Markets are waiting for possible Jackson Hole surprise from central bankers:

• The Fed's long anticipated annual Jackson Hole symposium features high-profile speeches from Fed Chair Janet Yellen and European Central Bank President Mario Draghi.

• Draghi was expected to be the central banker who could affect markets most and reveal new policy details, but now some strategists say it could be Yellen instead.

• Yellen speaks at 10 a.m. ET, and Draghi speaks at 3 p.m. ET.
