Here is simple mathematical forumla -
1. Suppose you own a stock at Rs 100 and it goes down to Rs 50. So how much %age it has fallen? Yes, you are right..it is exactly 50% fall.
2. Now from Rs 50 to take it back to your original price of Rs 100, how much %age it needs?, Yes, you are right…it exactly needed 100% to reach to your original price of Rs 100.
This means to move a stock up it needs double the strength. That is the reason stocks fall quicker but move up much slower.
In another words,
1) if a stock falls 50% in 1 year than it will take 2 yrs to reach to original price. OR
2) it needs double the volume to move upto original price. This is where importance of volume comes into picture.
