k? 50k rainy day/ big trip fund, why not 40k/60k?, etc.).
Brendan and others have made some really good suggestions but again, feels like they’re more like options to consider without really understanding your underlying objectives.
