The ATSB said (
http://www.atsb.gov.au/publications/...503722_001.pdf ):
"The autopilot was manually disconnected and nose down column was applied by the crew. The aircraft pitched to 18 degrees nose up and climbed to approximately FL410 with a rate of climb up to 10,560 feet per minute (fpm). The airspeed decreased from 270 kts to 158 kts. The autopilot (A/P) overspeed and stall protection activated simultaneously and the autopilot flight director system (AFDS) pitch mode failed prior to A/P disconnection. The stick shakers activated near the top of the climb."
In the ATSB animation of the recoded data, you can see around the 1 minute mark with the autopilot disconnect, forward movement of the control column and manual reduction of thrust the aircraft continues to pitch up.
