I hope for you it is just a pause. Everything that has happened in the last 2 days and the 3 weeks before that is consistent with a climax top.
BIDU was not an isolated case today. A lot of leaders took it on the chin. One distribution day by itself does not spell doom but this is not the first one and the market has been struggling for 6 months after a year and a half of insanity.
My advice is to take profit and keep watching closely. That 107 open may become a star in the sky in the coming weeks.
