Narrative:
Enroute; allowed first officer to hand fly aircraft; he leveled off at 10;000 ft (assigned by air traffic control). While accelerating we hit some turbulence (I think it was wake turbulence) and lost 300 ft of altitude. After repeating altitude call outs; I took the aircraft and climbed back to altitude. Center repeated 10;000 ft assignment and I acknowledged altitude.
