These numbers are a joke. Every month they revise the previous months' numbers nigher by 25,000-35,000 more jobless. All the government numbers are manipulated. It's ridiculous that the market watches them so closely.
Numbers are revised up and down...it's completely legit for numbers to not be finalized immediately...It's not manipulation, it's simply logistics. As more data comes in after the original number has been announced, the unemployment number is revised.
+1 *** In the normal process of data gathering and analysis, what Kassz007 says is true, numbers are revised as legitimate new information comes days (or weeks) after the initial numbers were release. But in the case of the government it's really just a huge game of three-card-monty, where they shuffle numbers and plays games with everyone's perception of economic reality. The game works until it doesn't, and that's what generates the 80 to 100pt down moves in the S&P 500.
