A point to remember when comparing percentage rises and falls is that the percentage fall does not have to be as great to take you back down to where you started because it is from a higher capital base.
i.e.
If you have a dollar and it rises by 50% you have $1.50,
to get back to $1 would require a fall of 33.3%
A fall of 50% from $1.50 takes you to 75c.
