They don’t like speculative AIM shares in general, if you were only using Freetrade you would have missed out on all of the huge pharma risers of the past two months (NCYT, SNG, AVCT) to name but three.
It’s one of the major drawbacks right now as far as I’m concerned. Hargreaves have the entire UK stock universe to choose from & that is a very important aspect for me. If I read a positive RNS from an AIM stock, I want to be able to have the choice to buy it in my ISA. US stocks are interesting, but it’s high time more £20 - £100m market caps were added so users can speculate accumulate as well as holding ETFs and large caps for the long term.
