One of the commentators was asserting that was the case.
ie "you aren't really sticking it to big money, you're just a patsy for one group of billionaires against the other".
The cynicism is appealing under the circumstances, but the evidence is lacking.
ASX is fairly heavily regulated. Noone was heavily shorting GME on the ASX because it's not a viable strategy. Naked short selling attracts punitive regulation (as opposed to whatever the SEC supposedly does, although not to the same extent as
some), so you're not getting short interest over 100% here. The biggest risk of a stock squeeze on the ASX was Invocare, which had a short interest of 8.1%.
The fact that a bunch of investors:
a.) didn't realise that GME on the ASX was a different company
b.) didn't realise that noone was shorting it
c.) bought it in sufficient quantities to trigger a regulatory halt anyway
Is pretty compelling evidence that it really is just a viral trend on social media.
