Add one to the confused group.
especially now in the earning season you find stocks fall 25% and more because they miss earnings by 1cent, but they never go up 25% if they earn better than expectations.
[My imagination] big funds with Billions in the market they just decide to go out and they go out at once so they push the price all the way down, but when they go in they go in slowly so they will not have huge impact on the price. Sounds stupid since they will lose more when they drop the price like this anyhow for me this is VOODOO
