imho, that fat finger theory is just sleeping pills for idiots. DJI has done more than 250 points/day swing at least 3 times this year, and yesterday it closed 340 point down and this morning went 200 points under once again. It is like the earthquake warning signs. Of course main streams are trying their best to blur the water, just like what Benny and Hennry did 1-2 mths before the 2008 crash. cause big boys either need time to get out or they don't want investors to flee from the stock market.
