Bloomberg is claiming it went up because Neo-Communist Paul Krugman said the recession would end by September.
Krugman is part of the gang enlisted with talking up the economy. In the end it will fail because the reality is other then what he and the rest of the media are claiming. Only today Obamahussein was quoted as saying the recession is very serious and will take a long time to recover from. Of course knowing him it could well be an attempt to greatly lower expectations and inoculate himself against a prolonged recession at the same time.
Bottom line is if anyone could forecast the end of an economic cycle, up or down he would be wealthy beyond belief and would not have to waste his time writing for a liberal rag like the Slimes.
