Simple. The private sector is worried that the government will continue its assault on private sector business. That the stock market rises during times of higher unemployment is nothing new and can be explained rather easily. Right now companies are doing a decent amount of work with fewer workers than they had before. The index used to discuss this is the level of productivity we often hear about in the financial news. Fewer workers doing the same amount of work or more, and for the same or less pay, can make companies more profitable, at least in the short run.
