Doubling down is risky business, but it depends on your risk appetite
I have only a small stake in AC8 (every speccy I have is miniscule compared to my holdings in A2M and CSL) and I was tempted to take some more, but now that it is back at break even for me I will just see what happens.
The small end of the market is a fickle beast and having any more than 10% of your folio in it is brave IMHO but each to their own
