Question for Fruitcake (and BBS)

Currently, stock prices are generally up.
I've heard concerns from politicians, as well as corporate CEOs, that the sequester and related items (i.e. not just the sequester) would result in a sharp downturn of the economy, including with respect to stock prices.
Thoughts on why there is a contradiction between expectations and reality? I know economists and politicians get it wrong as often as they get it right, but it's a bit confusing that there was so much agreement as to the forecast, which is vastly different than the reality. Are we expecting a correction to the stock market in the near future?
