Nonsense. When a pump is on, the pumpers begin selling into volume very quickly. Naturally the MMs short to meet demand, but they cover that fast. - janice shell
Along side the pump are market makers shorting, and covering when the pump is over. Kind of makes one go "hmmmmmm".
Too often it may be actually be a short selling scam disguised as a "pump". Isn't it ironic that the "panic" immediately follows the pump much too often?
