Challenger-500 flight crew reported the stick shaker activated during departure. They performed stall recovery and returned to the assigned course with minimum loss of altitude.

Narrative

I received a stick shaker and the stick pusher activation during departure at ZZZ. I performed stall recovery. It appeared to me to be a minimal loss of altitude. We recovered back to assigned course and altitude. ATC or passenger did not give any indication of knowledge of the event. We departed RWY XX from ZZZ cleared for the ZZZZZ DEPARTURE. After the FRA (Flap Retraction Altitude) (400 ft agl). I noticed the course on the MFD (Multi-function Flight Display) did not reflect the ZZZZZ DEPT. I asked the PM to verify the departure. He said it was not loaded and started to reload it. I engaged the autopilot and looked at the departure displayed on the PM MFD. About the same time I received the stick shaker/pusher and initiated recovery. About this time ATC told us to turn to a heading and climb. We verified we were ok and initiated the ATC instruction.What happened; I'm not 100% sure but in retrospect here is what I think I did. I thought we had done everything IAW (In Accordance With) the AOM. We briefed the departure then I asked the PM to read the waypoints from the FMS while I verified them. He read ZZZZZ1 from the FMS; that was the first point on the release. Neither of us realizes that the departure was not loaded. We had just briefed it from the chart displayed on the MFD. At the time in my mind the briefing was the route verification. I know that is not correct and don't know why I did not catch the mistake. During the climbout when I noticed the lack of departure I lost track of power/airspeed and let the plane slow causing the stick shaker/pusher. Adding to the event the climb out was into the sun making it difficult to see the instrument panel. Not a cause but definitely an additional stressors.
