german market dropped 1.7% in 5 minutes yester

german market was up roughly .9% then it dropped to roughly -.8% in about 5 minutes. the reason was the eu or someone cut the growth forecasts for nearly all euro zone countries.
it was a strong sell move and most euro analysts that im hearing are saying the markets are too high.
if the american numbers disappoint even slightly next week their going to sell off the american market quickly i believe.
