Just because one tiny fund screwed up once does not mean that it is anywhere near likely that any ETF would screw up in a manner that would trigger this poison pill.

$15bn is tiny, presumably we’re talking about big ETFs like SPY here.

And anyway, you’re pretty much agreeing with me. It’s absolutely possible for a big fund to make a huge and hilariously stupid mistake, but this twitter poison pill does not meaningfully affect the chances of that happening.

In a world where you can shoot yourself in the foot in a million ways, it is utterly pointless to speculate about this one extraordinarily unlikely situation.
