And TuMaRu let me add as a former futures trader from 1990's, today, the US securities (Equities) markets, mainly due to total electronic trading, has been turned into a scenario worse than the actual Futures markets as far as volatility and should NEVER have been allowed to occur.
Yes BIG banks/Funds/Hands manipulate and control them and literally, the SEC filings, news, PR's, etc is a meaningless con on the general public, and mean nothing any longer as those "big hands" can make or break any market or stock at their whim; especially in shortsell schemes, and it needs to be curbed and integrity brought back into Equities markets again...
Just my 2 cents here...
