wall, if there were nothing to worry about, then no one could make money on stocks.
Like the recent 19% downturn in the SP500 seemed exaggerated, and at the time everything was all double dip in the news, now that good earnings are coming in, the rallies look good only because the market was already down so far.
Not that there is manipulation, no one would stoop to that sort of thing just to make a lot of money.
I like to think of it as information management. Give the people what they want to hear, where there is fear, let them know how bad things can get, where there is greed, the sky is the limit. The timing is only coincidental.
