It helps to understand just what climactic action represents, the difficulty sellers have in finding an ask that buyers are willing to pay, and if sellers become desperate enough, they may, as with a parabolic move, have to lower their asks substantially (if one looks at a tick chart, he will see the gaps that occur during these rapid and dramatic moves). At some point, for whatever reasons are important to them, enough buyers will step up to halt this movement, and sellers and buyers can once again find equilibrium. None of this means that buyers are right, it just explains the dynamics of the movement. If enough buyers step up and sellers are again able to get their prices, price will reverse. But if there aren't enough buyers to absorb what sellers want to sell, price will then resume the decline.
