I think they’ve been pretty hopeless on quality and then technologist and growth in particular. They’ve been woeful - if you followed their best ideas over the last decade i think you would have underperformed the index if you just equally weighted.
I think the australian investment industry was very value orientated over the decades and morningstar was slow to adapt. Guess hard to go from banks and miners to learning about PME/XRO/ALU etc.
Theyve bought in the new tech analyst now who is pretty much only growth though - not the one covering PWR.
Growth has also had an amazing decade and there’s a scarcity premium on the ASX that results in growth trading at stupid valuations at points too.
I think they’ve been okay in old industrials etc. Banks they’ve had wrong too with WBC on best ideas a few years ago with a high ‘stewardship’ and ‘capital allocation’ rating even through the whole money laundering child exploitation scandal. They only removed it a year or so ago.
