Energy builds up in a 'Wyckoff Cause', like a weight building building up on one end of the see saw, then the balance moves and we have the resulting swing and effect.
Wyckoff: The Law of Cause and Effect
In order for there to be an effect (change in price), there needs to be a cause. The effect will be in direct proportion to that cause. Best price moves occur when there has been enough time to allow for a period of accumulation or distribution (or in other words a cause).
If the trend does break down a 30% plus move down is very likely. The NYSE is very Wyckoff friendly with the law of cause and effect.

"Being in the market at all times is not the key to profits. Being in the market when there is a clear, unconfused technical signal, and the trader's judgment is not swayed by emotion, is the method for trading success." ~ Richard D Wyckoff
"Successful speculation requires staying on top of changes in industries and companies that either create new industries or improve on existing industries.
