Using the base method, the percentage change is calculated as (New Price - Old Price) / Old Price * 100 = (2 - 4) / 4 * 100 = -50%. Using the midpoint method, the percentage change is calculated as (New Price - Old Price) / ((Old Price + New Price) / 2) * 100 = (2 - 4) / ((4 + 2) / 2) * 100 = -2 / 3 * 100 = -66.67%, which rounds to -67%.
