Why it moves the price

Markets read the return as a credible commitment to fix strategy, and often as a signal the board admits the current path failed.

What separates a good call from a naive one

The initial pop reflects hope, not results. Ask whether the returning leader's edge still applies to the company's current problem β€” the skills that built a business are not always the skills that repair one.
