Narrative:
Due to weather we were placed into holding twice. The second hold was to last well over an hour in addition to the previous 40 min hold. Captain went back to advise passenger that a diversion was likely. The captain heard an increase in power followed by a turn and descent. Captain immediately returned to the cockpit to find the first officer had almost stalled the aircraft and immediately took control; but lost 500 ft of altitude in recovery. ATC was advised and issued a descent to FL310 with no traffic conflict. First officer could not explain what he did as the aircraft was on autopilot with power adequately set. First officer said he thought it was turbulence from the nearby convective activity. [During departure] the first officer mistakenly entered the wrong fix; which the captain quickly caught and corrected.
