Market preview: With no rabbits expected to be pulled from Bernanke's hat, S&P futures -0.8% and following Europe lower. At 10 a.m., Bernanke will at long last deliver his Jackson Hole speech, and investors can get back to focusing on fundamentals - which aren't too hot, as evidenced by the reduced estimate for Q2 GDP growth. Also ahead: consumer sentiment.
