The lesson
The loss is 50%. The recovery is 100%.
Start with €100. A 50% loss leaves €50. To return to €100, the remaining €50 must gain €50—which is a 100% return on its smaller base.
This is not pessimism; it is percentage arithmetic. As losses deepen, the return needed merely to break even becomes larger.
A price move is not automatically permanent loss. But weak business economics, leverage or paying too much can make a deep loss much harder to recover. That is why the downside deserves attention before the story of a potential gain.
