Why it moves the price
The board hires and fires the CEO and approves strategy. Changing its composition changes the probability of a strategic reset, a sale, or a shift in how capital is returned.
What separates a good call from a naive one
Board changes usually matter as a leading indicator of something bigger — a CEO exit or a sale process. Watch who joins: operators with sector experience signal a fix, bankers signal a sale.
