The lesson
A 50% fall is painful. A forced sale can make it permanent.
In this illustration, a €100,000 portfolio falls to €50,000. If it then fully recovers, it returns to €100,000—provided nothing was sold.
Withdraw €20,000 at the low and €30,000 remains. If that balance doubles, it becomes €60,000. The future gap is €40,000: the cash spent plus the recovery it never receives.
This model isolates liquidity. No recovery is guaranteed, and price risk is not the only risk: business deterioration, excessive leverage and paying too much can also make a loss permanent.
