Narrative:
We were assigned holding at camrn at 12;000 feet. Determined that our target maneuvering airspeed was 182 knots so decided to hold at 200 KIAS. After starting the outbound turn; we were assigned a descent to 11;000. Almost immediately after we entered heavy precipitation which caused the ice light to illuminate despite the total air temperature being plus 12. We also immediately encountered moderate turbulence. Captain (ca) was heads down sending an ACARS to dispatch about the hold. As the aircraft (on autopilot) rolled to the right to fly the outbound leg; another good jolt of turbulence caused a 15-20 knot loss in indicated airspeed. This combined with the bank angle; and engine and wing anti ice being turned on caused the stick shaker to momentarily activate disconnecting the autopilot. By the time the ca was 'heads up' the first officer/pilot flying had over corrected the recovery and was climbing through 12;800. We notified ATC and were told to continue to 11;000 when able. There were no secondary stall notifications.
