Usually after April 15 until around May 1st....Wall Street does it's annual Sucker Flush.....
It happens every year.....about this time.... Essentially stocks can't go up forever...and you have to flush out the retail plungers so the markets and "the float" can regain their equilibria after the massive Q1 pension funding is over.
Also, the first quarter "happy talk" is wearing thin by now...as reality sets it for the rest of the year. Hence, the need for a "flush"....
This year could be especially bad because of rate hikes, oil prices, the dollar, our real estate bubble, and the massive trade deficit. Not to mention consumer debt that is now NON dischargable in bankruptcy....! Beware Big Spenders.
