I like to look for tenacious long term trends and then look for stocks that got perhaps too overheated/over-extended. Then if those same stocks fall 50% AND the long term trend (of the sector) is still up I blindly buy those stocks and add them to my portfolio. GoldCorp (GG) was a recent good example of this. This strategy worked very well in the tech boom, basically let everyone else get caught up in the short term rubbish while you don't lose sight on the bigger picture.
long oct natural gas, short nov natural gas spread. a few big NG contracts. entered with spread at ~1.90 avg and exited avg a little more than a buck below that. very nice trade.. nice to be on the other side of Amaranth.
I traded US$50 for a 80 year old pencil drawing of Albert Einstein, hand signed by the artist and Einstein. The piece was appraised for US$25,000.00. The transaction took 1 day.
