The article and the submitted HN post both appear to have the same title to me: "Margin Call".

What are you talking about? Did one or the other have a different title when you wrote your comment?

Yes, an admin changed the headline.

Original headline was misleading and editorialized.

Got it. Out of curiosity, what was it?
