Why it moves the price
A CEO change resets the market's estimate of future strategy and execution quality. The stock reprices to the new expected path, not to the news itself.
What separates a good call from a naive one
Direction depends almost entirely on context. Ousting an underperformer usually pops the stock (the market prices in a turnaround). Losing a respected operator, or an abrupt exit with no successor named, usually sells off — abruptness itself signals trouble. A star hire from outside can add more than the departure removes.
