You see, the problem that I have with these kind of "explanations", is that those facts have been around for a long time. Why is it that precisely today (well, yesterday) was the day that everyone decided "right guys, we're selling equities"?
The things you describe explain why people keep their finger hovering over the "sell" button, they don't explain why precisely today they decided to press it.
