Well, this is a stock with a Billion shares outstanding and daily trade volume 35-40 million and of a wellknown company throughout the world with wide-ranging products usage - a perfect company for the Wall Street institutional crooks to keep the price swings large enough for making millions a week without being detected. They band together - thanks to the MM - to do so. All these crooks make money while those ignorant of this game loose!! This is true not just for AA but many such other companies. For these crooks, it's just a casino game - thanks to the cooperating SEC!!
