On another hand, many people seen these news the whole month and expected this pullback, just couldn’t understand why it wasn’t happening sooner. Plenty of other bad news are coming up all the time and nothing happens.
So it’s not really the news, but which big guys decide to press the Sell button. And they decide how to interpret any news, and based on how they were positioned or how they want to be positioned.
(just my 2 cents, I’m only qualified to speculate as much as anyone else)
