I got burned on the big move up today.
As best I can tell, it was caused by heavy short covering in the energy sector.
The move occurred shortly after Oil spiked up a dollar in just a few minutes and settled above $60.
Until now, the market appeared to have a negative correlation with oil. When Oil went up, stocks went down.
imho, that may relationship have changed, due to the current heavy short speculation in energy stocks.
The market taught me something new today. It was an expensive lesson.
