In this zero sum game, they create and destroy bubbles at the retail investors' expense. Don't be their stooge. Take the profit and count your blessings. The worldwide recession has already begun. Hope may be good for getting presidents elected but it's NOT good for trading. Believe me, I've been trading for 33 years and have made countless mistakes. The fact that the markets are are near 5 year high is a miracle in itself given the backdrop. Please take profits now or at least after the fiscal cliff is kicked down the road and holiday sales 'beat' followed by a strong yet brief rally.
