Well, Retail sales seem at best poor.
Housing has been in the crapper for a while now. I haven't seen any evidence that business investment has done anything. And considering that last quarter GDP was probably closer to 1% than 2% (we will find out more in 3 days).
I also have a personal economic indicator that just recently flipped. It hit before in 1987,1990,2001. It isn't a real one but something that seems to happen at or near an economic peak.
I think recession is pretty much a given at this point.
